Noctua NF-A14 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (140mm, Black)

These fan do 2 things great push a lot of air and operate at quiet speeds if set correctly.

Bought two of these, and had a problem with one of them. I contacted Noctua and within less than a week, the broken fan was replaced with a brand new one.

I dont know where people get the idea that these are quiet. These are very loud even at 30% RPM. These fans were simply no better than your standard case fans.

I was on the market for a high flowing 140MM fan for my case. I had a 86CFM fan, this one pushes 109CFM. Quieter than my previous fan. If it is too much noise at 2000RPMS, I would suggest just tuning your PWM/Smart fan, or setting the fans to quiet/normal/performance.

These fans move an incredible amount of air through my radiator. Im very pleased with my purchase overall.

Great fan! Thanks #LinusTechTips

They performe well and are only loud at max load which it never runs because the temperatures are not that high.

I used these fans for the first time as replacements for the stock fans of the corsair hydro series water cooler. These fans are dead quiet, move the air, and are in a word SUPERB! If not the best fans out there they are darn close.

Great, quiet fan. Great when used on a radiator.

excellent Fan
