best pump to use in water cooling

[William]

what is the best ~500gph pump to use for water cooling. Preferably it would operate in the open and not work as a submersible but I am open to getting a submersible pump. Where is the best place to get them too. Not too worried about the price.

try www.thatpetplace.com (http://) they have a large selection, there all good(eheim, danner magdrive, ect). if it's going to outside the case make sure to get a pump with a good head rating.

I ordered mine from www.petwarehouse.com .
It's Mag-Drive(Danner) 500GPH pump (can be used for both in-line and submersible) and price is ~46 dollars plus ~6 dollars shipping and handling. After changing my pump from Eheim 1046(pathetic 80gph) to this 500GPH Mag-drive pump, my temperature went down 4 degrees. This is very solid pump. Just make sure you get the fittings for the pump. They have 1/2" fittings and you need 1/2" to 3/8" fittings if you have 3/8" hose.
