I have a i5-6700k and a masterliquid 240 cooler. Recently the temperatures while gaming have gone up to 80 degrees celsius, while on idle goes down to 30 degrees celsius, as well as a noise coming from either the block or around the fans when temperatures are high. Is this because my thermal paste applying skills are horrible, or because there might be something wrong with the pump? (Both CPU and Liquid cooler are fairly new)
