Hey guys, I’m having CPU cooling problems. I have an intel i7 6700k cooled by an EK-XLC Predator 280 AIO cooler. It has worked flawlessly for the last 3 years however just now my CPU has started to overheat it gets up to about 89-90+ degree range just in desktop. Is there something I can do maintenance wise to the cooler? As I have never touched it since installed or should I just buy a new cooler?
