So I'm new to this thing and I took my brackets off and put my stock cooler on my cpu and screwed it down without putting the 2 brackets back in it seems snug but am I suppose 2 have the brackets in between the cooler and you or something? I might add I took the cooler off for a couple mins then put it back on without reapplying new thermal paste. It was never turned on so I think the paste should be ok ...right? Help lol
