I'm installing the DuOrb CPU Cooler on my socket AM2 SLI board, one of the configurations that Thermaltake cautions may have an interference problem with the first PCIe slot. Luckily this Biostar board has the socket oriented in the standard direction, so that the main length of the cooler will run front to back across the board, rather than longways over the card slots. The optional backing plate was not needed in this case as the stock plate was already threaded for the mounting clips and installation was as simple as unscrewing the stock bracket and screwing down the two provided clips.
After centering the cooler over the CPU and laying the bridge across its base, two spring-loaded thumbscrews are tightened on either side. They are also cut for a standard Phillips screwdriver, and it appears I may have used a little too much force in tightening them down as the clip began to bend under the pressure. No matter as the springs should provide the proper tension between the base and CPU heatspreader anyway. There were no interference problems with any components surrounding the CPU socket. I had enough room to remove the memory DIMMs from their slots and reinstall them with the DuOrb in place. Although the rear DuOrb fin section did rest lightly on top of my mosfet cooler, it did not cause it to sit unevenly.
Let's complete this review with some testing and final thoughts.
