30 degrees diffrence between cores !

Tellur · 31 Jul 2018 at 18:35

Hey, I was benchmarking my i7 4790k with Aida software and I noticed that's my CPU temp on core 1 is 30 degree higher than on my core 4! I dont think this is normal. Thermal paste is new. Mobo: asrock z97 killer fatality, cooler dark rock 3. https://ibb.co/dcCkQe

Is it delidded ? if not, id get a kit tomorrow and try and sort it out.

@jaming280672 No, the only thing I did to it is I put my thermal paste and covered it with my cooler. No delidding. More informations for the post: I reseted my bios settings with no results, clock speeds are same for each core.

I'd check the cooler to make sure it's seated correctly.

This, looks like one end isn't touching well. Take off the cooler and check the shape of the thermal paste on the cooler

@acemastr @Robzere31 I checked it already thermal paste looks okay it has no gaps and its amount is okay too. When I took it off shape on the cooler seemed squarish so no problem with that too. I even tried to push my cooler harder with my hand while benchmarking and it had no impact on that core at all. I`m so confused, maybe its the built in processor thermal paste which is the source of this problem. If so ... I have no experience in delliding so I do not think that I can solve that problem than ;s

There are kits for delidding, or services. If you're handy you can do it yourself, I did.

Lots of information online - do your research before jumping in. Looks well worthwhile for your chip though

My 4790k also goes to very high temps , at idle it sits at around 36c but load up a game and it goes straight up to 80c , and in-game can go up to 90c and over
