I have a Z370 Gaming M5 motherboard with an RGB header, that's a 4 pin. My RGB fans are addressable RGB fans so they terminate as 3 pins. They all plug into an RGB fan hub but obviously the hub also has one of those ARGB 3 pins, how do I hook this up? What do I need to buy to make them work? Thank you! Also, they're pwm fans if that helps.

Hey, I have the hyper 212 evo, In a custom build gaming pc. But my pc is a blue led lit build and i dont want the red light on my hyper 212 led cooler. My question is if i can cut one of the fan wires to disable the led's, and if so will i still be able to control the fan speed? Also can i just disable the light with any software?

Hey guys, I have a question about the PWM control on 4pin fans. I want to run six fans off a single header, but they would draw too much current for that, so I want to run them off 12V from the PSU. To control the speed, I figured I can feed a single RPM wire to the fan header and have the PWM wires for all fans in parallel going to the fan header too. Would that work?

Hello guys, does anyone know how to control PWM fans with "Intel S5520HC" motherboard? Motherboard itself has 3x 4pin PWM headers, 2 for CPU's and one for system fan and also 4x additional 6pin fan headers (Motherboard Documentation - page 16). SpeedFan is only reading out 2 CPU fans (which are currently connected via a resistor, because otherwise they run on 100%) and it can't overwrite the motherboards PWM signal to them.. I've updated the BIOS & other motherboard firmware, sadly with no improvements. BIOS fan settings are not that "great" .. I've played with almost every possible combination but nothing seemed to change the fan speed. The "PWM Offset" setting sounds promising at first glance, but it's only for increasing the signal frequency - making things worse in this case. I know that there are third party PWM generators / controllers, but I'd like to keep it "tidy". Your help would be greatly appreciated!

Hello everyone, I'm in need of some big boy help. I have built a dual system inside of the Phanteks Enthoo Mini XL DS. I've been building this for a while now. Though I have a downfall that I'm trying to resolve. It started when I found out the fan hub in the back of this case is a 3 pin. So I get no PWM controls. Which is making my fans run at like 60-70% pretty much all the time. It's loud and annoying. However here's my hick up. I cannot just go out and buy a fan controller, because I need to hook up BOTH systems to this. Your standard fan controller won't be able to read both PWM signals. So I think I've come up with a solution but I'm not sure how to execute. I pretty much need to program a PLC to read both systems temperatures, select the highest temperature, send that signal to a PWM fan header and tell the fans what speed to run at. Basically I want to have my cake and eat it too. I need to find a way to have my case fans run on a temperature curve regardless of which OR both systems are on. Any ideas? Any tips? (Second system isn't hooked up yet, GPU is in the mail, once it's here the bottom system will be plugged up and running as well.) (I can run each system independently)

So I have this PC I built, the case has 3 fans I'd like to use. The issue is that the motherboard has only 2 pwm fan slots and both are used by the cpu cooler, pump being in CPU_FAN and the radiator fan in CASE_FAN. So either I find a MB with 5 fan slots or get a fan hub? I want to be able to control the fans via software if possible. https://nz.pcpartpicker.com/user/Joelboiboi/saved/#view=gMVLJx

Hi, I have a question for any EK Loop Connect fan hub owners. I'm planning a future PC upgrade and building a custom loop. The hub comes with 3 temperature probe connectors and 3 probes included. But I wanted to know if they are just for monitoring, or I could set up fan speed from the temperature readings? I think it doesnt make sense to run fans in a loop from the cpu or gpu temps, since the fans will be cooling the liquid, not the components themselves. I have this problem with the Cooler master masterliquid lite 240 aio. I had to set a fan curve to raise fan speeds only when the cpu is really hot, to avoid random spikes in fan speed.

