[SOLVED] I7 4790k overheating

luka.marolt · Nov 16, 2018

I just installed new i7 4790k in my pc. The cpu gets to 90C degrees after just few minutes after turning on, idle.

The fan is spinning full. Stock intel fan, I think it dosnt have thermal paste applied and I didnt apply it either.

I looked at voltage in Intel XTU and everytnih looks fine

I installed new cpu cooller to my old cpu and it runs 50+degreesC when idle. Could be the lack of thermal paste to couse severe overheating?

You always need Thermal Paste. Why did you even try to run the PC without it?

luka.marolt · Nov 16, 2018

I read that it s not really necessary. Ill get it and apply it today. But can it really be just the paste as the cpu runs really hot few minutes after boot?

If each surface was completely flat you could get away with no thermal paste but that's not the case mostly. Thermal paste is used to fill the imperfections and that tiny gap i mean TINY can make a huge difference in temps as the heat transfer needs to happen quickly.

Just a pea drop in the middle of cpu, put heatsink on carefully square to the braces. Once in that position, tighten heatsink in an X fashion like tyre nuts. Once finger tight do a half more turn with a screw driver. Or if no room for hands just easily turn screw driver until you feel it stop with no pressure from you, then do a half turn more with pressure.

Will do, I hope it is just the paste!

You never ever mount a CPU cooler without TIM.

^ Not drastically as described but good enough advice.

I Installed the paste, set the power option to save. When idle it runs fine at40C.
When rendering it still gets over 90C at 100% working.
I think I should edit settings in XTU But it crashes and reboots and changes are not saved? I reinstall the xpu and it the same

Hows your case air flow, intakes and exhaust?

What cpu cooler do you have?

Also what ambient tenp in the room?

luka.marolt · Nov 17, 2018

Air flow is ok, previous cpu worked fine. Cooler is stock, ambient temp around 25C

boju · Nov 17, 2018

What previous cpu? Didn't 4790k come with a cooler?

Looks like the cooler isn't doing a good job. Get a Cooler Master Hyper 212

luka.marolt · Nov 18, 2018

Yes it came with stock cooler. My previous cpu i54430 worked good with its stock cooler so the air flow in case is okay.

I ordered cryorig h5 ultimate

boju · Nov 18, 2018

It sounded like from your other reply you were using another cooler from a lesser cpu to cool the 4970k.

Good luck with the cryorig, it's a decent hsf and should solve your temp problems.

Remember to reapply thermal paste and also just a pea drop in the middle.
