I've heard this unit has trouble with the PWM signal. Anyone using 2-4 of these fans on a single MOBO fan header (with splitter) have any issues?

I use the PWM splitter from Swiftech with these fans and haven't experienced any issues. I am running 5 or so of these fans for my water cooling setup.

No I have 4 of them on my 480 radiator and have no problem I use a molex to 4 way pwm splitter
624167
I have no issues with it and 4 of them are connected to 2 fan headers using the silverstone pwm splitter. What specific issues are you referring to?

I've got 4 total, 2 per header. 2 on intake and 2 on exhaust with no issues on speed control.

Sorry, I'm using fan controller. I don't recall how many amps the MB header will handle, but that might be an issue for some if using just one header for all. Check out this thread, it may help. GL! :) http://forums.evga.com/tm.aspx?m=2012030

I stuck with the stock fans and they've worked for me - quiet, no overheating. That said, I should mention that I'm not overclocking anything in this build and did the best I could to keep wires out of the airflow channels (cable management is still a challenge in this form factor, but if you're doing it for cooling and don't care what things look like once the case is closed, you're fine). I'm running an i5 4670K with stock heat sink/fan, Corsair Vengeance RAM, 2 x 2TB hard drives.

These fans aren't PWM controlled, so you would need a separate fan controller. If you would rather have PWM fans they aren't much more in price than non PWM fans, you should be able to find some cheaper than these.

i have the same fan,,this is not normal,,i would send the fan back,,i have no noise in any speed or operation from this product,,i have been thinking about getting a second one,,,sorry to hear your having problems.

'course! I've not had that issue with this case buuuuuuuuuuuuut there's a few things we can do!Firstly, make sure all the power cables to the fans coming from the case are connected to MOLEX/4pin power connectors (or the relevant ones for the fan you are connecting) and if it's still not receiving power and spinning up either A) Send the case in for replacement or B) Try a replacement power cable to the fan.Not really much more help beyond that which can be offered I'm afraid!

All 4 pin connectors support 3 pin fans but the PWM speed control is not supported (4 pin PWM fans only). This board has two connectors for case fans and one for the CPU. Personally, I'd spend a couple extra bucks and buy new 4 pin fans.

I have 4 of these on a H100i and haven't had any problems. You should return it and get a replacement. There is always a chance that a part will be defective. It is just how lucky you are. Corsair is still the way to go. These fans rock. Or the CoolerMaster JetFlo

The one I got booted up fine and was nice and quiet during idle on the desktop. But load up an intensive game, and the fan was very noticeable. I could hear it from outside the room, down the hall, and downstairs. I returned this M12II and got a Seasonic X-850 GOLD Seasonic X-850(SS-850KM3 Active PFC F3) 850W 80 Plus Gold ATX12V/EPS12V Power Supply instead, and have been happy with it for the last 2 years and counting.

One Fan. the PWM splitter only has one of the two connectors connected to the 'signal' of the pwm fan, so if both of your fans are the same, they will be running nearly identical speeds, but you can't control them separately.

Yep should be just fine. I run SP120s and AF140s in my case (2 fans per channel) and I hooked them all up to single channel on the controller for awhile so I could test the mosfet temps. Didn't run into any problems with 5 SP120s/AF140s on the same channel.

Mine works well, fans are very loud. They sent me replacements haven't installed yet...

Is there a solution out there that allows independent signal flow and speed control through fan splitter cables? I sure hope so..

One fan. Furthermore, any PWM splitter is only going to be seen by your motherboard as one fan as only one of the connectors will be wired with an RPM wire, while all will have GND, +V, and the sense wire to control fan speeds. Any non-PWM(voltage controlled) splitter will only contain RPM on one fan and GND/+V. If you want to see individual fan speeds you will need to use individual ports on your motherboard or fan controller.

I have the 4 wire(pwm) 3.90 amp Delta fan, and I cannot slow down this mega fan enough to be usable, with this controller. It works great with my other non PWM fans but I can only slow this Delta fan about 1/8 before it just shuts off. If you have gotten the 3 wire 3.9 amp delta fan to work properly with this PWM speed controller, I'd like to know.

I don't know what PWM fans are but as far as I know as long as your fans have the right # of pins all you do is plug them in to the control box and your are set..to set them the way you want then is easy, just follow the directions..i have had mine for a few months and no issues.. love this thing !!

Oh, and do a push pull configuration with that hearsink and youll never have issues. I also recommend arctic silver thermal paste(one fan pushing over the heatsink, and one fan pulling and exhausting. Both fans will blow the same way)

What I did was open the case and take the guts out. I ported them to a case with a 120mm fan. I had to solder a bit and it was a pain in the butt. The PSU is decent here but it sounds like a jet engine. Mine had TWO 80mm fans. Insane. Now I have one decent, quiet PSU. Another option is to simply unplug one of the fans - unscrew the back and unplug the intake fan (facing the Mobo). You probably want to leave the exhaust fan intact.
