Also if you're not using a reference cooler with the stock memory/vrm plate you need the Thermalright VRM-R1/R2 in order to keep the VRMs under 120C.

The aluminum ramsink portion of the cooler needed to be trimmed to clear the row of capacitors to the right of the GPU. The stock VRM heatsink also needed to be shortened to fit under the cooler's fan. Cooler now fits great!

21/05/2010 10:35:51KayDatXFXYesHD5870Arctic Cooling Accelero S1 R2Yes (Minor Issue)Many people have issues with the bottom right ramsink getting in the way of a heatpipe. If you aren't afraid of buying extra parts, you can buy a pair of low profile Accelero Xtreme GTX 280 ramsinks from the AC webstore for a couple of dollars, under Spare Parts->VGA Cooler.

You can get extra regular ramsinks and VRM sinks for cheap as well.

21/06/2010 06:27:50j0n3z3yMSINoHD5770Artic Accellero S1 Rev. 2Yes (Did Not Fit)Card: R5770 Hawk GPU spacers for the mounting bracket are too tall (1mm) for the R5770 (and probably other 5770's as well).

Instead of trimming the factory spacers. I made some out of 1/8" silicone tubing allowing compression of the spacers for a firm heatsink base to gpu interface.

The mounting bracket also requires trimming to avoid contact (and shorting out) several SMT components. Most notably a large SMT capactitor on the lower right side (in reference to the PCI-E slot).

For use of the VRM heatsinks,the GPU VRM's must be cut in half for proper fitment. The ram VRM heatsinks must have two fins removed to make contact and avoid touching other components.

some of the RAM heatsinks didnt stick that well but as the card sits flat in my case it's not a problem - imagine it would be major problem if the card sits sideways - you'd need to use thermal adhesive tape or other to secure some of these VRAM sinks
