Temperatures & Overclocking Intel C2D E 7500 (Wolfdale) ..?
Ok.. I have a Intel C2D E 7500 (2.93 GHz, 3 MB Cache, 1066 MHz FSB, 266 MHz * 11.5 (Multiplier)).. I am going to overclock it. I pumped the FSB up to 333 MHz and the Multiplier remained at 11.5. The system started but when I ran the Prime95 Torture test and it failed on 1 core in about 15 minutes..

I reduced the FSB to 315 MHz * 11.5 (3.46 GHz) and ran the Prime 95, it ran for 10 hours, without errors..

Now my question is the ambient Temp in room is about 15 Celsius and the Prime 95 caused a maximum temp of 70 Celsius stable at 67-68 Celsius.. In summers, temperatures go up to 45 Celsius here.. I am currently using the Stock cooler and no Thermal paste ( I am getting the Arctic Cooler A5S).. Do i need a custom cooler ??? Also can someone tell me whats the safe temperature for this Chip...

Also running the Prime 95 for stability was necessary,although I am aware that no Program can stress the CPU to 100 % for hours together. But I think having a stable rig is more important, and anyways courtesy Intel Speedstep the CPU never runs at the full speed even while watching a HD movie the multiplier remains at 6 ..

ps: Please don't tell me that I am voiding the warranty, I know it.. If the chip gets fried, I'll get it exchanged.. Intel guys can't still find out if the Chip was overclocked and that's the reason it fried.. Cheers Intel ;-p

You should keep the max temperature under 70C.

And if you are overclocking that high, you need better cooling.

Here are two under $50 heatsinks that are pretty popular:
Sunbeam

Xigmatec Dark Knight

They both require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.

And here's a good budget cooler:

And better cooling may...

And better cooling may let you overclock a little higher.
