Has anyone thought about using an automotive electric waterpump in their PC? The flow rates are insane at 35 gpm, but I was thinking that you could reduce the amps going to the pump and make it flow at a much more reasonable rate. This would in turn reduce the noise and heat generated as well. They seem pretty high quality compared to the pumps used for fishtanks. At www.summitracing.com they have a Proform Electric Water pump that is blue or red anodized aluminum for $139.88.

Here is a pic of what it looks like.

It's listed at $149, but in the Summit magazine I just got, they are on sale for $139.88. This is a little more than the high end fishtank pumps.
 
Nice looking pump. Has two outlets tho, and I bet it's loud. Why not pick one up and tell us how it pans out? You can always put it on ebay if you don't want it.
 
I would say you could find one cheaper some place else. I would do a google search or something and see what you would find.
 
I was thinking that with those two outlets, one could go to the GPU and NB and the other to the CPU. That way you don't have to have the water flow go through a series from your hot CPU to your GPU and then to your NB.
 
My God man! That's 2100/gph! You cooling down a computer or puuting out fires:D ....................LOL. Better have some good hose clamps.
 
It's a cool idea, but in all actuality, completely pointless. In most 1/2" ID systems, the point of diminishing returns falls somewhere between 350-400GPH (10-12 Ft. Head) Anything more is a waste of pump power and money. Not to mention the wattage required to run the thing.

-EDIT- Not to mention, an automotive waterpump may not be as yeilding as a magnetic drive pump. This means that the head is possibly more than a typical WC system could handle.
 
Well if he lowers the power like he said he was thinking about it sounds good. So say it cut the flow in half that would be about 1050 gph.
Then if like someone said here he has the cpu and gpu (and anything else maybe) not flowing together than that would also reduce the flow to things some.
He could also reduce the flow other ways but it would build up the pressure also. And yes he would need hose clamps for that set up lol.

I though about this a while back. And I think even said something about it on this forum. But I ended up staying with air cooling so never tried it. If I ever decide to get into overclocking more and go water cooling I just might try this idea as it sounds to me like it would work great.

If he used something like a long under ground rad it would work extra good. That way the flow would go way down by all the piping and turns it had to make. But still at the end have a good flow. People who use things like that have found they need a good size pump to keep the flow good so this idea would fit right in.

I used to be a plumber and we used to use small pumps to pump water to solar panels. I have also thought about them for water cooling and they also would work really well. They would have better flow and could raise the water a lot more than most pumps used to it. We used them on 2 story houses many times to pump water to the roof with no problems. And you can get them that will run on 12V so could power them from a 4 pin connector.
