Iv'e heard that the most expensive part of a water cooling system for a PC is often the water pump.
I would like to put forward the idea of using a relatively cheap computer fan (probably a delta as these are powerful). waterproof the electronic components with silicone and by cheap sealed bearings
for the fan then submerse the fan in the water in a duct and use as a pump. I don't believe that the fan would fail due to the extra load as they are brushless and the commutation is ontrolled by a hall effect sensor. This controll circuitry will probably get hotter due to the extra load but carefull application of silicone will allow this hall efect sensor to be cooled by the water without the leads being expsed to the water.
excuse my method of response as i am to dumb and too short of time to learn how to do it properly.
some fans are quite pwerful take the FFB1212EHE Delta

A quick look at the cooling products on offer at Crazy PC suggests a typical air fan has a power rating of around 1 watt, while their water pumps are rated between 9W and 23W. This suggests my intuitions are correct that a fan would be nowhere near powerful enough. |

[vlies] when an idea is called "Water cooling idea" you know you are asking the big boys to tear you up! Welcome to the bakery |

You might be able to get a TMD fan inside of a duct filled with liquid while the magnetic drive components remain outside the duct ... but then you would need some mucho power for it to rotate fast enough to see worthwhile results ... not too bad for being halfbaked. I don't think it would work, but a very noble first attempt ... |

And we haven't even entered the domain of compressible fluid dynamics yet. There are reasons why pumps don't look like fans. I don't see why water pumps would be pricy at all. |

The Moby Brick PC that was used in early variants of the UK's Challenger tank were sealed boxes that were filled with a liquid that conducted heat but not electricity and the case acted as a heat sink/radiator. |
