ok so on my asus mark s i have some free fan headers and i want to see if i can use the pwm to dim leds by making my own fan curves on my AI suite. before you say that the MB doesnt have the power, each fan header can supply 1A roughy, and running a few leds WONT get even close to an AMP of power draw. and i can always use a led amp to power them and just the pwm to control them. has anyone done this? and yes i know about the nzxt hue and corsair link leds... and i dont like either. im looking for something i can really tune by hand while inside my os and even by wifi can i simply take the pwm and ground from the 4 pin and run it to the + and - of the strip to get power? -
Hi guys, I will buy my new gaming PC in few weeks and my case will be the phanteks enthoo pro and my mobo the MSI Z97 Gaming 5 I was wondering if the cpu_fan2 connectors of the mobo is a true PWM signal modulation? Because I want to use the hub fan connectors of phanteks (to plug all my fans, except the cpu cooler), and I want to be sure I will control them like I want, and not just with voltage (like 3-pin fans). Thanks.

Hi, I have a Fractal Design R5 case with an inbuilt fan controller with 3 x 3 pin female fan cables coming out of it, I just bought a noctua PWM fan with a 4 pin male fan cable. I bought it because i didn't think it mattered since you can connect 4 pin fans to 3 pin motherboard but I just figured out that the 4 pin male cable does no fit into the 3 pin female cable. My question is, are there any adapters I can buy, I looked in Amazon but I couldn't find any, it just gets me a bunch of molex to 4 pin adapters. Thank you

Hello guys! I have a pc obviously and i have a very serious question! First of all my specs are: CPU: Intel Core i5 4670k 3.6GHz GPU: ASUS GTX 760 DirectCU2 2GB GDDR5 RAM: 2x4GB DDR3 Corsair Vengeance 1600 MHz High Profile MB: MSI Z97-G43 My motherboard has 3x4pin system fan headers and 2x4pin cpu headers Searching the web i have noticed that only the 4pin headers are able to change the rpm of the fan! But the thing is i have 1 intake and 1 exhaust fan (3pin) and i can actually control the rpm from the UEFI. Anyway the problem is, i am buying 4 more fan (excactly same as the other 2) and as you can allready tell i only have 1 header left! Today i found some BITFENIX 3-PIN to 3x3-PIN ADAPTER sleeved cables (excactly what i want as i am gonna use one to plug the 3 intake fans and the other one to plug the 3 exhaust fans) I want all the intake fans at the same rpm and all the exhaust fans at the same rpm again! For example. Intake Fans 1,2,3 600rpm at idle and 1200rpm at gaming situations (everything controller by the pc itself as it is now with the Intake Fan 1) and Exhaust Fans 4,5,6 700rpm at idle and 1300rpm at gaming situations (again everything controller by the pc itself as it is now with the Exhaust Fan 2) 3-PIN to 3x3-PIN adaptor : http://www.eshopcy.com.cy/bitfenix-3-pin-to-3x-3-pin-adapter-60cm-sleeved-black-black-p-PER.640818 6 Fans: http://www.eshopcy.com.cy/bitfenix-spectre-pwm-120mm-fan-black-p-PER.641133 And finally the question is: Having these adapters will let me control the rpm of the intake and exhaust fans? Or my pc will take off and waste my money? I know that, if i am able to control the RPM, all the fans connected to 1 adapter must have the same rpm but that's not a problem for me! Please answer as soon as possible! Thanks in advance!

So I'm working on prettying up my computer (Hence my earlier post about a white led fan) I currently have a Nepton 240M with 4 fans on it pushing air out the top of the case. I want to change this to an H110i GT and give my friend the Nepton to replace his stock cooler with. I currently have a pair of F-A14 industrialPPC-2000 IP67 PWM fans from noctua as my front 2 intake fans. I was thinking to get another pair for the H110i GT. I know these fans can turn into Computer Jets if you want them to but would they be good as my radiator fans to be taking air out of the case? I really like these fans because of the black and anti vibration pads. I'm a bit of a quiet freak at times so I was hoping to keep these running minimal while the computer is idling. Does anyone know how these perform on a radiator? or of any better 140mm fans for a radiator? (To summarize my wants) -Quiet -Black -Good for radiator (High SP) -PWM -140mm

