Monte Wilson of ASNSW water cooled his SBIG STL11000 by rigging an amazing set of gravity fed tubes from the water tank tower at the imagers house at Wiruna. He ran tubing under the ground through his camera and up to the tank, had to dig a trench and all....So extra cooling is deffinitely desirable given the lengths some will go to get it but not having to use water cooling in the first place and still having better cooling is..?..even better!
