NoctuaNF-F12 iPPC-2000, Heavy Duty Cooling Fan, 3-Pin, 2000 RPM (120mm, Black)

I purchased 3 of these and my PC is significantly cooler as a result. I cannot recommend these more! Easy to set up, easy to modify the settings in BIOS (such as fan RPM).

Works perfectly as a replacement fan for Drobo 5N. Its a 3 wire non PWM, so uses just the 12v black and red wire and runs between about 5v and 12v according to the signal from the Drobo board. Took about 30 mins to swap into the drive. Has a different pin connector, so a splice with the original connector is needed.

Because this fan is designed to move relatively large volumes of air it isn't as 'silent' as other Noctua fans, but nevertheless it is very quiet. I'm very impressed

Just what I wanted, hope it lasts years

Nice quiet reliable fans for my server rack at home!
