Temps for Q6700 vs. QX6850

[b1gapl]

What's the difference between MX-2 and Arctic Silver 5?

Arctic Cooling's MX-1 and 2, are a bit better than AS5. MX-2 is probably the current leading TIM....well...behind Liquid Pro.

Refer to my Battle of the Thermal Pastes link, below my sig.

nobody looks at the Sticky's anymore do they.....

I saw you're using an Ultra 120 Extreme too. What kind of temps are you getting?

 

[Andyf]

well, I run a q6600, g0 stepping, overclocked. Idle it runs at core temps of around 30/30/24/24 in ambient 20* temp. Loaded, perhaps 60/60/50/50 (prolly partially due to imperfect seating of the the thermal paste/ heatsink and partially due to the core useage). Reading around, this kind of discrepancy between cores doesn't seem to be uncommon.

I reseated the heatsink (Termalright Ultra 120 Extreme). I spread a very thin layer of grease on the processor, and seated the heatsink.

My temps are still about 47C at idle in room with a comfortable ambient temp (don't know exactly, but probably around 75F).

Any thoughts on why the high idle temps?

What thermal paste did you use?

What is your ambient room temperature?

I'm no pro but maybe the surface of the TRUE and the CPU just don't match up right. (concave-concave/convex-convex). Just an idea. Flip the true upside down and balance the processor on top, stick a light behind em. Maybe you should look into lapping them both. Pictorial HSF+IHS lapping guide!

great lapping guide.

Did you clean off the old paste before re-applying? (sorry if obvious, just askin)

I think the ambient room temperature is around 75F. It's not too hot and not too cold with a Tshirt.

I used Arctic Silver 5. No lapping. Yes, I cleaned off grease with thermal paste remover before reseating.

BTW, thermal case management has slight negative effect. When I take the side panel off, it lowers the CPU temp by 2C. I cant mod the case, in case you're gonna suggest it. =)

Andyf,

My load temps are similar but slightly higher than yours (about 65C/55C/54C/62C after 10 minutes of Prime95), but your idle temps are 10C-15C lower than mine (46C/40C/36C/43C). The temps do fluctuate some. I have seen 2 of the cores spike up to 70C, but it's not all the time.

My question is whether my load temps on the two higher cores is 100% safe, and whether spiking above 70C occasionally will affect the CPU?

For those following the thread, I already reseated the CPU with arctic silver 5. Thanks.

Please comment.
