I personally am a big fan of ThermalTake…all of my heatsinks and whatnot are Tt branded, and I am quite happy ;).
I’ve seen some of the best are self made…for now I will stick with my Exos and maybe start upgrading parts for it (I’m already looking at a new radiator…something like the Black Ice Extreme II ??)
And if my system corrodes, Koolance will be dealing with it. They sold me the Exos, the water blocks, and the “Liquid Coolant” which prevents corrosion and all that other fun stuff.
Water Wetter weakens plastic supports in the pumps, stains the hoses permanently, and also causes leaks…found this out the hard way ;).
I found a lot of this at http://www.amdforums.com/ thanks to hburrows83…read a bit more of their forums and I was pretty pleased about their knowledge base! Of course, CDF still kicks ass and will always kick ass
