Thermaltake DuOrb GPU Cooler
 

For enthusiasts, stock coolers just never cut it. Period. It
doesn't matter whether it's a video card, a CPU, a motherboard chipset,
or anything that puts out a decent amount of heat. After-market
heatsinks and other cooling solutions have become a huge market. One of
the bigger cooling issues these days is graphics cards. Even the big
beefy coolers you see on the GeForce 8800 series rarely perform as well
as they look. Many times the performance can be radically improved
simply by removing all of the thermal paste and using a compound like
Arctic Silver 5 and ensuring good contact with the GPU, but sometimes
not. This is where Thermaltake steps up to the plate. Their newest
incarnation of GPU cooler is the DuOrb CL-G0102, but does it perform well?
