Just something I thought worth sharing.
TL: DR - If your GPU is running hotter than you like (even at stock), or you would like to use lower fan rpm to reduce noise, then a quick 5 min of TIM repasting job might just do the trick for you.

Recently I got a MSI TwinFrozr 7850 with my new system, and proceeded to do some stress test.
** OCCT GPU Test @ 1680 x 1050, Shader Complexity 8, STOCK setting (860/1200)
- Without FPS limit, the temperature shot up to 104 C in under a minute, and proceed to oscillate between idle and load clock speed due to temperature constraint
- Had to limit FPS to 30 to run stress test, temp maxed out at ~86 C at 100% fan.
I was a bit disappointed at the thermal, and how loud it was at 100% fan. In games I had to force vsync and/or lower some setting to get it to run at reasonable temperature & noise level (I try to keep it below 90 C with a modified fan profile).
Then I thought, this card should be able to do a lot better, let me check the TIM... And lo and behold, the factory pasting job was atrociously thick and the screws were not very well tightened (low mounting pressure).
I cleaned it up and repasted using a basic TIM that came with my Hyper 212+, nothing fancy. Evenly tightened the screws then retested it, and the result was markedly different
** OCCT GPU Test @ 1680 x 1050, Shader Complexity 8, slight OC same voltage (1050/1450)
- The temperature maxed at low 70's with fan under 50%, running at close to 80 fps
Now I can run it with lower fan profiles for nice temp and low noise. I am amazed by the difference, it was like 2 different cards.