Recently i completed my new rig, which includes a NZXT Kraken X61 cooling a 5820K. I replaced the stock X61 fans with Noctua NF-A14 fans (2, in pull configuration). Temps are great, around 50 stressed running at 4,25GHz. However, the PWM control of the Kraken X61 doesn't seem to work properly, as according to the CAM software, the Noctua's are running at 1900 RPM at 25% fan speed, jumping up to 1980 at 100% fan speed. It's impossible to hear a difference between those two levels in sound. Am i missing a setting in the CAM software? -
Sorry if a i am in the wrong section for this topic, I am in a dillemma here about which of the two fans i am gonna use on my triple 45mm radiator for my custom waterloop of my first build.So i am concerned about: 1)the static pressure of the fans 2)the noice level compared with the rpms which affects the efficiency(the static pressure) 3)the looks of it. I am looking for the best combo here.I think i gonna propably run them from 700rpms up to how knows but not above 1500 as i can imagine but i would to have even more rpms avalaible and not to buy one with 1400rpms limit.The theme of my build is primary red and black with a little blue (of the corsair 850i) and with white leds. So the two candidates are : http://www.coolermaster.com/cooling/case-fan/jetflo-120/(Coolermaste Jetflo 120mm PWM,red led) http://www.akasa.com.tw/search.php?seed=AK-FN072(Akasa PIranha 120mm PWM,blue blades) The fans are going to be placed in a dark place in my case along with the rad so if i don't put led strip the won't be seen unless i use the jetflo which has led. The prize in my region is exactly the same so no budget differences. I read and saw in reviews that the akasa is pretty good with low noice to efficiency ratio but in my opinion not looking to good as the jetflo which is being told to be louder. So any advices or observations to help me sort this out? P.S. Sorry for the long post

Howdie! I will have 5 radiator fans which I want to control with just one motherboard header! Is there any splitter cable or small splitter pcb out there, which has pwm readout from the first fan? Of course it can also be more than 5 headers but 5 would be perfect! AND it should be fairly cheap!

Looking at this motherboard for mATX build http://www.asrock.com/mb/Intel/H97M%20Pro4/ In the spec's it says "multi-speed control" for fans and temperature sensing n stuff like that. I wanna know if i can manually dial in an rpm for a fan to spin at. My fans will be plugged into the motherboard headers not the power supply so I should have voltage control but I want to make sure because I love having all fan mounts used but also like a silent system so if I could chuck em all at around 900 rpm that would be sick. Thanks ^.^ -
Ok, so very soon I will be starting a new build with the MSI Z97 Gaming & Motherboard. So far I am super happy with the board itself, and the only concern i have is the way it controls fans. What i want to be able to do is to connect a NZXT Grid+ to the board, and have it run six Corsair SP120 fans for my 2 360mm Radiators. Then i will be running two 120mm front intake fans from the board as well as a single 140mm exhaust, so i have positive case pressure. I don't have any issues with the rad fans, as they will be running off of the Grid+. I don't want to be doing any overclocking for any of the gear in my system, so the water cooling loop should be fine to keep things cool. My question is about the fan headers for the 3 case fans. I will be using all Corsair fans, and none of the fans that i have chosen are PWM, they are all 3 pin. I know that its ok to plug a 3 pin fan into a PWM header, but i have a concern. The problem i have, is that i want to make sure that if i do plug a 3 pin fan header into one of the boards "case fan" headers, that i will be able to control it. I don't want it just running full speed all the time, and i really want to be able to make the two intake fans and one exhaust fan speed up and slow down by the temperature of the components. Over the internet i have heard that if i plug the 3 pin fans into PWM headers that they will run at full speed, all the time. but i haven't been able to nail anything down to this board specifically. If i plug 3 pin Corsair AF series fans into the "Case Fan" headers on the MSI Z97 Gaming 7 will i be able to set them to turn up and down with temps? Also, can i just set the fan curve to auto and not mess with it? I don't want to have to mess with making a fan curve, and i would just rather it be done automatically.

