Are the stock 120 fans pwm ?

They are XtraFlo fans with PWM: http://www.coolermaster.com/cooling/case-fan/xtraflo-120/

It says they are "Xtraflo fans" in the manual and specifications. However, the fans that are actually included with the case only have a 3 pin connector so I don't think this is accurate (as in I don't think the stock fans are the Xtraflow PWM fans). PWM fans have 4 pin connectors with a constant 12 V supply. I was able to get the RPM's down to 300-400 RPMs using my motherboard's 3 pin fan headers, however. Which is confusing because according to the Xtraflo PWM advertised specs, they go only as low as 600 RPM. I know this is a late reply but I feel this is a good thing to note for others wondering about this. It says they are "Xtraflo fans" in the manual and specifications.

I don't think they are. The fans on the Corsair Hydro Series Extreme Performance Liquid CPU Cooler H100i are so that is what I used in this case.

I don't know the max RPM for the stock fans (I didn't even use them; swapped them out with Excaliburs), but I know that they are 3pin (they do not come with a molex adaptor, so you'll need to buy those separately if you don't want to hook them up to your MB or fan controller).

No. The LEDs are always on.Only the front two fans are LED, so you could just buy two 120/mm140mm fans to replace them.

Yes it will. I prefer the 4 pin for the PWM (Pulse Width Modulation) factor. Make sure to have equal speeds on both fans (if push/pull is wanted) use the Silverstone fan splitter. This splitter has one of the pins removed so that both fans run at the same rpm. Try this link for decent fans..good luck. http://www.frozencpu.com/cat/l3/g36/c365/s938/list/p1/Fans-12_Volt_Fans_-_PWM-80mm_x_25mm_PWM_Fans-Page1.html

I received 120mm fans... I ordered 2 of them. They work well and have no issues :)

Yeah, but an after market heatsink is recommended. I bought the Cooler Master Seidon 120v for it.

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.

On both of them that I have no fans were preinstalled I am using Rosewill rfx 120's because I like to be able to adjust the speed also you will need to remove the one top fan if you ever want or need to swap out memory after you have your system up and running.

Yes I have two of them running on a 650 watt PSU along with a liquid cpu cooler so either my PSU is about to blow or these use less power than they need...hope I was helpful!!

Yes any 120mm fan will work. Just make sure you get a fan that moves a good amount of air.

ok-not an electrician-but here is the info on bottom of fan...120VAC 60Hz 0.29A 35W conforms to UL standard.507certified to CSA standard.C22 .2...hope that helps.

Yes you certainly can. Keep in mind the pwm means it has 4 pins. Double check to make sure you get the correct adapter for your needs, you can also get an extension cable (non Y) for fan's as well, they vary in length from a few inches to several feet. Hope this helps.

As far as I know, these fans should fit without any modifications. I haven't changed mine since it's working properly and I'd only consider swapping it for a PWM version (which as far as I know, still don't exist).

I think they are 40MM fans, but in my case, I just unplugged the fans from the board, since I am running all SSD in this unit. But the plugs on the fans seem to be the typical 2-pin type. I agree, a bit noisy, would be nice if they were thermally controlled.

No , this one can only have 2 fans same speed. If you want separate speeds you need Pwm splitter

Yes. I am running it just fine off a 650W PS. Make sure its a decent quality Power supply though.

You'd need 4 200mm, 1 140mm, and 1 120mm color-changing fans. I really don't know about the 200mm fans, but there are 120mm and 140mm Casino fans be Lepa that would serve your needs. The stock fans don't change color, though, so I don't really see how that's a part of this question. You'd need to replace them (it comes with 2 200mm and 1 120mm fans) if you wanted all the fans to change colors.
