knipex:
1) I don't watercool parts that don't benefit from such; no hdd blocks or nb cooling for me. HDDs are cooled by a Panaflo L1A blowing on them and NB is cooled by a 50mm copper hs and very quiet (can't hear it even with ear to mobo) 5V 50mm fan. Perhaps in some cases NB water cooling might help; not for any system I have used.

2) For optimum results, NEVER undervolt or PWM fans. Doing so is a poor noise/airflow tradeoff. Find the noise level or performance level that is acceptable for your application and then use that as spec for your fan. I guarantee you that you can get more airflow at the same noise level by doing so than by undervolting or PWMing a more powerful fan.

3) Without testing the radiator and block, I can't really say too much more. Does the NexXxos Hp Pro have the thinner base (2mm)? If so I will go out on a limb and say it should have a fairly pronounced improvement with increased flow rates and if you can get the final system flow rate in the 3-4LPM range you should be doing a lot better than you are currently (maybe 1LPM max?). Even their thicker bp block should do a good bit better up in the 3-4LPM range. You could get to that flow rate with a swap from that multipass aquacomputer radiator to something like a Black Ice Pro 2 and a switch from 6mm id hose to 10mm (not much worse to route). Pump change may or may not be required.

Why do you think wizd (and alphacool) are bundling a BI Extreme2 style radiator, a higher pressure pump, and larger ID tubing with those NeXXos blocks? Pretty much the exact suggestions I would make to improve performance in your loop? It's not because their target market loves the American way of doing things for sure.

Greenman: There is no evidence that the MCW6000 is a better block than the AlphaCool.
