Hello everyone, I've bought a new computer and I have a little concern. First of all, everything works great but I never saw the rear fan spinning... which seems wrong.

SPECS:
corsair 300r case
cooler master hyper 212 evo cpu cooler
intel i5 4670k
gigabyte z87x-d3h
corsair vengeance 8GB
evga gtx 780 SC ACX

I got the latest BIOS version of my MB (f8)

all my drivers are up to date.

I've been playing METRO LAST LIGHT on max settings and the GPU didn't go above 70 degrees. Finally, when I go in the BIOS it says that fan 1 and 2 are at 0RPM and the third one seems to be spinnin ahah...

Well can anybody help me figuring this out ? Is it simply that the rear fan don't need to spin because the computer is not too hot. Remember... I've never saw the fan spinning since I got it but the computer seems to be working fine.

Thank you:pt1cable:

Is the rear fan plugged into the motherboard or into a molex connector from the power supply? Normally fans spin at all times unless they are not connected to anything (unplugged). Exhaust fans will lower your case temperature more than intake fans will.
