**Official** Core i7 860/870 overclocking thread

[David-Duc]

Thanks a lot for your reply, cesthree. Answers to your questions:

-I tried to disable the HT, the temp goes down but I couldn't have my HT disabled, because the F@H via Linux VMWare require it .
-The Thermal paste is the one that came with my Megahalem, I think it is PK-1. The mounting is also good, double checked it .
-My system has been up for 3-4 days and I think this period of time is ok for TIM curing.
-My case is CM Centurion 5, which is 4 years old now , but I think it still meets my needs. 1 intake fan, 1 exhaust fan, 1 fan from PSU that also exhaust, all fans are Thermaltake Thunderblade 2000rpm except for the PSU fan - they sounded like a vacuum
-Idle temp. around 42-46°C.
-Room temp. around 28°C

I'm not a "suicide overclocker" and my system has to full load at least 18hrs a day so I'll leave it at 3.8Ghz. Sharing experiences and discussing problems help us leap forward , so don't be hesitate. Thank you again, cesthree.

I built 4 systems using that case for my last employer. Still running circles around the HP crap they have in the other 75% of the offices.

It's a good case, for a desktop. I am not sure if it does a great job at keeping your Megahalems happy tho.

A buddy of mine had two cases that were very similar in design. We went in halves on a hole saw to cut 120mm fan holes. Punched holes in both of them and mounted some medium-high speed fans. Made a very significant impact on his temps.

Also, have you seen this:

I am picking up some of that Shin-Etsu as soon as I find a retailer that carries the fitting I want and the Shin-Etsu so I can order from one place.

Really with the voltages you are pushing you shouldn't see that high of temps, and the Megahalems is a great cooler, which leaves case airflow and ambient temps.

I should have specified if we were talking about ambient room or ambient case temps. If it is room temps then:

28C isn't bad, but I know that 25C is ~75F, so you are closer to 80F and that is a right around what temperature my computer room gets to when I am stress testing after 3-4 hours.

If you are starting at 28C, then you really need to lower ambient some if you want lower temps in the case at the CPU.

I could be totally off base. These are just guesses, and I am not a thermodynamic engineer. Just from what I have observed.

I had to close the heat register in our computer room to keep things under control. Both of our rigs keep it warm enough anyhow.
