Noctua NF-F12 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (120mm, Black)

Its possible that I got a defective unit, but I had 2 main problems:

While searching for fans to replace the stock fan on my Cooler Master Hyper 212 EVO, sitting on an Intel i7-6700K. The lone stock fan just wasnt doing enough when the processor got over 50% load. Lots of research later I found these and went with them over the more common NF-F12 PWM because the NF-F12 iPPC-2000 PWM has a higher RPM, better air flow, and much better Static Air Pressure, all with only a small bump in noise levels. It does use twice the power at full speed but I can accept that if it can keep the CPU from becoming a toaster oven. After the install I did see a 5 degree Celsius drop in idle and light duty usage. When the fresh heat transfer becomes fully cured Ill put it under a heavy load and see how my temps hold up. If things go south, and if I still have a working system, Ill update accordingly. For now Im very happy with them. If I dont update this in the future you can assume everything worked great and no smores were made on the CPU cooler before going all fireball on me. I really like smores but i can build something much cheaper to make those on! Wow, now I might have my Christmas project figured out, now to work out its best system for good results. well its time to take this conversation over to instructables.com.

Setup my first watercooling build and these fans are amazing. Around 1.1-1.2k rpms and keeps my gpu cool at 26c idle on 23c ambient. I ordered the white chromax vibration pads and it’s amazing.

Not sure if I got a faulty fan or not never had issues with Noctua in the past but compared to my Cougars and Noctua heatsink fan this one gives off an annoying buzzing sound. The blades themselves are fine as long as you keep them under 1,500 rpm for an industrial level case fan. Dissapointed.

Very quite, very powerful. I used these to replace my CPU liquid cooler fans. I dare my CPU to get hot now .... honestly Noctua is the best Fan maker.

Loud. Like 60 decibels loud. Be careful

Get a little louder than I expected for Noctua but over all great fans, no complaints other than they did not work with a fan controller I got that only had 2 pins for each fan header. Not sure if 4 pin into 2 pin is a nonbo for 4 pin fans but just beware and make sure you research your fan controllers if youre going to use them with these fans.

Made my SFF PC much more quiet! cannot hear this quiet fan, but the increased airflow allows my loud CPU and GPU fans to run at lower rpms now, super happy with my purchase.

Seriously the best fans you can buy for a PC. Fans are very quiet and move a lot of air.

I am currently using this as the main intake fan for my mini-itx build. Great power and RPM, very quiet and makes everything properly cool to the touch. I run this fan on silent mode just to relish in the emptiness of noise.
