The Scythe Orochi's sheer size had expecting impressive performance. However, size is not everything. I believe the Orochi's performance is seriously hindered by its "passive" mode and Scythe's option for such a low speed fan. The heatsink became extremely hot under load tests proving that it does have good heat conducting abilities, but the ability to then remove the heat from the heatsink proved the be where the Orochi fell behind. As the stress test went on the temps began to rise almost at a constant pace until they were too much for the heatsink to handle itself. Paired with a high CFM fan (conveniently I stepped on my 88cfm yate loon which I usually use for this sort of situation) I believe the Orochi could be a contender in the performance market. However its massive size and weight make it almost non-practical to be used as an everyday cooler.

Pros
• Heat conducting ability
• Can be used passive under load heat situations
• Absolutely silent, even with provided fan
• Great base finish

Cons
• Overpowered by high heat output CPU's
• Stacked heatpipes
• Low CFM fan, while purposely meant to be low CFM, is simply too low
• Size and weight

Special thanks to Scythe for providing this heatsink to us for review!
