In your opinion, will this work?

Recently, a sad thing happened. My apartment burned down and I lost all 3 of my computers. (dual 366@550, Dell PIII laptop, Sun Blade workstation) Well, now I have to build a new, super tough system with the insurence money (of course). I have plans on the table for a Dual 1.4Ghz Athlon MP system based on the Tyan board. I went with water cooling because I would like to sleep at night with my computer on. I have purchased (2) swiftech water blocks, an Eheim 1250 pump, and (2) fairly large radiators. The problems I see deal with the difference in hose size amoung the components. I would like to optimize for the best flow.

(2)SwiftTech Blocks - 3/8 outside diameter
(2)Radiator - 3/8 inside diameter
Eheim pump - around 1/2 for both

My plan is to split at the pump to maximize flow there, take both of those feeds each to a radiator, then to the blocks, converting down near the block, then bring it back to the pump. Is this the best solution. Any advice would be helpful.. Thanks

Don't split by the pump, each split reduces flow. And try and not to use 90 degree elbows. Use a Y-spliter. I'd reduce right at the radiator. I'd either replace the fittings on the block or buy the 1/2 in fittings from swiftech. And I'd put the radiator after the blocks. Thay way the cpu will get the full force of the water.

Hummm. I know that spliting at the pump will maximize flow, the pump fitting is 1/2 and the two radiators I'm going to are 3/8 so a split like this..

Will surely maximize flow from the pump, it will act like a single 1/2 tube all the way around. This of course only works cause the pump fitting bigger then the two I'm spliting too. As for the bigger fittings on the block from swiftech.. I didn't know they made them, thanks, I'll go get em.

darn HTML.. that's suppose to be a BIG tube, getting split to 2 smaller tubes.... to maximize flow
