why will you guys not allow people to RMA cpu's that had a TIM besides the shin tu estu stuff on it??? even other non-conductive materials arent allowed...why????

Before someone brings up the comment that AC3 or any other silver compound is not conductive under their multimeter.

It does have metal particles, with space between, So:
A: It's not very conductive.
B: It is VERY capacative. (Acts like a capacitor)

Silver compounds change the impeadance and capacitance of the die and die package (If spilled onto the package)

With RF freqeuncies of 800mhz, 2ghz, etc, Silver compounds can become very conductive. (As a capacitor passes AC readily)

shin tu estu does not, as it is not metalic.

With all that said, the new processors of course have a heatplate on top.
This eliminates the worry of impeadance.
So you could use Silver compounds.
But you will still get 'pump out' over time, where the paste is forced out the edges.

shin tu estu changes from a solid to liquid when hot, it won't pump out as if it does reach the edge it will cool and block up any cracks where more paste may push out.

If you watch the heatsink installation videos, I think they say grease is ok for temporary or testing purposes. Long term use, PCM should be used.

what about Ceramique then?

Ceramique is ceramic and should be ok.

But it will still suffer from pump out over time.

so if your cpu died from natural causes and there's shin etsu on the cpu instead of the tim, then the warranty is not void?
I'm using the shin etsu G751 paste cause it gives me better temps with my xp2600
Lucky we can get shin etsu here in Australia
