[SOLVED] My i7-7700 is 100 Celsius at Idle ?

[EJ81HG]

I recently bought a pc with a gigabyte motherboard and an Intel I7 7700 and I noticed the CPU temps are way too exaggerated when I downloaded HW Monitor, showing idle temps between 65 Celsius and all the way up to 100.
I even checked in the BIOS and it tells me the same thing. Speedfan however shows lower values at 80 Max under load but the whole pc feels very cool and I tried using an infrared thermometer to point it at the heat sink and the highest temperature I was able to get was 35 Celsius under load. I’m not sure what the problem is.

And once again it happened.

Somebody has a problem and does not give any detailled information about used hardware.

Is it really so difficult to add a hardware-description after or before explanation of the problem ?

It is so annoying to ask again and again for used hardware.

When a CPU is hot and the heatsink is cool, that means the heatsink is not making proper contact with the CPU. The heat within the CPU is not being transferred away into the heatsink.

You need to remove the heatsink on the CPU, replace the thermal paste and install it properly. The Intel OEM heatsinks use 4 push pins. It is common for people to only get 3 of the 4 push pins fully inserted. I had one Gigabyte board where the amount of force necessary to get the heatsink fully seated was insane.

If you have a heatsink like this, push the push pins in two at a time diagonally on the heatsink. Do not push the push pins in one at a time or you probably won't get the fourth one to seat. You might have to pull the motherboard out of the case and look at the back side to make sure that all four push pins are fully seated.

As an aside I think it's pretty darned cool that you have an infrared thermometer available to you. Super cool little tool.

I tend to agree with @uWebb429 on his assessment as it's the lowest hanging branch and most likely culprit.

In the meantime you get to play with the thermometer to see what your VRM and backplate...and exhaust...../driftsofftomemoriesofGamersNexus

The problem was exactly this, I opened it up and moved the heat sink a bit and it had way too much play in it, I was able to get one push pin to go in further and the temps have already seen an improvement, at idle I’m getting around 30 Celsius on all cores and the max recorded by HWMonitor is 73 Celsius, nowhere near that 100 Celsius mark which had me worried. I’m still gonna remove it and replace the thermal paste but I guess this will do while I order a decent thermal paste.
Thanks for the quick and helpful replies.