I wanted to add about 4/5 case fans to my pc case but i only have 2 fan slots on my motherboard. I know you can get fan splitters but i've heard if you go over a certain voltage/current/wattage you can burn the motherboard pins. I can't find any sufficient sources to help me calculate what fans will work and how to calculate the power. I want to get the BeQuiet Silent Wings 3 120mm fan and do not know if i can have multiple on one slot. There are two versions - PWM and non-PWM. I do not know what that means. I have listed some info about my pc. Case: INWIN 101 Motherboard: AsRock B360M-HDV Power Supply: 650w Links to sources: https://www.asrock.com/MB/Intel/B360M-HDV/index.asp#Specification https://www.amazon.co.uk/quiet-Silent-Wings-High-Speed/dp/B01JMELYJA https://www.bequiet.com/en/casefans/718 https://www.in-win.com/en/gaming-chassis/101

Id like to ask if there is a possible way to control 3 pin fans on my a320m pro mobo. As of now it is all connected to molex which is irritating because of the noise. Please help

Hey guys... I have an idea I've been wanting to try, and I'm wondering if it will work... I have a picture I uploaded to this post, of a fan setup my uncle's friend did for their fish house, to use as ceiling fans and, not pictured, I did a single fan setup where it sits sideways in my uncle's fish house and he seems to find a benefit of some kind for it and I'm wondering if such a thing might work for a shop that's around 7-ft by 18-ft... Also remember, that the shop isn't currently finished, as it is in a barn that is basically all studs with the exception of the outer shell in other words it looks more like a pole barn than it does a actual barn, on account of it's still unfinished... Also uploaded, is a couple of pictures of what it might look like when it is completely finished... Also notice that the fans appeared to be hovering in midair a few inches down from the ceiling, and that will not be how it will end up working on account of the obvious fact that It's completely impossible for a fan to hang down with nothing attached to hold it in place, and have it function as desired... It will however if I can get it to, work slightly better than or at least look better than the one picture taken in a fish house... One thing you will notice is that there is that weird light in the corner of the room, and that is actually a light strip in case anybody wonders... I'm hoping I can get it to where the light strips provide enough light to where I can do computer building or fixing or any of that without needing extra light although if I needed extra light I probably would have a couple of RGB strips or something above my work area... It's mainly just something to where I can avoid as much light as I can in the setup itself of the ceiling, although, I may do either a light loop or a similar design fan or perhaps a cheap fan off of Amazon like what Jay's two cents tested, although I would have to figure out how to get it hooked up properly to the fan hubs that it comes with, although I will say whether I use a cheap fan or an expensive fan it would be kind of sweet if you ask me, to use one that could somehow, change colors... Perhaps have somebody make me a raspberry pi on the cheap or something that would control the lights, And I was already thinking a PWM controller for the actual fans but then the question becomes is there is such a thing as a fan cable being too long and then the fans would then start to lose speed with the power loss over the cable length without having any boosters which I assume there is no such thing for this purpose... Sorry for the long rant on all that, but it is something that I'm hoping somebody here might understand and might have some knowledge of... But before somebody posts about just using a ceiling fan, I am a computer geek, and therefore just having a couple of plugs hanging off the ceiling, that I can plug a ceiling fan into and then screw it to a couple of pegs or something hanging off the ceiling to me seems to be a more unique way of doing it than having even say a low profile actual fan... I know it would actually be probably less expensive to just have an actual fan, but again it's a PC nerd cave, for lack of a better term, that would also serve as a PC part storage room and as such I want it to be kind of unique... Mainly what I'm looking for, in an answer, is whether somebody with some knowledge on this subject thinks this could work, and if it could work, what the best way to implement it would be... I know I can get extenders and splitters and stuff off of cablemod.com, but generally they are only in as much as 3-ft lengths or something like that last I checked, so I'm sure that would get kind of spendy if I went that route, But if I did go that route, then I could have a splitter which would have one end hanging down through a small hole in the ceiling, and possibly be glued into place or something for the fan to connect to, the only other real problem would be when I hooked up the pwm controller, The one I'm looking at is ran by SATA power, So really the only two ways to do that if I went with the PWM controller route would be to either wire up a serial ATA power cable into a 12-volt line going back to my junction/fuse box using a similar setup to what an RV does, with a 12-volt circuit, or possibly if I did a raspberry pi type controller, for the LEDs or whatever, I could have it control that as well possibly but again I have no idea if any of this would work which is where you all come in... One last thing before I send this post off is the fact that I would not need a full 17-ft of wiring length because obviously I would only be using five fans to go from one end to the other, and I would not be going all the way to the other end however if I did go with a PWM controller or some other controller way of controlling it, I would have some kind of a controller sitting on my desk whether it be a pi or something else, And so figuring approximately seven or eight foot of height in the room, minus the height of the desk unless I decide to put the raspberry pi or whatever controller, on a shelf above the desk which then instead of being an extra 4 ft might only be 2 ft depending on how close to the ceiling I put it... So figure maybe 14 ft of distance from one end of the line to the other as a guess... Also, I might not do five fans in either direction, I might only do four or I might do six I really don't know what my number's going to end up being but I just had this idea in my head of putting fans on my ceiling because it might not be cheaper necessarily than to get a cheap ceiling fan but it just to me anyway sounds cooler... So anyone with constructive criticism, or ideas on how to actually make this work are definitely welcome to add their thoughts... I would prefer if nobody told me that it isn't going to work, without backing it up with data to prove that it won't work...(note that all the fans have to do is move the air around in the room, as that is their sole purpose)

