Pump drive capability

[porina]

Just wondering... how long a length of hose could a typical watercooling grade pump drive? I know it'll depend on many things like what else is in the loop, but assume for now, CPU block, GPU block, say a 360 radiator (maybe more), I'm thinking of a stupid cooling idea which would potentially need 20-30m in total. Think in the old LTT house room watercooling project he used a pond pump, which is not out of the question...

well, a pump needs basically no power to push liquid horizontally, tough pushing liquid vertically is pretty difficult. what kind of tubing setup would you be looking at?

Early planning stages... not thought it through yet. There will not be a significant height change, but even horizontally there will be a load due to the momentum/friction of water.

 

Idea is to have an external (to house) cooling solution (possibly open loop), while having PC inside. My other hobby is fishkeeping so I might or might not have something I can reuse there, if i can find the right adapters to go between them. Another option might be PC loop to heat exchanger, exchanger to external loop. Potentially more work.

 

Even with pond pumps, I'm a bit concerned as they're generally optimised for high flow and might not like restrictions in PC watercooling setup.

Most pumps list the specs on what they can do. Regardless you’ll need more than one for some out of room solution.

Take a look at Martin's Flow Rate Estimator: http://martinsliquidlab.petrastech.com/MartinsFlowRateEstimator.html

Download the excel file. He has done some research on the subject and come up with a table calculator that takes in the account the characteristics of the pumps and various blocks, fittings, hoses etc. It's a bit old and does not include the latest blocks, but it's fun to play with to get some rough ideas.
