Hi. Recently I noticed that the fan of my 800W power supply doesn't spin (it spins just for a few seconds when the pc boots and does not spin anymore). I read somewhere that the fan only kicks in when the pc is on heavy load. I guess that a i7 2700K (overclocked at 4.3 ghz) 3 fans and a water cooler aren't enough to make the PSU hot? (Graphics card is a small 1050ti with no additional power required beside the one it gets from the PCI-e slot).