Hello, So basically I want to ask is it possible to connect a Noctua NF-F12 industrial PPC 3000 PWM 4-pin fan to a 12V power supply. Do I just connect the positive and ground wire and ignore the control and sense wire? The two fans are not going into a PC I'm planning on to put them inside a closet to help get some fresh air for a Inverter. Thanks

These fans are the ones I am looking at to add in to my Corsair 280x case. I understand there are better options out there for cooling performance, but I like the look and they will fit my vision of my build (and they don't break the bank). I have an ASUS b450m a/csm matx motherboard and I plan on buying fan splitters because there are only 2 headers on this board (probably the Noctua ones that have black cabling). My question is are those Aigo Halo fans PWM or DC? I saw a post on reddit that said they weren't but they advertise it as PWM. Planning on installing them in the front of the case and move the pre-installed front fan to the top. So that way I'll have two fans at the top pushing air out and the two aigo fans pulling air in. Any thoughts, or other advice is welcome as well.

I do not know if there is a thread with this topic, but I bought a pump on ebay and was curious about turning it from non-pwm to pwm. It is a Laing DDC pump with one contact not being used. If I soldered a wire to it will it turn to a PWM?

So I've been looking into liquid cooling my PC and I think I've got the gist of it except for one thing. What do I base my fan/pump control off of? CPU or GPU? I'm doing a CPU and GPU loop and EK (liquid cooling guys) recommend a GPU to PWM fan adapter to have your GPU control some or all of the fans in the case if I'm doing more GPU intensive tasks. Now I don't necessarily do GPU intensive tasks except for gaming but I don't know if that is enough to base my entire pump or fan control off of the GPU for. I was thinking about having my GPU control the PWM pump speed while my motherboard headers control the fan speed. Is that smart or should I just leave it all alone and connect all the fans and pump control to the motherboard like a normal human. Thanks for any help!

