I'm looking for a small, 12v pump to water-cool a rig my dad's building. Now before you all go off saying I need an Eheim 1250, we're talking much lower powered here. I'm using a 1046 in my own system and even that's over-powered. Something better than 25gph or 0.3l/s would be ideal.

I saw some mentions of 12v pumps made by Rio which sounded hopeful so if anyone knows of a UK reseller, please reply ASAP :)
I use a 12v bilge pump. At 12v it runs 500GPH and at 7v it runs I am sure around 275GPH. It will run at any voltage level you give it pretty much. At 7v it is silent. Mine is a v500. They are $11 here.


I have been running mine at 7v for about a month now. Many say they will break down early but I feel I have proven them wrong, just as many said my fridge would break down early too.
