GA-965P-DS3 latest rescue board idles at 70C!
Nothing attached running on breadboard. standard 775 cooler double checked its on properly where do I look next?

Re: Latest rescue board HOT

let me guess.pentium d on a inadequate hsf.
had that a while back.had a real intel hsf but only about 3/4 " thick.

Re: Latest rescue board HOT

My guess is the heatsink is not flush with the cpu, it may look like its on properly but the temp says otherwise.

Re: Latest rescue board HOT

A different cooler wont help you, if your at 70C you have other issues, even a stock cooler on a overclocked Pentium D 130W will be under 70C, unless you have no case fans with a blanket over it and the room is at 100F.

Like I said before your heatsink is not flush on the CPU even if your eyes tell you it is, or you have other problems which would be rare.

Thank you for your response brethin
I have spent a lot of time fitting the cooler. I have to admit I am waiting on thermel paste but I doubt this would make a huge difference. I will let you know when I have applied it.
PS never had any on this on other 775 boards
I have also swapped the CPU

Re: Latest rescue board HOT

Since it is socket 775 double check to make sure the latch is closed all they way. I have seen where the cpu was not above the latch after its locked down and that caused the heatsink to ride on top of the latch and not make direct contact with the cpu. If that is the case here paste will help but if the gap is too great you may need a shim between the cooler and the cpu.

Re: Latest rescue board HOT

Thank you all...
I put paste on and verry verry carefully screwed down them dumb 775 legs so now we got a current system temp of 37C and the CPU running at 42C

Re: Latest rescue board HOT

Good to hear!
I knew exactly what it was, heatsink not making good contact with cpu. 99% of the time that is.

Are you saying you didn't use any thermal paste at all? That would likely make a huge difference, especially if it's a Pentium D.

Re: Latest rescue board HOT

yep. even the cheapo generic white silicone based stuff already makes a huge difference.

i usually keep a 40gram tube of the cheap generic heatsink compound around for testing, and use the better stuff for final setups.

Board has been running flawlessly for 2 days at 38C idle
