i have built a rather unique water cooling rig. i have a 2g tank sitting in my freezer with a beckett gold series model G535AG20 water pump submerged and a radio shake thermal probe watching the water temp. this pump is quite the performer as it needs to pump the water 25 ft. round trip with a height change of 3 ft. unfortunately it's giving off too much heat as i can't get my water temps below 4c. any suggestions as to how i might fix this would be appreciated.

pump too hot

are you saying it wont get below 4c with the computer off and no hoses running out of the freezer?? or that it will not go below 4c when running ,,,freezers really arent that efficient ,,they basically are air cooling and need alot of surface area to keep up ,,try running the water through 20 or so fett of copper tubbing in the freezer after the res/pump before it goes out ,,and insulate all lines outside the freezer and in the case

4c is the temp of the water in the resevior in the freezer with the pump running. the water flows through a radiator in the freezer, then 13ft through insulated tubes to my waterblock (testing phase so not attached to cpu) and than 13ft back to the tank. this pump puts out a lot of heat. the air temp of the freezer is -17c to -23c. i'd take the pump out of the res. and put it in-line but the pump needs to be submerged to dissipate the heat and keep itself cool. anyone know of an in-line pump that can handle the amount of pumping i need without being submerged?

Try increasing the diameter of the hose/piping you are using. Believe it or not, not all the heat build up is thru the pump, some of it is caused by friction of the water thru the piping. Plus an added bonus of increasing the diameter of the hose/piping is an increase of flow rates. Also, make sure the pump does not have to lift any of the liquid. Most pumps do not perform very well when they have what is called "negitive suction" The pump you are using will work just fine unsubmerged. If, however not submerging it bothers you, place it in a pail of water. Or better yet, attach a HSF combo on it.
