With good temperatures, quiet operation and the ability to cool secondary components, the Thermaltake DuOrb is a good CPU cooler for those looking to overclock a dual-core processor to respectable levels. Quad-Core processors can also overclock with this cooler, but to a lesser extent. Don't get me wrong, the DuOrb is a performer, but we have seen a couple of other coolers in this price range, around 65 US Dollars that can perform better. The sheer mass of the cooler does allow temperatures to stay consistent at idle and full load; a big plus for overclockers.
The dual 80mm fans are quiet for an enthusiast class cooler. I would have liked to have seen the fans scale a little higher in terms of RPM. This would allow the cooler to move into the outrageous cooling class, but this would have increased the acoustic footprint and put more load on the motherboards built in power circuitry.
Aside from good cooling, the DuOrb will look good with the DuOrb VGA cooler and it is easy for me to recommend both products if you are running a system with a clear case side. Both DuOrb products really complement each other in both looks and performance.
