Just finished building my second gaming pc and for this build i used the Cooler Master 212 Evo http://www.coolermaster.com/cooling/cpu-air-cooler/hyper-212-evo/ (my case has the room for this fan so space is not a concern) but im worried that the cpu heatsink will fall off as the computer stands up straight so the cooler is sideways (the way its supposed to be). The screws are not all the way in as it seems although i defantly felt force when screwing them in the star pattern after about 1-2mins so i stopped there, gave the cooler a wiggle both sides and showed no sign of movement (very little so its not to tight, although this movement wasent moving across the cpu it was more of a wiggle and not completley stiff heatsink). Im not sure if theres anything i need to be worried about or if its just my cautious self getting to me again, if re-applying the heatsink is a must that is no probblem for i have plenty of artic silver 5 compound and thermal compound remover(s). Thanks for all the support!
