Rebuilding my loop in preparation for the 2700k I just bought.

I don't think I'm going to liquid cool my 560 Ti 448 Classified like I once thought... it takes a long time to uninstall/reinstall (MCW60+ramsinks), will hurt CPU temps, and doesn't reduce the fan noise overall (except during games/load). Higher clocks are tempting, but I feel like I'll instead just be upgrading cards so quickly that won't much matter... I'd still like some input on this just in case this takes me all night and I'm very wrong about all this.

So that leads into the real question: by removing the GPU from the loop, I've decided to take out my second, smaller radiator which is an old Black Ice Xtreme single 120mm. Less fan noise, and the triple I have should be enough for CPU-only. Then I started thinking... why not leave it in, but passive? Would the resistance be worse than the extra bit of radiation it provides? I have an MCP655 and Apogee XT.

If the answer is "leave it in", I next ask how terrible it would be to cover up one side with a large fan. There's already a 120x38 fan on it, and I might even just leave it for optional use if you guys don't think the lost exposure would be bad.

I suppose this creates another option. Leaving in the thick, dense BIX radiator, and putting a slow normal fan on it. This would be very low noise, but more restrictive than just the triple radiator, of course... more complication too.

Thanks, and hopefully I get some quick replies because I'm off to go clean the blocks and try to decide if I should reuse this [expensive to me] tubing...
