No idea how much, one guy told that one dot on IB dies IHS enough, removing is like ordinary paste's i think.
Also what i think, maybe i am wrong, is that these paste's are only good on directs dies, like on HD 7900 cards, they dont work well on heat spreader.

Thanks for the info, I really want to try and find out more about this TIM. I always thought you had to lap it off upon removal though?

Not worth the risk or effort in my opinion. 

The thermal grease they use to begin with is actually pretty decent and the application is well enough. 

 

Though I'm not entirely sure for non-reference cards.

Np mate.
About removal, maybe you are right, didnt find any info about removal though.
What i also think that this paste might not be good with coolers with direct pipe touch. Like on my DCII, but who knows, maybe i am wrong.
Also one question, do you experience artefacts when you touch 73C?

I would just love to get rid of the high temps on my top card. Top card can hit 80c at times when overclocked, but if the paste can reduce it to around 72c or lower, that would be brilliant.

Just thought I would bring this to the attention of reference HD7970 owners. Very surprised.redface.gif

I don't see any issues even when I've ran briefly at 92c. My cards are not bothered by heat or anything. They are very firm. I have a limit of 80c. I average at 75c in games when overclocked on auto fan.

The GPU can safely run up to 95c before it's throttled down automatically. 

Why is one card hotter than the other? 

Airflow more than likely. 

 

Changing the thermal paste is likely to result in getting worse temps (usually due to improper application).

It was a defective card and should be treated as such. 

Doesn't mean if you got another card it would behave the same.

Top card sucks hot air from the second GPU.
