Prolimatech PRO-PK3-30G Nano Aluminum High-Grade Thermal Compound in 30 Gram

Pros: this stuff is incredible the video card i installed this on is a
EVGA GTX 660TI FTW signature 2
the stress test im using is evga oc scanner furry/tessy test with room tempature at 70f
with stock thermal paste max temps after 30 minutes was 74/75c- evga uses a pretty decent TIM
i switched to antec nano diamond formula 7 and dropped to 70/71c
got this stuff in today immediately installed it and after 30 minutes temperature reading was 67c
this stuff blew me away i was expecting 1* maybe 2* drop
im more then satisfied with this

Cons: newegg only has the 30gram tube

Other Thoughts: well worth the price
cant wait to put it on my cpu
only reason i havnt changed my cpu TIM is because its water cooled

Pros: It dropped my temperatures by 8-12deg/C and was simplicity to install. Takes no burn in time at all.

Cons: Newegg didn't have anything smaller than the 30gm. tube so I had to buy a 5gm tube elsewhere.

Other Thoughts: I was using Arctic Silver 5 on an AMD 945 and a Scythe Mugen cooler and I switched to Shin Etsu X-23 which dropped my temps by 4-6deg/C. The Pro-PK-3 dropped my temps a further 8-12deg/C from the Shin Etsu. I'm now running a 965 OC'd to 3.9 with the same Mugen cooler and after 5 hours of Prime 95 I never break 29deg/C over ambient. Thats only 51deg/C. I was getting as high as 72deg/C with Arctic Silver 5 running the same Prime 95 test.
