Q6600 averages 73C at 21C ambient with OCCT, G0 stepping

[BehindEnemyLines]

NEW CPU:
Stock heatsink/fan, AS5 paste, 2.4GHz, 1.3250 VID, G0 stepping, no overclock

On first boot-up, I tested it with OCCT. It originally went above 75C such that OCCT stopped within ~3 min, since the limit was set at 75C.

I tried using it for about 2 hours normally (browsing web, music, etc...) and ran the OCCT again. It now levels around 73C for all four cores at 21C ambient temperature tested full-load for 1 hour. OCCT was set to test just the CPU (not RAM).

I tried playing Crysis, COD4, and other games for the last two hours without any problem.

Do these full-load temperatures seem reasonable?

The cores idle between 35C - 40C (corrected), not 40-45C as previously indicated.

OCCT, CoreTemp, and SpeedFan reported similar temperatures, but Gigabyte's own program EasyTune 5 is about 13C LOWER than these programs.


OLD CPU:
Pentium-D 805. It averaged about 40C idle, almost never above 55C full-load.

reseat your cooler. Mine idles under 30°C at 3.0GHz so something isn't right.

 

[BehindEnemyLines]

A slight correction: It idles between 35-40C. If I do just "normal" thing, then the cores are < 45C.

I double-checked the heatsink, and it seems all four pins are inserted correctly. This is observed from underneath the motherboard. The heatsink doesn't wiggle or otherwise move if pressure is applied. I suppose I could reseat it.

I am not too concerned of idle temperature, but it would seem the full-load temps are a bit high.

 

[Gillbot]

Your load temps are too high as well IMHO. Check your TIM and your cooler mount. Sometimes it appears as though the pins are properly inserted but they may not be.

My Q6600 on air at 3.1GHz topped out full load at around 60-64°C

yes, you need to reapply your thermal compound and reseat the hsf. I know that it's a royal pita but you are WAY too high, esp with that 21c ambient.

 

[BehindEnemyLines]

If it helps, the Q6600 has 1.3250 VID according to CoreTemp and RMClock. I think maybe it has the highest possible 1.3250V when running full-load???

 

[Gillbot]

mine is the same, check your TIM and cooler.

How did you apply the TIM? I use the traditional method of a thin layer on the spreader.

Should I follow this "line" method: http://www.arcticsilver.com/pd...s5_intel_quad_wcap.pdf

I followed that instructions too when applying AS5 on my Q6600 B3. I use to spread it all around the CPU's heatspreader until I came across that manual, when I got the AS5, it didn't come with one

Honestly I hardly see any difference, but maybe it's just me not being observant enough. But I trust that AS5 applying technique, it's their product after all

In my room where the ambient temp is 32oC / 90oF, CPU idles at around 51,52,48,49 oC. Running SETI@home, crunching on all 4 cores stresses it to 71,71,66,67 oC. Running Orthos or Prime95 on 4 cores stresses it even more to around 75,75,72,71 oC

Hence I don't dare overclock it higher than I have right now (333x9 1.325V Bios, 1.288 VCore-drooped), since I will have to raise the VCore to 1.4V Bios (1.35V drooped) if I want to run it at 3.2GHz.

I tried Orthos at 3.2GHz, phew CPU temp broke the 80oC barrier, not worth frying my CPU

But anyway, since I came across the instruction, I've been using the "line" technique for my quad.

I reseated the heatsink using the "line" method. It's a definite improvement, and the CPU never reached 70C given how it exceeded 75C before re-seating.

The new results are:
Idle: ~30-34C
Normal: ~35-40C (this is web browsing, listening to music, and using BeyondTV for television)
Full-load (OCCT): 65,65,67,67 for one hour
Ambient temp: ~21C

Is a modest 3.0 GHz possible, or is a better cooling solution needed?

If you want overclocIk I would get after market cooler. Mine vid 1.25 at 3.420 and i hit 63,63,60,60c on prime small ffts . Good cooler should easy make 3.200 maybe more.
Heres a link to temp guide , if interested i like this one. http://www.tomshardware.com/fo...core-temperature-guide

Oh forgot my temps at 23 c ambient

Better, but as taihuia13 suggested, get an aftermarket HS, Stock HS just plain suck!

that's much lower than my undervolted qx9650 @3ghz (idle voltage 1.072 in cpuz)
with a torrent download in the background, the idel temp is around 36-38c in coretemp 0.99 (room temp is 22c), prime95 or occt @50-51c.

lapped qx9650@3.0 undervolted
lapped ultra-120 extreme+ Noctua P12 1300rpm

you should make sure that both surfaces are flat and completely joined. Lapping may be neccessary for that but there is no better way to make a heat transfer than touching flat bare copper to flat bare copper. Use the smallest ammount of TIM possible, evenly spread, almost looks like a grayish/silver haze. Then mount firmly.

I used a Thermalright ultra 120 and lapped the e8400's IHS & the HSF. Excellent temps even at 4200mhz loaded.