Hi! So my motherboard will be the M5A99X EVO R2.0. The case will be the Corsair SPEC-03. The cooler I will be using is the Hyper 212 Evo. Here's what I know about them. My understanding of PWM fans is that they control their speed based on the temperature of the computer. They also turn off and on very rapidly to change the voltage going into the fan therefore changing their RPM. Are the PWM fans only for CPU coolers? Normal 3-pin fans, however, just go on full speed. Am I right? The Sickleflow fans have an included 3 to 4-pin adapter. Will that adapter allow me to make it PWM fan? If not, whats the purpose of it? Is that 4-pin adapter just a molex adapter? Are there such things as 3-pin fan headers? Will the fans go on full speed if I just leave them on any fan header? Should I just get a fan controller to control the 3 pin fans? Thanks and have a great day

Hey everyone i got a small problem figuring this out. So the thing is that i am gona put a 3ple rad with 3 fans on my system and i want to control the fans individually or at least the rad fans as a pack.But i got 4 extra fans in my system for good airflow. So my mobo has CPU_FAN and CPU_OPT 4pin headers and on of them is going to be used for the pump.And CHA_FAN x 3 4pin headers. If a use a pwm splitter like this : http://www.ekwb.com/shop/accessories/cables/ek-cable-splitter-4-fan-pwm-extended.htmlwill i be able to control each fan connected to the splitter individually as it is claimed on the specs of the splitter.Beacause if i am gonna connect the 3 rad fans and one other fan of the system to the splitter i want that fan to be controlled apart from the 3-rad-pack. If this isn't my solution what can i use instead?A fan hub would do the job?LIke phanteks or Grid+ from NZXT? Ideally i would like a fan hub so i can upgrade my system with a second 3ple rad and control again the 3packs individually. Thanks for helping me sorting this out. p.s A fan case control solution is not at the table right now due to budget problems . p.s2 All the fans are pwm right now but non-pwm solutions are acceptable

I stupidly put my faith in Corsair Link for the past few years, and while it worked fine on my old build, it's giving me nothing but headaches now (loading profiles wrong, duplicating items, etc...) It sucks, but that's apparently not news. I'm looking for the following: -Control a minimum of 8 fans (4x NF-A14 iPPC 2000's, and 4x Rad Fans (which will soon be something new, maybe Vardars?) -Be able to create custom curves on all 8 fans according to CPU temp -Software, or a hardware solution that is RELIABLE. Although I'd prefer hardware, something I know I will set once and be able to forget about. I do have two 5.25 bays available. -I'd really prefer to not use my motherboard's fan headers (for one, there isn't enough), and I'd like to keep as many cables out of my main area as possible. Any suggestions you have would be hugely appreciated.

Hello, and thanks for reading this already! So, for a friends build, I'm looking for a 120mm PWM fan, which is static pressure optimized, and is cheap. Quite a bad combination. Thanks in advance!

Hello, I have hooked up the GPU fans of my R9 290 trix to my motherboard as I wanted to get quieter idles ( hopefully switching off the fans at idle ) , I have hooked them up but the minimum RPM is still too high ( 1500RPM ) Is there a simple way to lower the speed ? Undervolting and still using pwm ? I tried a 12->7v adapter , but it got very hot and didn't help.

Hi, so I bought an Asus X99-A motherboard, and the manual talks about a fan extension card sold separately. I'm trying to find a place to by one other than sketchy ebay vendors, but so far I've come up empty. Does anyone know where one might be available from a non super-sketchy place?

Hey! So I recently bought some new fans which only had 3 pin connectors to go either side of my Coolermaster TX3 Evo, instead of the provided fan, which had 4. Every time i boot my PC up now it claims there is no CPU fan connected, even though the one 3-pin fan is in the CPU fan header. Any pointers on what to do in the BIOS to prevent this problem from happening (some kind of PWM > DC change maybe?) Thanks, Rhys
-
So I use a corsair H110 cpu cooler with two 4-pin fans. I would expect that in BIOS I should control them with PWM, but they seem make a pretty annoying noise when on PWM compared to DC control. Would it be too wrong to control their speed with DC power? Thanks!
-
Hi guys, I have a dual tower cooler and would like to run both fans PWM but the motherboard only has one PWM fan header. Should I wait for a fan splitter to be delivered or should I just solder the fans together ? I know I should not solder all the wires as the PWM will not work. I also know that the fan header can output to 1 amp and the fans are 0.25a so running two should be fine.

