Cooling mod Mk2
I cannibalised an old Palit Twin Fan GTX 570 heatsink. Now the core backplate + VRAM gets solid copper block cooling. Temps now hold steady at 60 degrees when running Supo 8K. Everything else doesn't break 55 degrees. Basically an additional 10 degree improvement on the Intel HSF mod.
I'm taking delivery of a dead Quadro Single slot GPU in a few weeks, cant wait to see this thing with a sexy blower on top.
