I am running on very low electricity costs inside a DC where temps are from aircon. Any reason why I shouldn't let the fans run @ 100%? I mean nice for the D3's if the chips is sitting at 69-71 degrees Celsius. Lastly... any reason why I shouldn't push them a little harder if I can keep the temps below 79? Thanks!
They are just cheap fans. There is no reason not to have them at 100% if you can stand the noise. They don't take up that much electricity anyway, even in high cost areas.
