Guess you didn't read my link. If you did you would see that with a great contact mount(which is rare), it actually does rather well.
Guess Skinneelabs didn't read Arctic Silver's manual. That TIM requires up to 200 hours of curing which they never bothered with. A shame really.

I don't recommend it for use on GPUs mainly because its a capacitive paste and shouldn't be used anywhere near traces or SMD's.
Never have I managed to use quantities excessive enough for the goop to squeeze out from where it belongs and onto the surrounding components. Therefore, I can hardly accept that as a valid argument against that paste. That having been said, it's a valid data point.

Remember, we're trying to help OP, not argue about world's best TIM Wink

People do use paste on the memory modules and vrms depending on what waterblocks they use too.

I don't see how that is pertinent to OP's issue?
+10°C may suggest OP botched the application somehow but we'll only know for sure when the TIM has fully cured.
OP asked a question whether he should let the TIM cure. I addressed this question directly by linking to manufacturer's recommendations.
He probably needn't have touched the heatsink in the first place but that's another sack of ferrets.

You won't get a 10c decrease from as5 curing.. It's more like 1-2c tops...

...which is precisely why I said that might mean he botched the TIM application somehow and that he needn't have messed with the card.
That's pretty consistent with what you wrote in your first reply, isn't it?

Roadhog, I'll just call it a night, ok? We're going way OT with this conversation and there's precious little to be added.

hmm.. this is the first I've heard about the curing process (I know, I know, RTFM) can you use the card/cpu while it's curing? Should you put the heatsink on and let it sit for 200 hrs unused?

Quite the contrary, in fact. Curing progresses faster in high temperatures. Just use the machine like it's supposed to be used, the temperatures will slowly drop by a few degrees.

No it requires heat.  So you use the card but expect temps to be higher for first 200 hours.  BTW all TIM have a curing time but most acheive lowest temps in 2 to 10 hours.

Some people recommend putting the chip under a reduced thermal load during curing time.

My MSI 7970 overheats while mining unless i set the fan to manual and undervolt the card to 1.03V from 1.175.  I would love to reapply thermal paste, but dont feel comfortable taking it apart.  I recently did my 5870 and temps dropped 23C plus now the fan only runs at 36% to keep it at 66C
