Customer Reviews

Alienware Aurora PSU Fixed


My 2010 Alienware Aurora R1 was beginning to sound like a Hoover. Replaced all fans with Noctua units using this one in the PSU. BIG difference! Wouldn't know it was switched on now.

Quality system fan


I bought this fan to replace my system fan along with a new CPU fan, after the initial upgrade I found both worked perfectly well, the system fan was working in conjunction with the CPU PWM fan, as the CPU fan speeds up so too does the system fan, even though the system fan isn't PWM, I cannot fault this fan or the other, excellent product's providing whisper quiet operation, I will never use any other, they are not a marketing gimmick, they really are that good.
