see diagram below:

I am going for silence. That means a 7v papst fan on my rad but i have found that doing this means my WC setup cannot sufficiently cool the cpu and gpu. So my answer to that was to fit 2 extra black ice rads and I also intend changing the original Maxexpert rad for a heater core. That combination will cool the cpu and gpu fine with all fans at 5v (x1 120mm and x2 80mm).

Problem is i have to get rid of the hard drive noise and enclose all three drives and wrap them in sound absorption material. The aqua drive units are the best i have seen and are supposed to make a drive completely silent (see: http://www.wizarddesigns.co.uk/hddcoolers.htm). So thats where the idea for a completely separate second WC system comes in.

For this I am quite settled on the airplex rad 'cos ive heard good things baout it, its pretty cheap and look fantastic (see http://www.wizarddesigns.co.uk/radiators.htm). Only problem is i can only mount it in the roof of the Lain Li 75 and doing this i'm unsure as to how to install its x2 120mm fans and whether they will get the rad cool enough.

If they are pushing air into the case then not only are they pushing in hotter air (from between the top of the case and my desk) but also there will be an inbalance with 5 slow fans intaking and only 1 exhaust (the psu will be fanless). Im not really sure of the consequences of this but i remember reading somewhere that it was better to have more exhaust than intake.

Thing is if the airplex fans are sucking air out of the case (one owner of a similar setup i spoke to said this works for him) then surely they are relying on the case air to be pretty cool ? I guess if i WC the NB and put direct that air from teh heatercore over the Moboard mosfets then theres no reason why the air won't be cool (but the fanless PSU is a worry here). Looking at the diagram maybe i should shift the airplex rad all teh way to the right and then put a wall between it and the psu. That way no heat from the psu will get near the rad

The other thing that worries me is the placement of the two Eheim pumps, the only way i can have 2 of them in there is for them both to be on the floor as per the diagram. Trouble is the 2nd system, the pump will have to shunt water all teh way up to teh height of the case ... maybe i should opt for a 1250.

Would appreciate anyones comments and alternative ideas ? I can really see anyway of getting another system in there and i dont want to run one huge system with a large pump cooling everything because that will only sacrifice my cpu and gpu temps.

(note that green areas are air proposed ducting tubes and also teh GPU could also be cooled by the 1st WC system and maybe the NB watercooled as well)
