Sounds good, THANK YOU. I think I may have put about 1 whole grain of rice worth of as5 on when I was aiming for only 1/2 so that might have done it. Ill redo it tonight as its really easy to fix and see how that goes. +rep.

Damn I reseated the heatsink and it only dropped 1 degree. I was very careful this time too. I dont know what to do about it...I do notice that my load temps still dont go over 43-44c which is strange or maybe the idle sensor is off? Anyone got any recommendations?

Those load temps (if you're sure that it's 100%) are perfectly fine, so I wouldn't worry about your idle. I load at 50C, so using a 45nm, you're doing ok.

Ok, im going to run crysis a couple times and monitor the temps...Hopefully it will be ok...That makes me mad that I might not be able to hit 4.0 because of my temps.

Hell, bump it a bit and see what your load gets to...see how the 45nm saves you some heat. Get it to 3.5GHz, and if you're still under 50C (and you might be, just because it's a 45nm) push it some more. Don't use a game to stress test yourself, get Orthos or another app that will fully load your cores to 100%. In orthos, just select "Small FFTs - Stress CPU" and let it run for an hour or so to test not only your temps, but stability.

OK, I will do that. +rep for your help! Thanks!

Ok, I overclocked to 3.8ghz last night and it ran full load about 55-60c average with a very small peak to 63c. It didnt stay at 63 but for a few seconds then dropped back to around 57c. I let prime95 run on both cores for over an hour with no problems or crashes (though I know it needs to run longer to verify stability). Do these temperatures sound good to you guys? Or do you think im running a little too warm?


Also I ran a couple games and it really never went above 53-54c so I was happy to see that.

Wow, I installed my new 8400 last night and it is idling at 42-45 with peaks to 56. My old 6400 idled at 32 and never got above 45. I think I applied too much AS5.

Is half a grain of rice really all that you need? And what is better, to spread it out yourself or to just let the mating of the proc & HS do it?

Ive heard mixed opinions on the application of as5. Me personally I apply a half grain of rice worth of as5 and let the heatsink spread it out. Some have talked about using a card or razorblade and spreading it out before you set the heatsink but it sounds a little risky to me. Another thing you want to do is download realtemp if you dont have it already as realtemp will give you more accurate temps for 45nm procs. You may have also applied too much as5 as you mentioned already...how much DID you apply?

as5 takes a few weeks to settle in, mine was high at first but its fine now, im idling at those temps and im at 4ghz
