So just recently bought some parts used over craigslist, had a friend help me build the pc up, heres the parts first off. Case is a Diypc Cuboid case, Motherboard is a msi a68hi, cpu is a AMD x4 860K, gpu is a gigabyte gtx760, power supply is a corsair cx600m with a 1Tb hdd. I recently upgraded the cpu cooler to a coolermaster evo 212 and had no luck with it at all, installing it seemed to go ok but it can turn about 5 degreese if you try to move the cooler, dosent rock back and fourth though but I read on fourms it seems to he notmal for some, i tightned every screw as much as possible and everything, I added a pea size amount of the thermal paste although seemed to be more than what I needed so i wiped off the tiny bit that gooped over the side, idle temps are about 60c and under load its about 75-79c and sometimes maybe 80c, not sure what the issue is. Thought about maybe dumping the cpu cooler and going for maybe a corsair watercooling loop but just not sure whats wrong even though i dont eant to spend the extra money for a watercooler nor do I have the cash at the moment. If anyone has any input or help, it's greatly appricciated. Keep in mind this is my first pc I built ever.
