I've just succeeded in overclocking my core i7-920 to 3.8 ghz using my brand new Noctua nh-d14 cooler
There are no issues reported when testing the stability of the system using prime95.
The only thing that bothers me are the cpu temps. I don't know if they are getting too high so please help me out here
This is what CPUID Hardware Monitor reported after prime95 test: (Idle/Load 100%)
Core #0: 45/79
Core #1: 42/77
They seem fine to me...some people will say that it is a little high but i disagree, i have an i7 at 4ghz on air so I am speaking from experience....with the stock cooler and stock settings these i7s hit 80c under load easily they are meant to be hot......the only thing is the hotter you go the shorter the life span of the chip but by the time that comes it will be obsolete and you would have replaced it by then....All in all your good and congrats on the OC its always nice when it works out...what thermal paste did you use? if you used AS5 ur temps will drop like 2c after a while so your are def good in my book....one thing to think about is come summer time are you gonna be running the AC alot? if not you may want to consider dropping the oc when it gets hot or maybe jus not game as much
I'm using the thermal paste that followed with the cooler (NT-H1)
I'd guess that I just have to see how things work out for the cpu when it gets hotter. As you say, I can always underclock it if I run into temperature related issues.
Thanks for the reply. I feel a lot more save now
Id say they are too high imo you should never go near or above 70c, will it break? probably not.
Okay, I've been testing the cpu all day now and there is only good news to report
After playing Flight Simulator X for about two hours, I was wondering how my cpu temps were doing. And guess what. The core temperatures barely reach 60 degrees (one core had a max of 61 degrees). This is indeed great news because I don't play a more cpu demanding game
My understanding is D0 step chips will overclock higher and run cooler.
I have a D0 i7-930 @ 4.0 GHz with a not quite top notch (I paid $30 for it) heatsink/cooler and it runs Prime95 with max temps of 77 C. I've played Civ, Dragon Age, Bad Company 2, Star Trek Online and not once did the temp break 51 C.
Would I like to have cooler temps running Prime95? Yes, but I won't run out and spend an extra $50+ just to get there, especially when current games don't stress it hard enough. When I start playing games that start sending the temps above 60 while playing games, then I'll drop the cash.
I think you're OK, but have you tried stepping down on your voltages at all? Maybe you could lower them slightly, still be stable, and reach a lower temperature if you are uncomfortable. And as others have said you will notice a 2-3 C drop after a week or two if you had a good application of the paste.
Well for comparison, consider that my son's 920 is running in the hi 50's (55-58) at 3.78 GHz (HT and all other BIOS functions enabled). I'd give part of the credit to the Prolimatech Megahalems which outperforms the Noctua DH-14 by about 5C on the 9xx platform.

However, have you optimized the voltage ? This link was recently revised from the 920/930 to the 950/960 but all the info still works. My son's is running at 1.1125 volts under that profile .... the 4.0 and 4.2 GHz profiles run w/ higher voltages and temps.
