I just replaced a bunch of 120mm fans with these.
Love it work as expected and very quiet.
I would love for your company to send me some more so that I could review them to friends and use them in more of my computer builds in the future!
Great fans, very silent and with good airflow!
I now have three of these in my system (plus the other that came with the CPU), and it is still barely a whisper of sound coming from the case.
It may do the job, but it is extremely noisy.
For the price, it wasn't worth the hassle to return.
