Should I reseat my heatsink?

post #1 of 6
Thread Starter 
Specs are below. Ambient temp is 24-25c. CPU-Z reads 1.376v but the voltage is set to about 1.42 in the BIOS(so I'd trust that). My CPU is clocked to 3.6GHz.

Load temp gets up to around 61-62C (according to Core Temp) on Cores 0 and 1, and 58-59c on Core 2 and 3.

What do you guys think? When seating originally, I filled in the gaps with MX-2 (as suggested by many), and then put thin lines across the heatpipes.

Let me know.

Those temps are alright, from looking at this temp guide you are in the "warm" area. Safe would be best, but with that vcore and HSF I think they should be a little lower. Not sure as far as how you are supposed to apply the TIM on that heatsink though, since it has exposed heatpipes.

Also, your BIOS reports the vcore that it is trying to give the CPU but under load the voltage will "droop" a bit, so your cpu-z reading is correctly reporting your vcore.

From your description of "filling in the gaps" it would seem like it is easy to apply too much TIM, it might help if you could remove the HSF and take a picture of the IHS and heatsink base before you remove the TIM.


EDIT:
I'm sorry, I was looking at QX6700 not Q6700, anything under 65C should be fine as far as temperature on each core when read from core temp.

When I said that the vcore is about 1.42v in my BIOS, I meant that the BIOS is reading it as that. I find it hard to believe that I'd have that big of a vdroop.

I applied thermal paste as recommended here: http://benchmarkreviews.com/index.ph...1&limitstart=5

Okay so, as prime continues to run, my load temp continues to rise. Is this a sign that my heatsink is not dissipating thermal energy quickly enough to hold a constant load temperature?

And at a voltage (according to CPU-Z) of 1.328v, my load temp is 61c. I just reseated, and this still seems too high.

I've tried every thermal paste method suggested for quad core with this heatsink. Anyone have any info, or are these temps just normal?

No, it just means that it hasn't reached the equilibrium temperature where the heatsink is dissipating heat at the same rate the CPU is generating it. You just need to wait longer.

You may want to consider lapping your heatsink and IHS (the cover on the CPU). And make sure that your case is getting proper airflow.
