Would I have problems with a Hydor L30 and a Maze 4 gpu block?

[Codeman05]

I'm switching over to phase change on the CPU, so instead of letting my watercooling parts go to waste, I'm going to WC my Radeon 9800pro.

I plan on running: L30 pump -> HC -> GPU -> L30
And there will probably be 3 90degree elbows in there so I can keep everything in the front of the case. Normally I wouldn't use elbows, but with 320gph and just a gpu block, I don't think its gonna effect much temp wise.


My question is, can the Maze 4 GPU block take 320GPH? I'm sure it can...looks pretty stought, but I'd like to be sure.

btw...I know the L30 is overkill for just a gpu, but I dont want to shell out 35-50 bucks for another pump when this one is running great

It'll work just fine. Also, you're not going to get 320GPH even if you just had a loop of tubing. That is a very optomistic rating measured with ZERO flow resistance (no barbs, no tubing, nothing). For water cooling, the important measurement is head pressure. To aquarium pumps, all w/c setups are flow restrictive so the GPH measurement isn't worth much.

I wouldn't worry much about the elbows, the maze4 GPU block (and MCW-50 also) don't require insanely high flow rates to work well. Obviously it would be better without them, but some cases (especially GPU cards) make routing difficult without tight turns. I would concentrate on keeping the inlet to the pump restriction (elbow) free as possible. Restricting the inlet WILL hurt flow and possibly cause the pump to be noisy due to cavitation in the pump (also a bad thing).

yea I realize 320 is optimistic, but I was thinking worst case for this particular senario ;)

Thanks for the info, I should be able to keep the inlet pretty unrestricted so this should work fairly well. I should have everything in Friday or Monday. I'll post something when everything is done

Yeah, sounds like it'll work fine. It would take a lot of pump to damage a waterblock - you'd have tubing exploding and flying off the fittings long before anything happened to the block.
