Hey Guys!
I really need some help with my Corsair H80
Stock (Pull)Fan/radiator.
I noticed just the other day that it stops and resumes its spin every 30 seconds or so while my system is idling and even when I ran a stress test. 
I tried:
-Exchanging fan connections in the pump
-Holding the speed button when booting up so that the light in the pump blinks. Either I did it wrong or It was of no use.
Is that a normal thing or should I be doing something about it?
Btw, my fans/radiator are configured so that they suck air from inside the case and blow it outside(exhaust). They're located at the back of my case.
Any help would be much appreciated!
