Q6600 B3 Running High Temperatures at Stock

[SiNeX]

Hi guys,

I have read around alot of the threads on the forum regarding the Q6600 and generally see that it looks like I have some serious temperature issues with my setup.

My system specs are as follows:

Q6600 Revision B3
4GB HyperX DDR2-800 RAM
Asus P5K Deluxe Motherboard Bios Rev. 505 Beta
XFX 8800GTS 640MB
Antec P182 Case (1 Top, 1 Rear Exhaust, 1 Lower, 2 Central (cooling graphics card)
- Tested with original Antec Tricool Fans on High Setting in all fan locations
- Tested also with 5 replacement Noctua NF S12 in all fan locations
Thermalright Ultra 120 Extreme (lapped to a mirror finish) with a Scythe S-Flex SFF21F
Artic Silver 5 Thermal Compound (have Shin Etsu X23 7783D and Liquid Metal Pro on order)
Windows Vista Ultimate 32 bit

Tested using Core Temp 0.95, Speed fan 4.33 (offset +15c) and Prime95 v25.5 for minimum of 12 to 24 hours at a time over several weeks. There was no overclocking done just ran at stock speed with Speedstep off.

Temperatures are as follows (Ambient room temp 23-25c)

Workbench (no case):

Idle: 36-42c
Load: 56-65c

Case sides removed:

Idle: 38-45c
Load: 56-63c

Case closed

Idle: 44-48c
Load: 62-70c


I have seen alot of people overclocking this processor to 3ghz with lower temperatures than I get with a stock setup so I know there must be something wrong somewhere.

What I have considered and tried to look it to was the mounting of the Mounting Ultra 120 - I have tried a penny, a coin that I drilled a hole out big enough for the screw head, metal washers and also a teflon and rubber washer still with not much difference with the temps above (these were probably the lowest achieve so far).

I have tried differing amount of AS5 from the thin line across the middle as suggested by AS to rubbing it into both surfaces to minute traces to a thick layer. The heatsink itself is lapped to a mirror finish and is flat, although I am sure the Q6600 is not with the razor blade test so I have considered lapping that also but am relectant to void the warranty.

I have a few options left - I still have the stock Intel heatsink, I have another Ultra 120 extreme on order for another machine which I will try unlapped to see if it makes any difference with the concave / convex issues. I have a boxed Zalman CNPS9500 that I could try or I considered a Tuniq 120 Tower - I also have some Shin Etsu X23 7783D and Liquid Metal Pro on order but expect that the issues won't be fixed by a new thermal compound.

Any more ideas or comments would be appreciated as I am running out of things to consider

TIA

I have Q6600 (G0) running on a P5K-E mobo, Antec P150 case, TR utltra 120 extreme. My ambient temp is about 24C. the system is currently running at 3.2GHz. My temps are idle 38C and orthos load 65C - all fans on low, 60C - all fans on full. looking at your temps the problem looks like your case airflow. What speed is your rear exhaust fan running at. With mine I found that this actually made a bigger difference to the CPU temp than the cpu fan did. Maybe try a faster fan on the back. Doing other stuff may help but I think trying to exit more of the hot air out of the case will make the biggest difference. I have scythe s-flex fans (1600rpm) on both the CPU cooler and rear exhaust. I also use an Antec spot fan to blow on the memory voltage, I discovered that this also has a cooling effect on the cpu as its in the path of the airflow.

You could also try dropping the Vcore voltage a little to see if that helps, though I know that B3 are power hungrier.

Also I used MX2 thermal paste but I read with AS5 the mounting spreading technique is different for a quad than for a duo. I think basically it is applied the other way - there is info on their website.

Your temps are just fine and normal. To clarify, your issue is with case air flow... However, even a good airflow case will be around 5c higher than ambient. So, shoot for a case temperature of 30-33c and you should idle high 30's to low 40's.

Try to flip your top fan around so it's an intake. I did that with my P180 and noticed a decent drop in temps.

Those temperatures are alright. My q6600 at 3.15ghz at 1.375 vcore gets to 80-83C with case closed and 77-80 with case open. (this is with 30C ambient room temperature) I'm using the ultra 120 extreme unlapped. (2 fans) My case airflow was really good, but it got worse since i put in 6 hdds a GTX etc

I dont know how people get those low temps but there must be something wrong with their readings or my q6600 heat spreader is concave. I checked my friends quad with a big typhoon, and he gets 79c (2 cores) and 68C (other two cores) running everything stock. Which leads me to believe that the temperatures are fine.
