cpu cooling efficient ?

[leclod]

Ok, this just occured to me.

I was running the 3DMark stresstest on my system.

I display cpu and gpu data via Afterburner.

My cpu temperature is quite jumping around, often making 10°C jumps while my gpu temps slowly rise.

Could there be something wrong, like a bad cpu/cooler contact or is this to be expected, being a bigger threshhold between die and casing than by the gpu and also different load ?

If you run a pure cpu stress test then you will probably see the chip temps go up and then hit their full usage temp and stay within that range...I use coretemp and cpuz bench to give a quick test

I'd say that it's a combination of a more variable load and the IHS between the CPU and the cooler being less efficient than the direct-die approach used on GPUs.

Yeah, good point, the cpuz bench gives slowly rising temps. Thanks

Cpu threads get used and not used all he time, 10*c CPU temp delta variance while actively using the CPU a little bit isnt a big deal.

 

Unless its close to like 85- 100*c with low loads but you didn't say it was...
