I just got done with an i7 920 + EVGA E758 SLI build. We are using the Arctic Cooling Freezer Extreme heatsink.

Idle temps using Real Temp are 55C-60C. Load is upper 90's!!!

We did make one small mistake when building. The heatsink slipped when we were mounting it and it put a very very very small scratch on the cpu. When I say small, i mean small. You cant feel it by touching it and figured it would be filled in by the thermal paste.

We set the heatsink with a small amount of arctic silver 5 in the center...about a pea sized ball in the center.

Any suggestions on what is the most likely cause for the high temps. I figure it's either the way the heatsink is set, the quality of the heatsink itself, a cpu manufacturer defect, or possibly the scratch on the cpu.

Also, BIOS is updated and all voltages are set to stock.

Any help would be appreciated!

Well that is high temps for the i7. First thing i would do is redo the heat sink.

If that doesn't work, you could try under-volting the cpu. That will help reduce temps without losing performance.

If that doesn't work then all i can say is send it back to intel (or to the store where you got it from) and get a new one.

here a temp guide for the core i7 that made by CompuTronix

This may help you out.

Thanks, I am going to reset the heatsink this afternoon

I think pea sized is too much thermal compound.

I was having 60C temperatures at idle with my X2 4800+.

I reseated the heatsink, and I applied a single drop of AS5 (much less than a pea), now my idle temperatures are around 38-40C.

I read once that too much thermal compound is as bad as too little.

Be sure to clean the heatsink and the CPU thoroughly to remove the old thermal compound.

Good Luck

System Monitoring

There are several options for processor core temp and system temp monitoring. For a discussion of what is different between the apps I am about to list, see this thread. PLEASE READ THAT THREAD BEFORE ASKING QUESTIONS ABOUT WHY SOME OF THESE READ DIFFERENT TEMPS!

These first two will give you just the core temperatures (not system temps, voltages, etc.):

Core Temp (freeware)
Real Temp (freeware)

The next three will give you core temps plus many other temps, voltages, fan RPMs, etc.:

HWMonitor (freeware)
Speedfan (freeware)
Everest Ultimate (shareware $$$)

Who's this 'we' you refer to in your post?

Anyway first of all the Arctic Cooling Freezer Extreme is a bad choice or HSF, second of all use the line method for applying the compound them place your HSF on top but don't secure it just yet. Move your cooler around gently as if your massaging the thermal compound into the CPU then lift up the HSF and see how much surface area has been covered by the compound. Once your happy clip your cooler back into place and make sue the fan is attached to the motherboard (it might be an idea to keep the side panel off when you boot up to make sure the fan is spinning).

The 'we' refers to me and Justin. Hope that helps.

I think our decision is to replace the Freezer 7 Extreme. We found a good deal on the Corsair H50 water cooler and I have had good experience with those. It's not that I am big on water, but the size of the waterblock and the way the radiator mounts makes this a much better-fitting cooling solution for his case. That freezer extreme was a little close to the PSU and probably taking in as much heat as it was dissipating.

We did use the i7-specific "line method" for the Arctic Silver paste. We tried remounting a couple of times and actually got much cooler temps. The original mount was bad. Even though the temps came down, they are still outside of the norm (over 70 at stock).

My guess is that the heatsink swap will help a lot.

The thermal paste should be applied thinner than a human hair; the thinner the better. Also make sure the heatsink is properly fastened so that each section of the CPU heatspreader has the same pressure from the heatsink.
