My current temps with Coretemp are 45 - 50 C idle, 50 - 55 C with load. Im running this on a Gigabyte P35 DS3R, which ive heard sets the voltage a little higher than stock. CPU-Z says its running at 1.264 - 1.280. This is in an Antec P180, which has 3 120mm fans. Using Nocuta UH-12F heatsink. 1 Raptor HDD, 1 7200rpm hdd.

Anyway, i'd like to bring the temps down a little bit more and I was wondering if I should set the voltage to 1.25 via bios? Any other suggestions would be helpful. Case fans are at medium speed and heatsink does not have ULNA attached.

Thanks.

That vcore is not higher than stock. Don't change it. The high temperature is normal if you use stock heatsink. The thing is half the size of the stock cooler from old P4. It's absolutely pathetic. Get aftermarket cooler.

I am using an aftermarket heatsink, read my post again.

Isn't 1.3-1.325v range normal for that CPU without speedstep?

VID is 1.215-1.325.

Default Vcore value or VID is in shown in CPU-Z on the CPU tab.
EDIT : I was wrong. It's in CoreTemp. CPU-Z shows current voltage.

All GA-P35- boards overvolt by some amount.

It's normal for a Q6600 to function at stock below VID (my Q6600 works perfectly stable (24h Prime95) at 1.075V on a rubish PSU).

It also runs 3.3GHz (9x367MHz) at just below VID on my new PSU.

ok, do those temps seem reasonable then? 4 core average of 51C at idle. 54 51 49 50.

58 C under load.

You are fine staying under 60 degrees at load. Some people push much higher, I like to keep it under 60 with my Q6600.

@Tronic
Check to see if you have C1E/Speedstep disabled in BIOS.

The IDLE temps seem a bit high but that's that. The temps are fine under load (but it would be good to know what you mean by "under load" (Prime95 (v25.6) is a good stress tester)).

My Q6600 3.0GHz idles around 33°C/34°C/33°C/27°C (22°C-24°C ambient).
Prime95 (v25.6) load (maximum after a 24h run) 54°C/54°C/49°C/47°C.

Right, also what are you monitoring temps with?

Prime95 25.6
Core Temp
Also Real Temp. It has a default TjMax of 95C instead of 100C in Core Temp
