Overclockers Online has posted a new review on the Cooler Master GeminII

Based on my experience, the use of at least one fan makes the GeminII a top performer. The cooler should not be used passively on any modern processor. It easily beat the Intel stock cooler and also helped cool down the surrounding components on the motherboard due to its ability to accommodate 120mm fans. If two fans were used, performance is likely to be even better, at the expense of your hearing of course; however, if appropriate fans with a good air flow to noise ratio are used, there is no reason why the GeminII can't be a winner.
