I'm looking at purchasing a new motherboard and I've had my sights on the Asus Z97 Pro-Gamer for quite some time as it's not as overkill as the Rampage boards but it has some extra features compared to the Z97-A without breaking the bank. So my question is two fold: I'm going to be switching to liquid cooling and I've read/heard that it is highly recommended to plug the pump into a header (or directly to the psu) that would provide 100% power at all times as opposed to plugging the pump into the cpu fan header where it would be controlled depending on how stress is on the cpu. Rather than getting an adapter to plug the pump into the power supply, I was wondering if the Chassis fan headers (CHA_FAN) on the asus motherboard are PWM like the cpu header or if they supply 100% all the time. I've tried searching around but I was unable to find anything conclusive. Any help is appreciated, thanks.

I was planning on doing a custom loop with a 240mm rad and a 140mm rad, the loop including both a 4690k and an R9 390, is it safe to run the pump and all three fans off of the CPU header on the motherboard using a simple 1 to 4 splitter?

I recently purchased 5 Noctua NF-A14 iPPC-3000 PWM fans to use in my Corsair 750D. I have a GA-990FXA-UD3 motherboard which has 1 PWM fan header. So I purchased this Swifttech PWM splitter to connect to the PWM header and run the fans off of it. The problem I have is that the speed of the fans never seems to change they run around 2500 - 2700 RPM at idle or under load. My CPU temps are never getting above 47 C. Checked the BIOS and changed the fan control method to PWM from Auto and it still didn't help. These things are loud as crap so any help on how to slow them down would be appreciated.

Hi guys! I am in the process of building a new PC and everything seems to work fine except for one pesky issue. For the life of me I can't make Arctic F12 PWM PST CO work. My mobo (Asus Z97M-PLUS) has a CPU fan header which works just fine and two Chasis fan connectors - and that's where the problem is. The fan comes with 4 pin + 3 pin plugs and 4 pin socket. According to manual if I only want to connect one fan I need to connect 4 pin plug into mobo header and create a loop by plugging 3 pin connector into 4 pin socket. Which is what I did. But the fan simply refuses to spin (not stuck, just no signal). I tried both 4 pin headers, with the loop or without it - nothing seem to matter. In BIOS both CHA1 and CHA2 readings are unavailable. I tried to enforce PWM mode, but it does nothing. CPU reading is fine and the fan works. The BIOS is relatively new (2801). So, should I update to 2802? Is the fan bad? It's unlikely that both headers are bad, thus I am not considering this as an option atm. Would be great if you tell me it's just me being an idiot and missing something trivial. Thanks in advance for any help.

Hi everybody! I posted this in Troubleshooting, but looks like I messed something up because there's no views (and hence no answers) in the thread. Sorry for double posting.

Hello, and thanks for reading this already! I'm looking for some Quiet, White Led, PWM fans. I was looking at the Bitfenix Spectre LED PWM, but there's a lot of discussion on how good they are. Are they solid, or are there better alternatives? Thanks in advance!

I want to use the Swiftech 8-way PWM Splitter-SATA I have these fans but they are different RPM! 1xCPU QF120: RPM 330-1600 3x Akasa Apache black 140mm: RPM 600 - 1300 How would this work? Has anyone of you deal with a situation like this? Would it be fine?

I would like to know from you guys, which are the best PWM fans for radiatiors, and cases in general. I've heard that Noctua is the best. But, too expensive. I'm looking for similarly performing cheaper alternatives to the Noctua NF-F12, but they must be 140mm fans. Please do post your opinions on your suggestions for the Top 5 140mm High-Static PWM Fans. Thanks!

I have a BeQuiet 120mm case fan which is quieter than my Coolermaster 212 evo fan. I was wondering can I swap the fans around? The BeQuiet fan only has 3-pins and isn't pwm however the Coolermaster is. Will this be a problem? If so can I overcome it with bios settings etc?

how does the fan hub in the NZXT h440 work does it just run the fans full speed or is it connected to the motherboard for controll???

I have been looking for a way to control my Antec 900's case fans beyond the simple 3-way switch... primarily to enable my motherboard's ability to shut the fans off completely in very low loads. (is this even a good idea?, CPU fans will still be turning & GPU fans. I have haven't been able to find an adapter yet and I am wondering: Does it exist/ is it even possible? Thanks for any help you have, and I'd appreciate that the adapter be black.

Ok, so here's my setup. I'm using an Cooler Master Elite 110 case, which has a 120mm fan in the front. I'm using the Corsair H55 AIO cooler for my CPU, putting the radiator at the front of the case (which is the one 120mm mounting spot on the case). Right now I'm using the fan that came with the radiator, but it's a 3-pin fan. Because this PC is being used as an HTPC, idle noise is a concern. Under load, the GPU fan is certainly the noisiest part of the build (which is expected), but because there's no speed control on the front fan, it becomes the loudest part of the build when idle. I'm thinking about replacing it now with one with a 4-pin connector so that it can ramp up and down with the system load. However, I'm not entirely sure what to look for. Right now, the Noctua NF-F12 iPPC-2000 PWM seems like a good choice (it has the PWM control, and has the power to actually push air through the cramped case) at $23 on amazon. Is there another fan I should consider? Is it even worth it to replace the fan?

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?

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

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

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 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.

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 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 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, 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

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 everyone, I was using my computer earlier and noticed my GPU fans weren't spinning. I went into MSI afterburner and indeed the fans were all set to 0. I changed the speeds manually and it seemed to work, however whenever I put it into auto mode. they just stayed at where I last set the fan to. I then shut down the computer and checked to see if the PWM fan was connected all the way to the headers which it was. Then, upon switching the PSU back on and then pressing the power button, the GPU fans spun for half a second. With an audible pop, hiss, and then a puff of smoke from the PWN wire with the wiring looking like it spit open (which upon inspecting it did) my PC shut down. Which now leads me to believe my GPU is dead, however somewhere in my mind I doubt it. What do you guys think? I've never had this happened to me before and was wondering if I can still salvage my card. Which is by the way an MSI 290X with an Arctic Accelero III aftermarket cooler. Any input and help I can get would be greatly appreciated! Attached is what the PWM wire now looks like
