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

Highly recommended. This is a top-notched product.

I am running two of these on my Noctua NH-U14S in a push-pull configuration along with 3 Noctua NF-A14 PWMs on my case. They are very quiet and my CPU is currently running at 37.5 degrees Celcius.

Extremely quiet!

Have it running with my NH-D15s at 300-500 rpm

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.

Meh. I got it for adding to the single fan on my CPU cooler. I should have gotten 2 of THIS fan http://www.amazon.com/Premium-Quality-Technology-NF-A14-PWM/dp/B00CP6QLY6 to replace my original and add the 2nd fan.

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.

Amazing.

I swapped this into my Noctua D14 for a slight boost in airflow. Keeps my temps way down on my old Intel 980X rig.

Does not come with mounting clips. Just a warning, youll have to contact noctua directly for them if you need
