Guest quipster Posted April 27, 2011 Report Share Posted April 27, 2011 Have you done everything to prevent overheating of the card, i.e. placed a copper shim between heatsink and GPU-die (same size as recess in heatsink, approx o.6 mm thick) in combination with good thermal paste (a.k.a. copper mod)?

zoxpop1980 Posted April 27, 2011 Author Report Share Posted April 27, 2011 I think you have right. The 4 screws on new card is higher then on my old card.The diference is 1-2mm. What i need to do? To buy the cooper shim? But i dont know where and if 0.6mm will be enough Quote Link to comment Share on other sites More sharing options...
Guest quipster Posted April 29, 2011 Report Share Posted April 29, 2011 Aluminum will also do, as it features roughly the same thermal conductivity. The difference in temperature compared to copper would not be measurable. Yeah, just take some aluminum, roughly 1 mm thick and cut out a rectangle with the same size as the recess in the heatsink. Then round over the edges with sanding paper. Apply thermal paste on both sides, put the shim in and mount the heatsink onto the card.
