Cooler Master Hyper 612 PWM and GeminII S524

Though the GeminII S524 isn't a hugely strong competitor in these tests, it is by far the smallest of the comparison models, and truthfully, it serves a different purpose. The Hyper 612 PWM is meant to be big, bulky, and a powerhouse performer for keeping your processor cool. On the other hand, there's no way that this monster would EVER fit into a mini ITX case. So, if it's not some large tower heatsink and still performs far better than the stock cooler, then something like the GeminII S524 would be a good choice.
