Hey forum,
I just took apart my Sapphire 6870 with the stock reference cooler to apply some new thermal paste. There was a crap load of thermal paste on the GPU before where it had spilled over on all 4 sides. I cleaned it all up along with the heat sink with some 70% alcohol wipes and a lint free cloth. Then I used the simple dot method on the GPU die with some Arctic Silver 5 Thermal Paste, then reinstalled the heat sink and cover.
With an over clock up to 900 MHz on the core and 1100 MHz on the memory, the stock temps were about 55 degrees Celsius at idle and 82 degrees Celsius under load after 20 minutes of FurMark 1.8. After changing the thermal paste, the new temps were only 48 degrees Celsius at idle and only 74 degrees Celsius under load after 20 minutes of FurMark 1.8
So to summarize, after putting some Arctic Silver 5 thermal paste on the reference cooler on the 6870 and with a 50 MHz over clock on the core and the memory, the temperatures dropped by 5-10 degrees Celsius.
Has anyone else tried changing the thermal paste, and if so, what temperature changes did you notice?