If somebody knows a better or easier solution to switch off GPU fans please post it here. This was my solution for a silent PC build. I have quiet fans and SSD-s in my PC so the only noise source was the GPU fans since they are not the quiet type and you can't buy 75 cm be quiet CPU fans I came up with a different solution. To be able to switch off GPU fans: 1. You have to disconnect the fan PWM connector from the GPU. I have 2 fans on my GTX 970 they are joined together and they have a small male GPU PWM connector at the end connected to the female GPU PWM connector on the video card. 2. You have to connect the fan male PWM connector to your system PWM connector on the motherboard. You have to do some soldering or ask somebody to remove the small GPU connector and replace it with a normal size PWM male connector. (Somehow the GPU and motherboard PWM connectors are not the same size, also the wiring color differ.) Wiring for PWM fans: https://www.overclock.net/forum/61-water-cooling/1595707-ek-ddc-pump-pinout.html You can buy these cables for the soldering: 4 Pack PWM Fan Splitter Cable Y Splitter Computer PC Fan Power Cable 1 to 2 Converter, Black Sleeved Braided on Amazon or Ebay. 3. If the GPU cable is connected than you are ready to go. You will be able to control the GPU fans with SpeedFan http://www.almico.com/sfdownload.php Download link in this line: "The latest version is SpeedFan 4.52." 4. Since you connected your GPU fans to the motherboard PWM slot you can stop, start, set speeds, temperatures, curves etc via your motherboard. My motherboard secondary PWM connector is called pwm2, select the one you connected your GPU to. (trial error) To activate software control you have to go to SpeedFan / Configure button / Advanced tab / Chip dropdown / (mine was the second one IT8620E at $A30 on ISA but for you have to select the one which contains PwM 1 mode, PwM 2 mode etc, ) / select PwM 2 mode and set it to Software controlled. (remember it option on) Temperatures tab / select your GPU / (expand it) / and tick the PwM2, this means PwM2 settings will be triggered via GPU temperatures. Speed tab / select Pwm2 / Set Minimum value set to 0 %, Maximum value set to 70%, this means fans connected to PwM2 only switch on if the temperature is high on the GPU. OK Tick Automatic fan speed and it should change the fan speeds, do a stress test with Intel Extreme Tuning Utility or some Benchmark tools to see if it is working. My setup is: A Dark Rock 4 CPU cooler and three 120 cm Be quiet fan are connected to my CPU PWM connector on the motherboard with a 1 to 4 PWM extension cable. 1 to 4 splitter cable: VanDeSaiL PWM Fan Hub Fan Hub CPU cooling 4 Way Black Sleeved Braided Fan Power Cable 15 Inch for 12V Computer Fans So all CPU, case, and PSU fans are controlled via PwM1. They are set to Minimum 29% fan speed and 50% Maximum, (Automatically variated option on). They are producing 0 dB at 340 rpm so my whole PC is totally silent. Measured with a sound meter sound is between 0 and 1 dB. GPU connected to PwM2 and during web browsing, working, coding etc are turned off since they are not reaching 50 Celsius. There is a be quiet 120 cm fan under my card blowing cold air to it at 29% fan speed. When gaming or video editing and temperature goes above 50 Celsius the PwM2 controller will start the GPU fans and keep the GPU under 78 degrees. My card is throttling at 80 degrees. FYI: PWM fans do not start under 28-29% fan speed. John

My current setup: Strix X99 motherboard Strix 1080Ti AIO cooling my CPU All Noctua fans I'm looking to watercool my GPU so that it runs quieter when gaming, so I've been looking at the EK Phoenix 280 to replace my Corsair H115i and so I can waterblock the GPU. My current setup in my Enthoo case is H115i at the front with 2x 140mm fans pulling air in when the CPU gets warm. The on-board GPU fans are controlled by MSi Afterburner and I also have a couple of fans in the top of the case connected to the extra GPU headers to pull cool air in when the card needs it. + 1 regular 140mm fan exhausting at the rear of the case The mod I'd like to do to my PC is to: Fit the EK Phoenix 280 to both GPU and CPU. Front mount the Radiator to replace the H115i Reuse my current AIO fans plus the extra fans in the top of the case and make put them on the EK block in push/pull. Take the fans that come with the EK rad and put them in the top to act as low RPM airflow for the RAM and chipset (and aid in positive pressure). The question I have is how to set it so that when either the CPU and/or the GPU gets hot, the radiator fans ramp up to cool the loop. At the moment the CPU is controlled by the BIOS and GPU by MSi. Is this something that SpeedFan could do? If yes, I've seen that you can set up different Fan Controllers (under the top tab: Fan Control | Advanced Fan Control) where you can control fans based on different parameters, but if CPU temps are low and GPU high, could the low CPU temp override the high GPU and prevent the fans from spinning up? If you've done this already and it works, would you be willing to share your config and settings? Ta

I have this motherboard: https://www.asrock.com/mb/AMD/Fatal1ty AB350 Gaming-ITXac/index.asp Here is the manual: http://asrock.pc.cdn.bitgravity.com/Manual/Fatal1ty AB350 Gaming-ITXac.pdf I have this pump: https://www.ekwb.com/shop/ek-ddc-3-2-pwm-laing-ddc-3-2-pwm It is now wired like this: Going out to this: So ending up like this on the motherboard (sorry about it being dark): Now this motherboard supports doing this as it says in the manual: Which is what the specifications for that pump are, as listed on the site: And in the manual, it says this: In the BIOS, I have these options: I've switched it to W_PUMP, and set it to PWM Mode, but when I do this, it is stuck at 100% speed at all times. In the manual, it says this: If I choose DC mode, it barely runs the pump at all (10-20% speed I guess). I can hear/feel it running, but it's so slow that my CPU gets up to 50-60C on idle. I want to control this pump with PWM, but it doesn't respond to any settings I give it in BIOS. What are these two different modes and why are they interacting with this pump in this way?

