Ecat: even if i bring the water temps down to lets say 25C at load, it will only give me 4C cooler cpu, at most.. right?

Jah: tjena, the fusion block looks very interesting..

to all: i dont think the rad/fan setup is my problem here, and not the pumping power either.. running my Ultra Kaze at 2000RPM only gives me 1C improvement from running 5V... and modding the pump to 18W didnt make a difference at all..

but i may test modding the block a little.. there is som sot of "accelerator plate".. just a tiny plate with small holes in it.. i want to replace this with a piece of tubing with a narrow hole.. making extremely pressured water hit hte center of the block.
