I know Bob, I bet I'll end up wishing I'd listened to you in the first place and gone with a heater core, it would have been cheaper I'm sure.

I've been somewhat influenced (rightly or wrongly) by some of the arguments I read around this forum about the design differences between 'PC radiators' and heatercores such as the coolant-air temp differential, flow rates etc. Time will tell... Thanks for the pointer about blowers as well. I've seen a few pics scattered around the net with radboxes using these. They look like quite a nice neat solution. I wonder how much noise they produce? Definitely going to go with your sealed radbox solution. Looks simpler than using shrouds.

HS, (name nothing to do with 'Fawlty towers' is it?) my main priority is reducing noise. Specifically that of the HSF and the annoying whine of the little 40mm fans on the NB and GPU. I'm hoping that the NB (875P) and GPU(9600pro) don't add too much heat to the loop, though I've been finding it difficult to find out any heat info at all for these. At the moment, with the irritating whining, its difficult to tell just how loud my hard drives and PSU (enermax EG465EX) are. I know I'd rather have a low pitched humming than a high pitch whining though.

With a sealed radbox, would one or two larger slower spinning fans (as suggested by Butcher), be quieter / more efficient?
If I go with DC fans / blower I can control the speed they run at, so can fine-tune the noise-temp tradeoff. Is this possible at all with AC fans?