Recently I have discovered that the case fan headers on my motherboard are voltage controlled not pwm controlled. Because the case are voltage controlled they are not able to spin slower than they would if they were PWM controlled. I am wondering if there is a fan controller that would provide me pwm control over the case fans or a splitter/hub that would allow me to connect them all to the cpu fan header. Specs: Define R5 GA-Z170X-UD5 TH (rev1.0) i7-6700K EVGA 1080 FTW NH-D15 with both fans connected to the cpu fan header via splitter 3x NH-A14 ( 2 intake front, 1 exhaust back)

Just upgraded my case and brought 2 new corsiar af120 fans to go with it. I've connect all 4 fans to my Asus strix z270e motherboard and they're still running at 1500 rpm. Which is really annoying. I've went into the bios and put them to quiet mode with the qfan control and they're still at max speed. I updated my bios and still have no results. I also tried using speed fan but I have no idea how to use it. pls help

Hi everyone, I'm just wondering if the fan headers on the MSI H270 Gaming M3 support PWM fans, because I saw in the manual that the sysfan headers has NC on the 4th pin. I just want to make sure before buying because I have 2 pwm fans. Thanks!!

I have a Supermicro X11SSH-LN4F housed in a Fractal Design Define Mini C. The cases comes with two Dynamic X2 G-12 3-pin fans. I removed the front fan. I’d now like to replace the rear fan with a compatible PWM fan but I’m concerned the FAN-0124L4 may be too loud Are there other more quiet 120mm options?

Hello, I'm currently researching a workstation build I'm planning in the Corsair 1000D due to it's dual system support with a headless NAS/Streaming/part time game server with all traditionally controlled air cooling; note no 5.25" bays in the 1000D. As I'm sure many of you are aware there the 1000D houses a huge number of fans. I'm currently stumped on how I can control fan speed on the 8 radiator fans. The rest I can control fine with PWM splitters and extension cables. I'm going to be dual booting Linux and Windows on the main machine and will be booting windows no more than once a month, so would like to stay away from fan controllers that involve software not supported on Linux. It seems ridiculously simple to me, but I've failed to find anything that will do this without a large OLED screen in a 5.25" mounting and a plethora of hardware and software that I'll either never use, or can't run. TL;DR: I have 8 fans than I need to control based on the difference between water and air temp. Is there a product that can take two temperature inputs, calculate a delta, apply a simple fan curve, and generate a PWM signal based on the result? Edit: I should note that I'll be happy with most any reasonable fan curve. Being able to change it is not a requirement for me.

Working on a new build that is using mostly Corsair LL series (120/140) fans and 3 generic'ish 50mm fans on the back mounted over the expansion slots. Am hoping to use a fan controller. I have 4 primary groupings for the fans: 2 LL140mm in front (filtered intake) 3 LL120mm on top for the Corsair cpu radiator (filtered intake) 3 50mm in back (unfiltered exhaust) 1 LL140mm in back (unfiltered exhaust) Id like to group these fans using pwm hubs for the 4 primary groups listed above but I am having troubles finding fan controllers/pwm hubs that are comparable. Does anyone have any recommendations?

My title basically is what I'm looking to do, I know PWM control makes it quite easy to control the RPM of fans, but is it true you can still control the voltage of the fans to in turn get the same result? Is there a program for this? I have SpeedFan installed but I haven't a clue on how to use it. Would buying a fan hub be easier?

Hey guys im looking to pick up 2x 140mm fans. I know I need them optimized for airflow and preferrably I would need them at $15 each or less. I am a bit confused with PWM as my motherboard supports it but i do not know if the fan needs to aswell. My motherboard is the MSI b350 gaming plus, and my case is the Phanteks p400s tg. If you guys have any suggestions on fans that would save my day!
