Corsair Dominator 4GB PC2-8500 review
 

Put simply, Corsair's TWIN2X4096-8500C5DF is a great kit. The DHX cooling system is still the best I've seen to date, cooling both a specially designed PCB and the ICs themselves. BGA based DDR2 modules conduct quite a bit of heat back into the PCB, so this is a very intelligent design that will likely prolong the life of just about any IC under the hood. Corsair's included "Airflow Fan" has also proved to be a very quiet and effective cooler that complements the DHX system nicely. The combination of the unique cooling solution and black PCB also make this a great looking kit.
