[SOLVED] SP120 Red Led not running at rated speed.

[ron2456]

Hello my newly bought CorsairSP120 is not running at its rated 1650RPM as advertised on Corsair's website.
I have attached the screenshot from HWinfo. All are connected to Mobo headers

Here is the bios screenshot.

Unless there's something wrong with your fan curve in BIOS that's still totally within the typical +/- 10% rotational speed variance that fans have. Corsair doesn't advertise it, but if you look at say, Noctua's fans, they all show +/- 10% in their tech specs.

Is the fan mounted at the top of your case? Those are sleeve bearing fans and they really don't like being mounted horizontally. At work we had a 50% failure rate after 1 year on the top exhaust fans of our Maingear workstations. I always recommend spending more on fans because you only have to have replace a failed cheap $10-12 fan once before you've spent as much as you would have on a good $18-25 fan. Noctua has insanely long minimum time before failure ratings(17+ years of continuous use.)

Also, HWMonitor sucks. Use HWinfo64

Nope, its front intaje fans infront of hdd cage

Well, +/- 10% RPM would be 1480-1815 RPM for that fan, so there's nothing unusual there especially since it's not PWM.

Also do you think using the case without front filters is wise? My front filters came loose and the pressure of fans is pulling it towards them.

You'll just have to clean the case more often. Really heavy dust buildup on fans can make them unbalanced so they might start vibrating and wearing faster but it's not really something you'd experience unless you didn't clean them for 2-3 years.

Solved the mesh problem, made a new mesh from nylon mesh from a local hardware store and attached it with heat resistant adhesive to the front panel of the case.
