Hi! :) 

I put together a setup consisting of:

case: temjin tj08-e with additional 120mm gentle typhoon fan
MB: asrock Z68 PRO3-M
cpu : i5-2500k
cpu heatsink: coolermaster 612

I flipped the fan, so instead of blowing, it sucks air through heatsink fins
otherwise the thing wouldnt have fitted into the case, the airflow throug
the case is uniform from front to back, no fans are working against each other.

I reapplied thermal paste twice, once with spreading ultrathin layers
to both CPU and heatsink base, the other time I used the one small drop to the center method, both times the results were alike. The thermal paste is OCZ freeze.

I overclocked the CPU to 4GHz and used CPU voltage -0.025 in offset mode.
When I run OCCT or intel burn, the core voltages get as high as 85C which
for me is unbelievable. Also there is up to 13 degree difference between the
cores. This heatsink is massive, I was expecting 10-20 deg lower numbers.
Can the problem be in a badly applied thermal paste, faulty heatsink or
maybe bad thermal connection between the die and the metal cover of the CPU.

With best regads,
Mark

Check your fan RPM's, it could just be going to slowly when it needs to be going faster. You switch that up in BIOS.

Hi,

the bios is configured like this:
sorry for the large images, resize function didn't seem to function in this forum.





I don't have much knowledge about configuring bios parameters, so if something
seems odd or utterly wrong, then please don't keep it to yourselves :) 

The voltages and temperatures during idle and load are here:

With the main fan at 1200rpm



With the main fan at 700rpm



Both screenshots are taken after 60 seconds of loading.

With best regards,
