Im new to building pc's and 4 days ago all my parts arrived and i built the PC, but when i was installing the heatsink that came with thermal paste pre applied on the bottom, i put it on the wrong way (wrong way meaning the latch wasnt able to go down and lock it) so i took it off for a few seconds and then placed it the other way then it latched into place. im wondering though cus ive been using the pc for 2 days now and have been playing alot of games on it and i can hear one of the fans in my case sound like its working hard and im wondering if it is the cpu fan overheating because of air bubbles from the thermal paste. Should I take the heatsink off and apply some more thermal paste or am I fine.
