So far since i've gone to water i've got my A64 in Sig. up to 2406mhz 1.65vcore (stock 1800mhz 1.4vcore ) so far water has gotten me 100mhz more OC than my air setup and she's getting hot even with water (61C load), i need more and i believe it's my *little* black ice microII rad is holdin me back. Here is what im asking from you guys... What's the Advantages of Single-Pass rads vs. Double-Pass rads ? It seems Single-Pass from what i've read on DD actually cools better... So why get a Double-Pass ? Also this is probably pure opinion BUT what would you say is a good sized Rad for NB and CPU cooling (1 120mm, 2 120mm, 3 120mm)? I dont plan on OC'ing Video because it scares me, i've lost one 6800GT already and one man down is too many lol.
