What is the coolist running water pumps.Not inline,in sump

[danny zubot]

I can't say exactly which pumps are coolest, but the lower the wattage is for a pump the lower the heat produced.

I've always liked the Aqua Medic Ocean Runner pumps. Don't think they add much heat but I can't say for sure.
