Virtual-Hideout posted a review on the Thermalright TRUE Copper Heatsink

Well then, when it comes down to it, this TRUE is a bit of a paradox. It's a very heavy beast that performs to... some degree of fantastic, though to be honest, it really could be better. There are absolutely no qualms with aesthetics, design, or installation. Even the packaging is up to the par set. But honestly? What it comes down to are the materials themselves. Back when, the utilization of copper was in place due to the inability of the heatsinks to dissipate the heat, due to a low amount of surface area. The other issue in the pipe, though, is the fact that this heatpipe uses the same six heatpipes as every other TRUE; which means that unless it can dissipate heat any faster, the additional heat capacity won't do much all of good. It's all a shame, but I do rather love this sink
