Hey so i wanted to change my case fan control on my bios. I have a z390 aorus ultra motherboard so I went to smart fan 5 in my bios. I tested by trying to turn the fan to the lowest using the curve but nothing happened. I need some help thanks.

Hi guys! As far as I know, PWM and RGB "cables" are the same. I want to spice up my build with a bit of RGB action, and because I do not want to overload anything and for upgradeability I want to get a hub for PWM and my RGB headers. I currently use DEEPCOOL fans (normal, not argb) and I do not need a controller, just a hub. Now I was wondering if there is a difference between a PWM and RGB (12V) hub. And if you had a recommendation? Thanks in advance ^^

Hi! I'm searching for a really powerful 120mm fan but without pwm (with a molex connector for example), it doesn't seems to exist because it would be too loud, but if you know a reference or something like this, it would be really helpful. (I'm doing some experiments with a peltier module and a cpu cooler but because it isn't for a PC, I don't have access to a pwm control board.)

So I recently ordered an NZXT H500i, and I am moving all my parts from my old case into it. However, I am having trouble. The case fan/RGB control hub has a PWM cable coming from it, which I assume would go into my mobo. However, I can't seem to find a single PWM connector spot on my mobo (MSI X370 Gaming Plus) or my PSU (Corsair CX450M). Any help is appreciated, I'm a bit frustrated rn.

I recently bought 6 Lian Li Bora 120 RGB fans. The problem is that I am unable to control the fan speeds even though I have the PWM connector connected. All of the fans are connected to a Lian Li fan hub, which is connected by a molex connector to the PSU and a connector to a PWM header on the motherboard. Motherboard: Asus ROG Rampage V Extreme Fan: Lian Li Bora 120 RGB

Sup, so I want to make my PC quieter. I have some really cheap, loud $10 fans from Amazon right now. Since it's really hard to imagine the noise fans would make, how do you think I'd fair with 4 Be Quiet! Silent Wings 3 (Highspeed, PWM) fans? That'd run me about 80 bucks. The normal speed ones clock in about 16.8 decibels, but the high-speed ones are like 20. I assume I could cap the high-speed ones down to the normal speed and have the same sound. That would offer me more expandability too, so if it's hot, I could set the rpm higher. I'd have 2 intake on the front, one top, and one back - both exhaust. I'd be using these with a Wraith Prism RGB. I know, it gets loud, but I've noticed that's only when it's alone in cooling my pc. If I have my other fans running, it almost never flares up and makes too much noise. So 4 Silent Wings 3 with a Wraith Prism RGB... Do you think it would be nice and quiet? I plan on switching to a Dark Rock Pro 4 or a Cryorig R1 Universal (For the white color) CPU cooler if I want even quieter, but I want to keep my Prism's RGB, so I'd rather not. P.S. I saw a review saying that the frequency of the hum the Silent Wing fans make induces more rage than usual... Any truth to this? EDIT: I'm cooling a 2700x and have a 1080Ti by the way.

So I swapped in some Noctua industrial fans into a Supermicro case while back and I got the PWM 3000rpm model since the motherboard uses PWM through IPMI to control fan speed. The threshold is like 800rpm or something before a low fan speed warning comes on, theres three fan speed settings (Standard, Optimal, Full) and unless the mode is set to full the Noctua fans will not get above 600rpm. Do I need to buy 3pin fans instead?? Would they run at full speed then?

