Why does my PC keep overheating? How can I fix it?

Which way is the airflow through the CPU cooler radiator? The fans should be oriented to take the CPU heat straight out of the case. Some makers instructions say they should blow inward for some reason - that's daft, it does away with all the advantage of a liquid cooler, which is to keep the CPU heat away from the rest of the parts... Overall airflow should be in through the front of the case and out through the top/back. Other than that, make sure the radiator is clean; they do tend to clog up with dust quite easily and need brushing out every few weeks.. One other thought - what heatsink compound did you use and how much? The proper types are like a soft grease, not a thick paste. The idea is that it spreads and only fills the microscopic imperfections in the CPU and heatsink surfaces, it should not hold them apart. Too much reduces heat transfer rather than aiding it. It also needs to be put on so there are no air pockets - a single small blob in the middle of the CPU, that spreads under pressure from the cooler is one way of ensuring no trapped air. Many of the expensive metal-based "CPU thermal grease" products do not work as well as basic bulk commercial white zinc oxide thermal grease and to give you an idea of the best consistency, one magazine doing a comparative test included other oils and greases - and mayonnaise worked better than 90% of the "special PC CPU" products, though I'd not expect it to last more than a day or so...

A few months ago the pump died on my h115i Extreme, which resulted in higher than normal temps. The dead giveaway to a dead pump is one hose being hot and the other hose being cool. The PC, which was also using an 8700k at stock with a Gigabyte Aorus Gaming 7 board would throttle when the CPU was being used by a moderately taxing program or if the GPU was in use. Corsair was nice enough to exchange my dead h115i Extreme with the newer h115i Pro. Dead pumps are a widespread complaint with the x62, so it wouldn't shock me if you have a dead AIO cooler on your hands.

Could simply be a matter of using compressed air to clean out the vents/fans
