overclocked and temp on individual cores soars to 68c

here are my specs
maximus formula
q6600 go stepping
8gb gskill pc8000evga gts512
zerotherm nirvana
vista64


when left at stock my cpu temp is about 27-30c, mb temp is say 33c. but each core reads 30-34c. under load cpu temp goes to 40, mb temp 43 and the cores go to 43-46 still well within range. This is with asus probe and everest<probe doesnt monitor cores just cpu temp> this is all good so far

when I overclock it to 3.0ghz by cpu level up. Im just getting my feet wet here and wanted to do a test run this way.
I get cpu temp 43, mb temp 46. this in both everest and probe. but the cores go nuts in everest. when stressing it with prime95 each core will climb to 65-68 in under an hour. I shut it down because I didnt want any problems. Is this something to worry about? its stable and it never crashed, though its only an hour. but the heat disturbed me

^ agreed

Your problem is that Level Up is overvolting the cpu which creates a lot of heat. That will cause the problem. Those G0's are good till about 70C so you're just in the limits

Hawkspur.....i need pics

Coretemp and Speedfan are pretty much the standard.

Silverion, it's still not done yet. I had to RMA the motherboard and it doesn't get here until Wednesday. Stupid water and its electrical conductive properties...

I could be wrong on the vcore. Im at work and doing it from memory.

Im using as5, one thin line across the cpu. the cooler is facing the back of the case and blowing right into an exhaust fan

Im using the zerotherm nirvana. ive been thinking of changing it. If I tighten all fours screws I get a cpu init error. I have the top two tightened down all the way and the bottom two backed off a bit. They are tension screws so Im assuming they dont need to be tightened all the way to get a good connection. Im also basing that on my temps being fine at stock speeds. or am I wrong in this assumption.

to be honest I had all four screws backed off a bit to avoid a cpu init error when i was building it a few weeks ago. But I didnt like it. looked like it was hanging down a bit. so i tightened the two top scews all the way down and I was still able to post and the temps looked ok. so i called it a day.

I will tighten them up sunday or monday when i get a little time. Maybe because the top two are locked down it will let me tighten the bottom two without a cpu init error. then I will know its not how its seated. the zerotherm has tension screws, so Im assuming its not necessary to go all the way down. otherwise why use a spring in the first place. but what do I know...Im a noob at this stuff

thx for the help
