i7-4790 Hot temps on low loads on H81M motherboard.

mahmoudomar123 · Nov 12, 2017

I have an i7-4790 and I noticed something really weird while playing, the temperature hovers around 70C-95C while on 20-45% load, I have a stock cooler and I just applied new thermal paste 2 days ago and the cooler is mounted correctly.
My motherboard is Gigabyte GA-H81M-S2PT, BIOS Version F5. and Windows 10 Enterprise 64 bit.

The stock Intel cooler is junk and the Devils Canyon i7's run warm, get something like the Cryorig H7 and just make sure it will fit into your case.

I've used the stock cooler for around a year and a half and it was working perfectly.
I've only had this issue with this motherboard, I had a Z97 but it died and temperatures were good, Also, when I got this motherboard I didn't install a clean copy of windows.
I had another H81M and it had the same issue. could it be the windows or something in the bios settings?

Have you tried monitoring temps with other utilities to see if the temps you already have can be confirmed?

You can run portable version of HWiNFO (doesn't requite installation) and see system temps:

I tried MSI Afterburner, HWMonitor, Speccy. all read similar results. but I'll try this one too..

If three utilities show the same results it's probably right. Won't harm to try this one too but I don't think it'd show otherwise.

What voltage is the CPU being run at when you get these high temps?

http://prntscr.com/ha2atm this is while I was playing CSGO, cpu load was around 30%-50%

I think voltages are OK. All cores have maximum usage around 80% at some time but only core 0 has apparently reached that temperature.

Maybe the heat sink is not sitting properly firm and flat on the IHS or maybe a problem with TIM (thermal paste) little or too much paste can disrupt conductivity and lead to over-heating.

Also maybe air bubble trapped in the paste on that one core.

Reapplying and re-seating the heat sink and cooler might help.

Many 4790Ks have had heat issue, then tend to run hot and a stock cooler maybe not up to the job.

i've got a 4790 on another rig, and it ran fine with the stock cooler for awhile on a Z97M-Plus Asus mobo - then temps went crazy. Turned out one of the white push pins kept coming loose. I'd check your pins are all still firmly in place
