The TT GF4 hsf is made of cobber unlike most of the ones that come stock with the cards which are alu. It should dissipate heat a bit better and tests have shown it to do so.Originally posted by: LiqwudIce
The first one looks to me like the stock cooler with a couple of extra ramsinks. I have the second one and it's not meant for an overclocker, however it has been shown to give better results than a stock cooler if there is a fan on it, such as a side case fan. Otherwise, the second one is just meant as a quieter solution, not a cooler one.
