ParadiseOC posted a review on the Cooljag JAC68YC Heatsink

There are still people out there who don't like all the flashy nonsense and want something traditional looking that will have good performance when overclocking. Some people would just like a direct replacement for the OEM. This is where Cooljag's JAC68YC comes in. It doesn't resemble a jet turbine, or a tower... just the stock AMD heatsink. They have taken the stock AMD heatsink and tweaked it a bit. Will a few tweaks grant this heatsink better cooling powers than the stock AMD? That's what we are here to find out.
