I have a 1140 GPH pump, The Lifeguard Quiet One. I get 3 gallons per minute at the return line, remember, my radiators(24 linear feet of 3/4" ID)has NO restrictions whatsoever, so its like running through plain tubing, so a smaller pump could run it and was till I upgraded the Mag 5 pump only cause I had a leak in the intake. Pump is only 87 watts(thats .73 Amps

), not bad for a 1140 GPH pump huh?
Temps are really stable, the water stays at about 3C above ambient and the CPU core stays at 3C above water temp, here is a pict:
