Hi Tech Legion has posted a review on the Thermaltake TMG IA1 Heatsink

Thermaltake's TMG IA1 looks like the Hulk. The TMG IA1 by Thermaltake may look intimidating at first, but it's completely harmless. The bulkiness of this heatsink can discourage a novice setting up their own computer for their first time, but if there is a will, there's a way. Thermaltake's reputation is strong when it comes to heatsinks, and computer components in general. The heatsink has four copper bars, and the bulkiness of the design is for conducting the heat coming from the CPU effectively and also, at the same time, the surfaces dissipate the heat. Let's find out if this medicine will tame the fever.
