"Thermalright set out to pack the performance of a 120mm cooler into a 90mm package. With the Optima-90I, it looks like they've done just that. The cooling is very good with the 90mm fan and the package is relatively compact. As always, the workmanship is outstanding the mounting is not too difficult, though a bit bothersome for AMD users."
