Sorry D1337, i tend to spell things how they sound. Sound it out, its a j not a g...
Anyway. In all the reviews i've seen, the Fusion cpu block out performs the apogee GTX even if the apogee has a "bow".
Oh, i should also mention that reading the description from the site your buying from is much better than the manufactures site (in most cases). The blocks come with 2 sets barbs so i should be fine there.
I guess i also have to get some thermal grease for the new blocks. Is there a specific grease better suited to WC systems? I'm fairly sertin that Arctic Silver is one of the best brands out there. I just dont know which compound is best. There have Polysynthetic Silver, Silver, Ceramique, and Alumina. Which is best? They cost within a few bucks of each other, i just want the best.
