Dual core temps differ

post #1 of 18
Thread Starter 
I was just reading a post and they mentioned a program called "Core Temp".
I downloaded it and ran it. This is what I got. Why the big difference?

CoreTemp works great... provided you don't have Brisbane.

Please do try CoreTemo 0.95.

It is normal for them to be at different temps every moment, but that's normally usually 2~4C. 10C difference, I find that strange.

Run Orthos for 2 minutes and see if the temps raise and come closer to each other. If they stay +10C in difference, I would remount your heat sink.

Yep, totally normal. It's due to the thermal interface material being unevenly applied under the integrated heat spreader. Nothing to worry about sir!
On my 3800+ X2 I had a differential of 13C at times.
If temps are that big of an issue when you are trying to OC higher, then remove the IHS. This will fix the issue, but you are taking a massive risk of destroying your CPU if you mess it up. THen again you can replace it for <$100!

Sorry guys, it has nothing to do with the HS. It's simply the way that the crappy TIM was applied. WAY too much from the pics I've seen

I d/l Core Temp 095 and ran Othos. They are staying 10 degrees apart.
I guess I will try to reinstall the heat sink and see what happens. I'll report back.

Thank You

Do you mean that the Arctic Silver is not spread evenly? I even made a small rubber squeegee for it!!
I will await your more knowledgeable reply.

Have you check the HS for a true flat surface?

Ive tried to reseat my heatsink many times and I still get the very large temp difference between my two cores. As Binormalkilla stated some of these dual cores just have a poorly seated IHS. Thats why Im going to be removing mine.

No, I have never done that. I never felt the need to. Are you suggesting that it needs to be lapped? I think that might be over kill as when I run Othos for 6 hours the highest temperature is 58c. What do you think? Also I play no games or anything that is really intensive.
Thanks Irv

If it's a rough surface lap it!
Those that are rough no only do a poorer job of thermal transfer, they are usually not flat!
Mark it with a blue or black magic marker then do a few passes in all four directions then inspect it. For example, my BT, very rough and it had a shallow spot just offset to the center!

Its worth the effort, cooler is better

The best way to test for a flat surface is to get some graph paper and lay the HS on top of it. Look at the grid pattern and see if it's distorted (curved) instead of straight lines.
I guarantee that lapping wont' fix the temp differential. I was at the same point as you last year. Trust me.
Honestly your temps are fine. If those are idle temps then they are a little higher, so you may want to lap for that reason, but reseating the HS won't change that at all.
