E6400: High Temps at 2.6GHz?! - Page 2

post #11 of 38
Thread Starter 
So,
Do you think I should be done with it and buy some expensive water cooling?

I am not giving up overclocking this!!

If you have the extra money, then yes. But, you might want to try a tower cooler first. It will cost less, and will out-perform many mid-level water cooling setups. Lapping the surface of the IHS on the CPU will help, but will VOID your warranty. Lapping the HSF base is also highly recommended.

Some good tower coolers: Tuniq, Scythe, Noctua. Some have a 90mm version, but I would stick with the 120mm size. Also, check to make sure that you have enough space in your case to accomodate one of these monsters.

I was running @ 3GHz with 1.28V. You could probably drop it to 1.25 for that OC.

Theres definately something wrong with your temps.

Possibly too much or too little thermal compund.
Possibly, the heatsink isnt on tight enough (im not sure how its mounted).
Try PC Wizard 06. I use that for my core temps. If that doesnt work for you, use Speedfan (although it only provides one core temp)

TAT (Thermal Analysis Tool) is an excellent utility for the C2D:

It reads both cores, and has some Stress Test options.

Thanks. I maybe used too little thermal grease.
I don't think those big towers will fit in my case... I'll have to measure.

Core Temp and TAT read the same. 50C when I disable those options in BIOS (throttle, variable voltage etc) at stock voltage, frequency...

Ok, I'll try that now.

My friend is coming 'round to help me solve this problem. I'll keep this thread updated...

Edit: Booted into windows at 1.28v @ stock FSB everything seems fine. Need to test.

What is the "right" amount of thermal grease? I cleaned off the stock grease good and put a very thin (but completely covered) layer of silver on. If anything temps are now worse by 1C. So either the stock thermal compound works fine, or I didn't put enough compound on. I'll be reseating the HSF again in the near future (stock fan)....

I think that you used too much. Try a dollop the size of a grain of uncooked rice.... or a very thin vertical line (.5m x 5mm) that will run between the cores. If you have lapped components, then try half the amount. Remember the "cure-time" involved (sorry for sounding like a broken record). In addition double-check the tension of the HSF against the IHS. It should not move.

I'm currently set at 333FSB - 48C idle. I'll see how much I can go at this voltage.

Thanks. It seems one of those big cooler towers will not fit in my case. So I'll be getting a new case and a Tuniq tower.

mines perfectly stable at 3Ghz using 1.32 volts. You might be able to lower vcore some more and maintain stability at that clock.
