CPU 87 Degrees at BIOS, 60 Degrees at Desktop

[lynext]

Hello, I'm facing a really bad overheating issue. First I thought it had something to do with thermal paste then I removed the heatsink and I saw that the thermal paste was gone. Then I bought one and applied to the cpu and the heatsink.

But, it did not help even a bit. While in a main menu of a game (Tom Clancy's Rainbow Six Siege) i see that my CPU is 95-98 degrees. I used core-temp, aida64 and speedfan but the heat value is all the same. But when I touch the heatsink, it is even below room temperature ! And the cpu stock fan is crazy loud.

I think my CPU heat sensor is broken because heatsink is cold and thermal paste is applied. And that makes the cpu fan loud because it thinks cpu is hot. Any help ?

CPU : i7 2600 non k
GPU : Asus GTX760

Note : My computer was pre-built but the GPU was so bad. I changed it with a GTX760 and the pre-built power supply was not enough so I had to change it with a bigger one too. Could this be the issue ?

I suspect that your heatsink is not connected tightly enough to the CPU/motherboard. Poor contact means poor heat dissipation.

I would recommend changing the OEM (original) heatsink with a non-pushpin heatsink that will mount more securely and produce much better results.

What is the make/model of your pre-built system?

It's Asus CM6850, I tried pushing the heatsink to the cpu with my hand, no change. I'll try a non-pushpin heatsink.

The strange part is, while playing a game it shows 95-98 degrees, but I keep playing with full performance for hours, no lag or crash.

You could have a defective heat sensor as well.
