Looking for like res to rad to cpu..... that format for the best temos in a dual radiator water cooling loop.
temps not temos :)
Res ---> Pump ---> Rad ---> CPU ---> GPU ---> Res. If you have a known to run hot pump, putting it after the rad helps extend the life of the pump but increases temps on the cpu.
I will probably get the mpc655 pump from swiftech if you think that that is known to run hot.
Does not matter, water is moving around the loop so quick that it doesn't matter. You may see temp differences of literally 1 or 2 degrees.
As long as the pump is below the res, it will make filling the loop easy.
