Now "maybe" the 7970 is better but that would mean they are finally getting their act together ONLY on the 7000 series because 5000 & 6000 are horrible. Since I am curious 1 BTC open ended bounty to the first person to post a high resolution screenshot of 7970 right after heatsink is removed.

Here's a pic 7970 Heat sink (bottom) and the 7950 heatsink removed from production cards.

P.S. The Sapphire 7950 has a vary crappy heatsink fan combo IMO . I have a HIS 6950 card with this same heatsink / fan and it sucks as hell.

Since everyone seems to be posting their favorite thermal goop benchmarks, let me hop into the fray:
thermal compound roundup @Hardware Secrets
AS5 kicking some major butt here.
On a more serious note, the Arctic Silver 5 needs up to 200 hours to fully cure, RTFM at leisure.

The TIM is machine-silkscreened onto the heatsink as a powder, which then melts and re-hardens as solid when the board is run. No TIM you can buy off the shelf is more efficient than what we put on the 7970.

Yeah I don't care what a marketing guy from AMD says. I have opened the cards and seen with my uses they look like ass. Literally the worst TIM application I have ever seen which is kinda hard to believe given we are talking about ultra high end prices.

And, my 6970's had excellent TIM application too...

2. the paste on the 7970/6990 is the best you can get.

Lolz. The paste on my (granted only one) 6990 was the worst pieces of shit I have ever seen, plus it was applied so thick it looked like someone was making a peanut butter and thermal paste sandwich.

Every 5970 I have opened up looked exactly the same and I doubt the 7970 is any better.

1. As5 is horrible paste by todays standard and isn't ideal for use on gpus.

Using AS5 on a bunch of 6950s with good results. The trick is not to put gobs of it and prior cleaning of the mating surfaces with IPA.

I had decent results w/ AS5 but there are likely better TIM today especially for use on a GPU. I just kept using AS out of habit. You are right. TIM higher thermal conductivity than air but worse than metal. Putting too much on acts as an insulator trapping heat in.

It should be thin, very thin layer. If someone is unsure it is best to do a trial run, where you apply it, attached heat sink, then remove and take a look at how thin it was. Be sure to clean and re-apply.

I opened up my 7970 to put on new thermal paste *(Artic Silver 5) and now temps are 10C higher.. wth? Do I have to wait until it's cured?
