Arctic Cooling Freezer 64 Pro and Arctic silver.

I've changed my motherboard, so I had to remove my Arctic Freezer so as I could move my CPU to my new board. This meant that I had to clean off the pre-applied thermal paste(is it MX-1?)from my CPU and Arctic Freezer, and use Arctic Silver 5 when I installed them in my new mobo.

The question is, should you apply a little bit more AS5 to make sure there's a layer between the whole of the CPU and the bottom of the heatsink?

I ask because in my new board my CPU idle temps are higher than they were before I made the change over. The bottom of the heat sink isn't smooth on the Arctic Freezer, it's quite rough, so I wondered whether you needed to apply a little extra AS5 to get into the small grooves. Also, the pre-applied thermal paste on the Arctic Freezer covers the whole of the bottom of the heat sink and I thought whether you should make sure AS5 is applied in the same way to give better heat conductivity?

Any advice please?

Thanks for replying PARUK

I've never heard of the term lapping, but I get the gist of what you meant. I think I'll just remove the HSF so as to re-apply some AS5,making sure it's seated properly. It seemed pretty solid when I fitted it though.

I didn't use any TIM remover originally, just kitchen roll and cotton buds to remove the gunk and then wiped thoroughly with a soft cloth. I've just bought some TIM remover, so I'll see after using that if there's any improvement.

Thanks again, dagwoood.
