Hey

What would be a good GPH amount for a pump??? stupid short question hoping for a smart answer.. the tank is big like BIG its an old ari compressor tank with tubing for the water to follow sotof a makeshift water radiator. Then again a car radiator wouldent be that bad of an idea.

Quick to the junkyard.....

Actually, right now theInnovatek HPPS 12v Pump(eheim mod) is really hard to beat if you have the space...and it is 12V DC, so it's quiet! A Hydor L30 is another great pump that's floating around out there. I generally didn't like the Eheim's until they got this 12V unit. They were just overpriced IMO.

If space is a concern, the little Danger Den DD12V-D4 pump is a great pump as well.

I'd look at the "rise hight" or "bars" as a good figure to compare pumps as well. If you decide to add more than CPU cooling, then pressure supply will become a large issue along with your choice of tubing diameter. And also take into account that the mixture of glycole and the likes will lower the rated performance. But basically, 160-200 GPH* is a good figure.
*Rated. As per the article below, real life rating is closer to 50.
