Is Thermaltake TG-2 safe for GPU die?
Yesterday, in a moment of brilliance, I decided to deep-clean my GPU heatsink. That included removing it from the board and in process, wiping off the stock thermal compound. I had a tube of TG-2 lying around, and applied it when putting everything back together. But when I put the card into my PC and booted it up, it dawned upon me that the shiny reflective surface was not actually a heat spreader, but the GPU die itself. And the small bumps around it were exposed capacitors. Also, a quick google revealed that TG-2 has "low electrical conductivity" but not "non-conductive".
So, I immidately opened everything up, and saw that there were some spilling of the TG-2 around the die, but they are all at least 1mm away from any capacitors. Satisfied, I wiped it and re applied the paste exactly as I did it before. Put it back in, booted up again, and it's running fine still.
My question is, as my GPU hasn't blown up yet. Is it safe to keep the TG-2 in there, or should I go out and find some Arctic MX-4 ASAP?
On a side note. I did some performance testing.
Note: The GPU is overclocked and all tests are done with the fan speed manually set at 100%.
Before cleaning/changing thermal compound my GPU temp went up to 89° C after running OCCT GPU test for 20 minutes.
After applying TG-2 and doing few 5 minute load cycles and a hour of light gaming to cure the paste, GPU temp went up to 84° C after running OCCT GPU test for 20minutes.
After shutting down the PC immidiately at high temperature during the test to introduce a rapid cooldown to the paste, now the GPU temp stabilizes at 76° C and doesn't go up.
Question: Did the thermal shock really cure the paste and improve performance so much, or did my GPU somehow started throttling? Note, the OCCT GPU test FPS is still same as the first and second test.
Update: I've found out the temp drop from 84° C to 76° C was not because of the thermal paste. It's because, for some reason my GPU's VDCC stopped going up to 1.158v under stress with OC and now only goes up to 1.084v. I don't know how that happened.

I think Semi-Conductivity actually helps the heatsink, i mean if you think about it. There's a resistance value depending at high temperature, if it's that much then it's ok meaning there isn't much resistance to the conductivity. Semi Conductive material works better that way but depending on the temp so in conclusion i guess it did improve on your GPU
Also on another note, where do you find Diamond Paste?

You mean "IC Diamond 24 Carat Thermal Compound", with 92% pure syntheic Diamond? Is that even available at BD?

How much will you gain by ocing from it? Just sell it and buy 2nd hand gfx card like 7870hd or gtx 660 for 10k around. Buy nvidia card, somewhere I heard that nvidia cards give good fps with weak CPUs compared to amd ...???
I'll buy one, on my upcoming whole system upgrade after July, don't worry. And I have been running this one OCed for a long time now. I just wanted to get the gpu temps lower again like before.