So confused about what fan to get. Need to buy them tonight. Must handle being behind a dust-filter. Want a fan that at full voltage (100% PWM) pushes some air but isnt loud. At 50% PWM is dead silent. Must be able to handle dust filters too. Problem is I have no experience with any of these fans other than youtube videos... Here's what Ive considered & my thoughts: NF-F12 PWM seems loud in videos NF-P12 PWM seems quiet but less CFM than F12 NF-S12A PWM high CFM & only wind noise, but dies behind filters Vardar F2 PWM Gentle Typhoon like; slightly louder than GT COUGAR V12HP pushes more air than GT but is louder So what shall I get? NEED ANSWERS ASAP & THANX!

Hi, So here's my situation: I'm looking to invest a bit into proper (more silent cooling), since my system is quiet powerfull (or atleast powerfull enough for my needs) but not exactly silent. So I was going to buy some NF-F12s for my case and some NF-A14s for my H110 CPU cooler. Where I live the PWM and the 3pin-version are almost the same price (currently €19,84€ for the PWM and 19,58€ for the 1200RPM 3pin version) (thats for the NF-A14, I beleive the prices for the NF-F12 are simular (in regards to the price diffrence between PWM and 3-pin) 1. Now here comes my actual question: If I was going to just buy all fans in their PWM version and just plug the ones for which I have no PWM headers on the motherboard left into a regular 3-pin fan connector, would those behave like any ordenary 3-pin fan and would their 12V speed equal the maximum PWM speed(in this case that would be 1500RPM) and could I also control them over a fan controller like any regular 3pin fan? I'm asking since the price diffrence of a few cent really doesnt matter to me and if I get more versitility for future changes on my setup by buying the PWM versions that sounds great to me. (if they behave how I think/hope they do) 2. A quick side question about NF-F12s and NF-P12s: As I understand it the NF-F12s are the Airflow version for case ventilation and the NF-P12s are the static-pressure version for heatsinks. Please correct me if I'm wrong! 3. Finally about my setup: I was thinking of running the Pump of the H110 and 2 NF-A14s over a PWM splitter from the 4pin header labeled as CPU_FAN I was going to run all the other fans (2*200mm and 1*230mm (which came with the CM HAF X case) and one additonal 120mm rear exaust over a fan controller so the run nice and quiet) I have 2 more motherboard headers: One 3pin labeled PWR_FAN and One 4pin labeled SYS_FAN2 (which I wasn't going to use since I was going to run all the other fans over the fan controller) (for some reason there seems to be a SYS_FAN2 header but no header labeled as SYS_FAN1, seems kind of odd and random to me) Is this a good idea of pluging in the fan-cables that way or does this sound like a terrible idea and I should for example also use the two other motherboard headers as well? Thank you in advance for any insights you guys might give me on this topic ...and I hope I didn't post too many questions for one thread.

I've never made a topic here on LinusTechTips, but I assume it's best if I just try and get right into the problem. About two months ago I bought a Noctua NF-F12 static pressure fan for Cooler Master Hyper T4 cpu cooler. For the first month it was really quiet, all i could hear was air whooshing through the rad. I bought a compressed air can to clean the dust out of my pc, sprayed all the fans, including the Noctua, but when I turned it back on, at around 700 rpm and above it started to make a slight whirring noise, one that I haven't heard from the fan before. Could I have damaged the motor or fan bearings inside to cause the new whirring from the fan? I was thinking it may have loosened from the motor when i sprayed it with the compressed air. Also, if there's anything I can do to possibly fix this, then let me know. Thanks!

If im gonna replace the fans on the nzxt kraken x60 which fans should i use? Noctua NF-A14 PWM or Noctua NF-A14 (non PWM)? (All fans are from the IndustrialPPC-2000 lineup) Im replaceing the fans cause the white color does match the red and black build.
-
Hello, and thanks for reading this already! This is maybe (probably) a stupid question, but can you use normal, 3 pin fans in a fan controller? Please don't hate me Thanks in advance!
-
I'm aircooling my PC right now and am slowly upgrading it to water cooling. So, I picked up some of the fans I'm interested in using. The only issue is the Corsair 780t built in fan controller runs them way too loud on the lowest fan setting. I believe the controller sends 5v on the low setting. So, is there a splitter or fan controller that is safe to run these on without blowing out a header. I'll probably have about 15 of these in the case when I'm done, with 12 on radiators. I'll probably need to pickup two controllers or splitters. I did notice on Noctua's website they suggest against using most common fan controllers with these. Anyone know how to safely manage the speed of these fans? They're just unbearably loud right now.
