Delided, laped 3770K, temp drop 30+, thanks Idont and Ido CARE

So why do they put lids on these things if it makes your temperatures so horrible?

There is an Ido?

Yes, I did lapped HSM inner side as per Idocare idea. All other amazing info came from IDC experience and walkthrough.

Checkout the following thread 😉

Bare-die testing: A delidded 3770k, an H100, and 9 different TIMs

But what I'm worried about is after couple of months if I have to re apply it or not, if I'm using arctic silver that I have.

You are referring to the "pump out effect" and yes you should avoid AS5, NT-H1, MX-4, etc based on this concern.

IC Diamond and liquid pro/ultra don't have this issue.

Great stuff. If Haswell has the same crummy CPU to IHS TIM, there is hope for us 24x7 overclockers.

Does the amount of hold down pressure have a large effect on the "pump out effect".

It plays a role but not in a primary capacity.

Pump-out comes about because of thermal expansion and contraction as the processor and IHS heat up and cool down.

In the schematic above I depict the TIM as uniformally being pumped out across the entire surface of the CPU, the reality is that it only forms little air-gaps in localized places across the die.

Thank you that saved much reading
