| Is 80C too high for 920 D0?
I have 920 D0 OC to 4.2 Ghz at 1.35 Volts running water.
With Prime95 blend I get 78C with 27C ambient
and with
Prime95 small FFT (all fits in cache so just CPU tested) I get about 81C with ~27C ambient.
All after 30 min of Primeing.
Are those temps too high for that chip and setup or is it standard? |

Almost sounds like you are using a stock heatsink for that overclock |

High temps have more to do with the OC potential than anything else. If you ask Intel, they will say it is well within parameters.
You should be able to get it lower. If you are stable, first thing I would do is back down the CPU volts if you upped it at all. Lower it until you are unstable, then back up a tick.
Then, you can see where you are. If those are stock temps volts wise, you can easily do better. If just leave it and are stable, there isn't much of a downside. |

Definitely too high if you are on water....
I have a Q9650, am on air with a Prolimatech Megahalems CPU Cooler @ 4.275 GHz with 1.408v & the highest I got priming was 75 after 11 hours...

Gone are the days when you can keep your CPU down at 40C, these core i7's just burn too much power especially when OCing.
I think I saw somewhere that they start the throttle themselves back at around 90C. I think 70-75C is a reasonable target. |

Remember,
When you start OC'ing your system, it's not just the CPU that you need to worry about. You really need to think about the NB / SB and other components on your motherboard.
All to often I get calls from colleagues / friends / family who decided it would be "Cool" to OC their rig so it runs faster. Then after some period of time, things fail on the MB (most frequently either the NB or the SB and I/O doesn't work so well any more.
So do yourself a favor and make sure your motherboard components are in temperature and voltage specification or your OC'ing may severely reduce the length of time your system functions.

that is just about right for your OC. you could lower it down by disabling HT or buying a better case with lots of air flow.
my 920 D0 OC to 3.9 @65C running on AIR
It has been crunching for WCG since march without hiccups. |

Within Intel's spec, I believe it is.
Would I let it run that high? No. What is your water setup like, that seems way too high for a water setup.

| said by The WeaseL  :Within Intel's spec, I believe it is. Would I let it run that high? No. What is your water setup like, that seems way too high for a water setup. From what i've read the 920 D0 chips run very hot when voltage is upped beyond 1.3 but still indeed it's quite hot.
However with 22C Ambient it only runs up to 75C.
The setup is:
Swiftech Apogee GT CPU Water-Block (it is an 775 block with an extra 1366 adaptor mount).
Danger Den DD5 Water pump (the 2005 version not the newest variac one).
1/2" Tydon tubing
Black Ice Tri 120" Fan radiator
6 Skythe Ultra Kaze 120"(133 cfm) Fans set on push/pull configuration
Radiator is outside of case and the pump is supported to the mid case height in order to minimize the gravity water head pressure reduction. |

Minnesota | Is the air coming from the radiator warm?
I am not familiar 920 running temps but that just seems warm.

The damn PC can heatup my room in 2 hours from 22C Ambient to nearly 28. 
But I am still wondering if the heatsink is not seated properly. However I do not want to fight it again trying to remove it and put it back on, it's a pain in the arse the way it's configured now. Additionally if I were to remove it I would have to leak test the setup again due to any torque that might have been applied to the tube couplings during the procedure. I lost one Motherboard once by failing to do that.
Hence I was hunting for a temp norm for that chip at those specs on water.
P.S.
The Wattage usage of the CPU is 147 Watts. |

| Well maybe she just runs hot then. If the air coming off the radiator is warm and its just the CPU, not sure what else you could do besides adding more to the loop.

With a CO stepping 920 running at 3.7 GHz using a 1.35 vcore with a Thermalright Ultra-120 eXtreme with AS-5, my idle temps are around 30 (70F ambient) and load 70-70c during P95 blended.
With a DO and watercooling, you'd think yours would be cooler. |

I'd say it's a little warm but could withstand more. IMO I'd consider checking the heatsink. I've seen that chip on air and was around the same temp as yours, well it wasn't quite 4.2GHz, recalling 3.9ish.
