10c temperature difference between cores

post #1 of 17
Thread Starter 
I have a 2600k overclocked to 4.5 ghz, and I noticed the temperature difference between the cores was consitently at about 10-12 degrees. I have an h100 with the stock thermal pad. Even when at stock speeds, the 2600k has a 10 degree difference between cores. I was wondering if this is a faulty temperature sensor, bad thermal pad, or just normal.

This normal means that either...

1 - Bad block mounting
2 - Uneven Block
3 - Uneven CPU

Try getting a flat blade and putting ontop of the copper H100 block, is the contact surface flat? What about across the CPU itself? Is it flat? Try remounting the block afterwords

It can happen sometime. It could be the factory IHS not well seated, nothing you can do about it, especially if you tried to remount your cooler.

You should tyr to remount with better thermal paste than the stock one. Clean with alcohol.

The only problem is I don't have any thermal paste on hand for when I reinstall it. I had an h60 on my old computer, and when I took that off the thermal pad was too damaged to reinstall the cooler without applying new thermal paste.

As soon as you remove a cooler, its BEST to clean the old paste and replace it.

Can you find a store close with Computer parts, they usually have TIM in stock under 10$.

Its really not recommended to re-use old thermal paste wink.gif


Since you have a i7 2600k (1155), the grain of rice method would be appropriate. Put the perfect amount thumb.gif




Or line method

Well, the only store near me is a best buy, and I wouldn't trust anything from them. Any recommendations on a good thermal paste?

I use the Noctua NT-H1.

There are many top Thermal Paste, they all come to a few degrees difference in performance (even decimal degrees) thumb.gif

Does it spread evenly? I have had too many experiences where the paste just doesn't spread out at all.

You can get Arctic Silver 5. Very good product, always spreads evenly.

Maybe you'll have to remount twice to take a feel of your paste.

My 3930k is a huge CPU with huge heat spreader, I had to mount it twice to be assure of the good spreading

I did this on my 3930k.
