CPU temps high all around, concerned...

i7-920 OC'd 3150MHZ (21x150)
12GB corsair domm 2000 @ 1800MHZ 9-9-9-24
ATI 5850 OC'd 825/1100

ZALMAN CNPS9500 all copper

So, getting concerned with my CPU temps. I was consistently idling at 65*C, full load was scratching 80-90*C..... yes very high. . . i know. Since I've been running the rig for almost 2 years I figured it was time to reseat the heatsink. Snagged one of those fancy AS5 cleaning kits and new tube of AS5. Cleaned, tinted, applied, slapped on cooler.

Temp only dropped 5-7*C, now idling 57-60*C. Hmph. Airflow in case is pretty good. Have 2 120mm intakes in front, 2x80mm exhausts in top and one directly behind CPU cooler.

Other idling temps in case are HD's 30*C, GPU 40*C, Mobo sensors range between 40-45*C. Room temp is probably ~23*C. CPU voltage is @ 1.25v in bios.....but for some reason cpu-z shows 1.216.

Kind of clueless. I'm guessing it could be my heatsink. It's recycled from my previous core2duo build, bought the 1366 mount kit upon this build. It should still be much cooler than this considering. I just can't believe I'm running this hot, it should still be much better than a stock cooler......

I'll have to reset back to stock CPU clocks just to see how it effects the temp but I did it just the other day and I want to say it only lowered idle temps by about 5-10.

Any insight on my problem?

I take it that this system is air cooled.

Usually in 2 years, the heatsink loads up with enough dust bunnies to increase the heat to a good level. With that said, the fan on the heatsink will work harder until the dust gets into the rotating parts to drive the fan. Also, heatsink fans are usually the sleeve types and not known for the long life durability. Your option other than reseating the heatsink is to find a fan replacement for the heatsink. hopefully, that fan will be a ball bearing type.

I'm guessing it could be my heatsink.

Want to know what I'm guessing? I'm guessing... what kind of heatsink you are using. So far I'm drawing a blank.

I'm currently having the same problem with a G0 Q6600 and an old Cooler Master Hyper TX2 in a Cooler Master Centurion 5. Starting from yesterday, my computer kept restarting and I discovered that the CPU was reaching over 85 degrees! I cleaned and re-seated the heatsink with AS5 (also tinting the heatsink base and the IHS) and although the computer is running a lot cooler, I'm still idling at 46-50 degrees and my load temperatures reach 70+ degrees. This is at stock settings, with a core voltage of 1.184V. Room temperature is about 25 degrees.

I only have an 80mm front-intake fan and a 120mm rear-output fan and my 5870 idles at 48 degrees (22% fan speed), so maybe the airflow in my case is poor, but I wouldn't think that it would be enough to raise the temperatures by this much. I'm wondering if the pins on the LGA 775 mount aren't securing the base sufficiently tightly, despite my pushing them in hard enough to flex the motherboard and make my fingers numb. In any case, now I have cuts all over my hands and a Q6600/TX2 setup that can't even reach 3.0GHz without overheating under load.

None of this information is really helpful, sorry. I hope you can figure out what's happening soon.

To the OP, if you have cleaned out the dust and still have high temp issues, some more information would be in order. What were your temps when you first built/overclocked the system? Where are you seeing these temps? Are they the same for all cores? Do the temps in Windows match the temps in the BIOS? Drop all speed and voltage to stock and see if the temps get better.

good luck,

Laminator, do you have EIST enabled?
