I picked up a Vantec CCK-6040H and am really unhappy with the quality of the Cooling. My xp2000+ would only go up to 143 mhz and under load was running ~52c. I am getting a Hedgehog type W with 2 fans on it to try out. We'll see how that goes, hopefully better. also- do you think P/S could effect stability/overclocking very much? mine is an enermax 330w its pretty nice, I think... it has dual fans and all... any ideas why I can't get my board above 143 stable? (besides heat)
