[SOLVED] CPU temps fluctuating

[jason99vmi]

Over the last couple weeks the CPU temps have started to fluctuate a bit. Idle temps which were usually around 38C, are now around 40-50C. Getting really high temps playing almost every game 70-100C. I know this is bad. In fact I was just downloading a large file from a webpage and temps hit 98C. Turning off game though will bring temps back down in the 40s.

I have taken the liquid cooler off twice now and replaced thermal paste. Cleaned all the dust out of the case. Opened the case to allow more cold air in.

I touched the hoses of the cooler and one is hot and the other cold. Cooler plate did feel warm to the touch under those higher temp loads.

So i can't tell if the cooler is dying or the CPU is starting to fail?

CPU: i7-4790k
cooler: Asetek

Sounds like your cooler is heading for the grave yard. How old is it?

About 5 years old. Already bought a new one so i'll swap out and see if that is the difference.

But when CPUs start to fail do they do this heat fluctuation as well?

that specific cpu is notorious for running hot
i would say it's your cooler, have you cleaned out the filter for gunk and dust buildup? it can do wonders

Dumb question. Filter? in the cooler radiator? I blew out the fans on either side of the radiator but no didn't take it apart.

If one tube is hot and the other cold that means there is no flow. You either have a clog, or your pump impeller disintegrated and is not pushing the liquid.

Oops i meant the radiator yes, but given the fact that you have already cleaned it, i'd say just go with the new cooler

Ahhhhh I read somewhere they are supposed to be like that. But i guess there is bad information anywhere.

Thanks! I'll just install the new one.
