Hey man, saw your youtube vid on fixing the Acer 5920g's 8600M GT card with the oven trick, but don't have a

Also the Arctic Silver 5 is conductive and may flow out and short things out given the amount you used to compensate for the lack a thicker pad. If it was a pastier, non-conductive thermal interface material, you might be ok for a while but I'd be afraid of a gap forming. There is a 220+ page thread about Acer MXM Models and Cards, look after page 210 or so and you will see some discussion that shows the 0.5 mm thick shim has been tested on the 5920g. My 5920g w/ 8600M GT failed the same way yesterday and I'll be ordering a shim before putting everything back in.
Also another poster has mentioned he had to use a 0.9 mm shim on page 227 of the same thread. Although it is unclear whether he tried 0.5 mm. Poster u6b36ef had said a few pages before, that w/ 0.5 mm the paste spread thin. With a 0.9 mm shim on the GPU, the thermal pads for its RAM may not contact as well, though being DDR2, the RAM may not run too hot either way. I just took a closer look at the thermal pad on the GPU part of the cooler and it definitely is well under 1mm, so I'd go with 0.5 mm. If anything, you don't get the shim, take off some of that excess thermal paste that was put on in the vid. The pad is actually very thin sheet for the GPU, 0.5 mm sounds right. But now I am thinking now even paste may fill the gap, just don't use too much, and I'd lean towards non-conductive stuff.
