Do you reckon, the Ivy Bridge processors are more likely to have thermal interface issues in the course of the next 10-15 years? Or is it dry-proof?

I didn't read all of this but was overly impressed with the presentation and amount of work. I just chimed in to give a on that alone!

Great read! Well done as always IDC.

When I scraped the original stock CPU TIM off of my IB CPU and from the underside of the IHS it very much had the consistency of one of those thermal-mat pads that get used in laptops and such.

It had every appearance of being very durable and not likely to be going anywhere anytime soon.

I even attempted to reconstitute the stock CPU TIM so I could test it as a HSF TIM, but my efforts failed as the stuff simply was not agreeing with the notion of being soluble in IPA (and I wasn't about to try anything less human-friendly given that my two children and wife occupy the same house )













Based on my experience with this stuff, I'd say (1) it has comparable thermal conductivity properties to that of NT-H1 and MX-4, (2) it is essentially a solid-pad that is not going to dry out (it is already "dried out") or get squeezed out from the so-called pump-out effect.



(incidentally, IC Diamond claims it was designed for and proven to prevent the pump-out effect, I have not verified if this is true for our application though)
