Noctua NF-A15 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

This fan is quite and has a lot of power of moving air. It 4 pin (pwm) fan makes it excellent for it to be attached to the mobo if you dont have a fan controller.

Bought 2 of these to use on my CPU cooler, an NZXT Havik 140 that goes with my Intel I5-4670k. Yes I am using a cooler and CPU that is 6 years old because Intel has been slacking for years, and/because AMD was irrelevant. Luckily AMD is on fire now and their 7nm is coming, so is Intels very late 10nm. Until then the Havik+I5 combo soldiers on and the two 140mm fans that it came with were dying.

Everything as described. Only thing I wish it had was another attachment for CPU cooler. Luckily the NH-D15S

Quiet, subtle, and efficient. Worth the premium over other fans.

I bought this particular fan to replace the fan that came with my Corsair H55 Quiet Edition liquid cooling kit. The stock fan on that thing was super loud...to the point of obnoxiousness. I have a mini-itx case that included a spot for either a 120mm fan or a 140mm fan. For the best airflow, I knew Id want to go with a 140mm fan...but unfortunately, you cant hook up a 120mm radiator to a 140mm fan. Or so I thought.

Quiet!

I replaced a stock Cooler Master Hyper 212 evo fan with this one and its just so darned quiet. It never revs up past 1100 rpms. Keeps the ole FX 8320 down to 51c at max usage. It barely fits in my case so make sure you have enough side clearance to get it in there. Also, youll probably have to use RAM slots 2 and 4 cause your first RAM slot will get gobbled up by this quiet cooling monster.

Does not work well in my PC.

Super quiet, a little big but the noise level is excellent and the performance is extraordinary.

Not as powerful as others, but is silent and cooled my CPU by some digits
