Hey All, I'm about to install a heatsink on a GPU for the first time, never actually done it with the CPU either, and i have a question. I'll be installing a TT DuOrb on my 8800GTS 512 and i'll be using the Zalman STG1 thermal compund due to ease with which it can be applied. I already took the card apart, cleaned the GPU itself as well as the RAM chips using Arctic Clean 1 & 2, installed the RAM and VRM sinks and now want to install the Orb itself. Now i'd like to know if i need to apply the STG1 grease to both the GPU and heatsink or only to the GPU? From what i've read on the web only the GPU needs the grease, however according to Zalman it needs to be applied to both: http://www.zalman.co.kr/ENG/product/Product_Read.asp?idx=221 Can someone clear this up for me? Anyone here used STG1 on a GPU?