As far as I can tell, in the ASUS x470 bios, under Qfan, there's no way to have 0rpm for PWM fans. What's up with that? I know in Gigabytes Z370 that was possible. I did it for all my fans, even the one's on the aio. The pc was almost dead quiet until a certain temp was reached. Any help would be appreciated. -
Before I start, here are the relevant parts to my issue: Gigabyte Z390 UD motherboard CoolerMaster ML240L RGB Liquid Cooler Fractal Design R6 Blackout Case Manual links: Cooler Master ML240L https://www.manualslib.com/manual/1452876/Cooler-Master-Masterliquid-Ml240l-Rgb.html?page=13#manual Fractal Design R6 Blackout Case (Attached) The wiring diagram from Cooler Master for this cooler is lackluster to say the least, it shows that the pump needs to be connected to the CPU_FAN header, while the actual fans need to use the supplied splitter and be connected to the CPU_AUX header (or equivalent), while all the RGB/PWM 4 pin headers all go to the supplied PWM controller from the ML240L box. I have two questions: 1. Does it matter if I connect the splitter fans to any SYS_FAN header on the board instead? The Gigabyte z390 UD only has one CPU_FAN header, and 3 SYS_FAN headers, and my case will have 5 fans total after the ML240L is installed with the 3 existing case fans. This creates a bit of an issue with header availability, I need 4 headers, but only have 3 for fan support. I could use splitters on the case fans to reduce the amount of headers used, but I don't want to wait for them to arrive from amazon, but I could just leave one unplugged in the meantime, and add it when the splitter arrives. 2. There is a PWM controller mounted inside the back panel of this case. The manual for the case instructs that the power for the controller is to be supplied via SATA cable (there was one nearby, so that was easy), and that the soldered connection from the controller be plugged into the CPU_FAN header. I have attached an image of the specific page in the R6 manual with the schematic for the PWM controller/fan hub. There is a total of 6 lead wires on the Cooler Master ML240L assembly, two from each fan, and two from the pump block. Here is what I want to do: Plug the fan hub connector into the CPU_FAN header, power the fan hub with sata (these are a given), then I want to plug all the Power connectors for the fans into the left side (3 pin) headers on the fan hub, as well as the block pump, and all the rgb/pwm 4 pin connectors into the right side, hopefully bypassing the need for the PWM controller that came with the cooler kit. OR I could use the PWM controller and use the fan hub simply for the fans, and the block pump (3 pin). Hopefully I explained my thoughts clearly enough. If anybody can confirm if what I'm thinking will work, or can help direct me otherwise it would be much appreciated. Thanks! d29f080e-6bef-44b5-a5fb-9e02b8767a29.pdf

I am confused about the corsair icue software. I have 2 Corsair ML 120 Pro White Led fans and I can't figure out how to change the PWM for the fans inside of fans. The fans don't pop up in the software. Do I need one of Corsair's hubs to control PWM?

So I have 3x140mm Noctua ippc 2000 RPM fans rated at around 107cfm each on front intake, 3x Bora lite 120mm fans in top exhaust position rated at 54 CFM each. 1x 140mm rear exhaust fan rated at 82 CFM. I'm wondering with all this intake pressure (avg 275 CFM) from high end fans, should I swap in my two 140mm fans with higher CFM in top exhaust position? And uninstall the 120s? I was aiming for equalish pressure and even with aggressive fan profiles on the exhaust fans I'm not even within 100 CFM of my intake pressure. Seems rather unbalanced IMO. Additional Technical Data: Static pressure of above mentioned fans are: 4,00 each for the 140mm front intakes x 3 Around 1,06 each on the 120s x 3 And 1,86 on the rear exhaust fan. 1x Case is Phantek Evolv X I could alternatively swap in two higher CFM 140s in top position or crank up my 3 120s, or just replace my exhaust fans with all higher CFM variants. I like to keep my intake fans up pretty high for static pressure case restrictive reasons, that's why I'm concerned with having too much positive pressure in this scenario. Suggestions are appreciated Thanks as always

I would like to utilize a few of the fans (140mm Phantek SP) that came with my chassis. (Evolv X) But if you determine there's a conflict with VC/PWM I'll fit all PWM fans. I purchased three Noctua 2,000 RPM 140mm ippc fans for front intake which are the 4-pin PWM variety. The Phantek SP fans aren't terrible but they are 3-pin fans. They will be positioned for top exhaust. I'm utilizing a Deepcool FH10 (Ten-Port) PWM fan hub in this build. Can I hookup my PWM fans and voltage control fans to one Deepcool PWM fan hub and have speed control on the non PWM fans as well? Would it be wiser to utilize the case's fan hub (rather sub-par but has a few three pin connections) for the 3 pin fans, and use my Deepcool unit for solely the 4-Pin PWM fans? Motherboard is Asus X470 Hero VII. Thank you!

Looking for high CFM, good RPM and excellent static pressure high-end 4 pin PWM controlled fans (not concerned with sound levels) for the somewhat "airflow deprived" Phantek Evolv X chassis. All help is appreciated

Hello, I have a rosewill cullinan v500 case (3 fans in front 3 fans on top and 1 fan at the rear) and I also have a 360m radiator in front with 3 fans running on case fans (fans that can't be controlled by software or temperature in my pc) I would like to change the 3 fans in front in to PWM fans and would like to know where I'm going to put them on the motherboard? I want them to sync up with Q-fan I have a Hero XI motherboard so that when my cpu gets hot fans would spin on a higher rpm. I also have the top fans as exhaust and the rear one as exhaust. I would like to switch out all 7 fans with PWM 4 pin fans but I just dont know where to place them all Individually or using a splitter. Any help would be appreciated. Thank you in Advance!

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?

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?

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)

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!

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

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?

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.

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. -
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 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?
