Considering a fan-swap for my Corsair HX520

Post by bozar » Thu May 13, 2010 2:28 am

Been trying to quieting down my already semi-quiet rig and with undervolted Nexus fans suspended HDDs and a undervolted [email protected] Ninja 2 I guess it comes down to the PSU after covering the upper fan position in my P182.

The fans I've been considering are S-Flex SFF21F for low starting voltage and max 1600 RPM (should provide adequate cooling but will it be quiet enough and is 4V low enough for a PSU?) and Enermax Magma 1500 RPM for good acoustics in the Eco80 500W review (low starting voltage but is performance good enough to prevent overheating in a older Corsair PSU?).

My idle [email protected] wall socket stays at 80W and I never use Prime95 or similar anymore but with heavier load during mixing sessions it tops at 150W at most so there shouldn't be much of a heat issue.

Would really appreciate some input here.

I've put this fan in my previously somewhat noisy Zalman 600W PSU in my P182. With rubber mounts, I don't hear it.

S-Flex F is perfect for this PSU. I swapped one into my HX620 after the stock fan developed some chugging sounds. Quiet as ever, no worrying about the Sony fluid bearings. 150W load is nothing on this PSU.
