• Backside cooling plate

• Arctic Cooling Sticker

The first revision used a heatsink base which was higher than the surrounding copper, resulting in less than optimal flatness. Revision two does not use this, so the surface is much flatter.



In the past, Arctic has been including thermal paste with their VGA coolers. I don't know why they are using a thermal pad now, maybe too many users messed up the application.

The thermal pad is protected by a small plastic cover. Unfortunately our sample got treated bad on its way and the pad got damaged, maybe there is an issue with Arctic's packing. However, damage this small should not have any effect on the cooling performance, if you consider that the mounting pressure will compress that pad a lot anyway.
