Diffrent Core Temps?

[monoboogie]

Im running a Q6600 overclocked to 3.6ghz at 1.5volts

Im cooling it using a Zalaman Reserator w/ the fan with an extra pump.

My idle temps hover around 33 C depending on the room temp.

When I stress the cpu via Orthos, core 1&2 will hover around 47 C
While core 3&4 will stay at around 38-40 C

This seems really weird to me, so I tried resitting my cpu block (apogee gt), it didn't make a difference. It seems like my artic silver job was good enough.

Is this a normal occurance for the Quad Cores? Or do I have to check my setup again?

thanks for the inputs! =)

well, having different temps on the cores is rather normal.
It would definitively help if you lap both your CPU heatspreader and your water block

Run Prime95 with small ftts; this benchmark would be a better indicator. If you still see this large difference in temps I would re-seat and reapply TIM.

If you're not running a 4 core stress test then your temperatures will be drastically different. Make sure you're not running a dual-core stress test (or make sure you're running two instances of it).
