One Core is 30+ degrees Celsius hotter than the rest

I have an i7 7600 that i installed recently. I have no programs except my browser opened as well. Is it normal for one core to be 30+ hotter than the rest?

No, that's not normal. I would say it's a bad sensor but you should download and run the Intel CPU diagnostic tool to see what it gives you. What does "Core 7" read out as?

it stops at 6, 7600 is a 4 core processor though so im not sure what those temperatures represent

Jwpanz :

You may also want to reapply the thermal grease just in case it is not spread on the cpu correctly.

As a side note. My last motherboard, using the same cpu i have now, always read 1 core 10c or so higher then the rest. It turned out that it was constantly getting fed more voltage. With my current mb this no longer happens.

I ran the intel processor diagnostic tool and it passed all testing. Do those temperatures represent something else possibly?

Have you had any crashing or any abnormal behavior? if not likely just a bad censor, ive seen it happen before, simply dont worry about it. however it couldnt hurt to explore the matter further ither.

If the diagnostic too came back fine then you should be good. My guess remains the same: It's a bad sensor. You could try running a stress test like AIDA64 and monitor the temps in HWMonitor.

Also, you could try updating the BIOS. It may or may not correct the issue but it's worth it to try.

I'm looking at your HWMonitor photo and it looks strange. Usually, the CPU temperatures will display like this:
Core #0
Core #2
Core #4
...
And so on. Do you see that under your CPU menu for temperatures?

I've had no crashes or abnormal behaviour. The program i was using was not HWMonitor, i deleted it though and can't remember exactly what it was. I downloaded hwmonitor and it is showing how you mentioned, with all tempreatures in the mid 20 degrees celcius. So it probably is something I shouldn't worry about?

Jwpanz · May 19, 2017

It must have been that specific program showing the weird temperatures. HWMonitor is a reliable program and many people trust it to work. I would not worry about it since both the diagnostic tool and HWMonitor are showing good results.
