Hi,

I'm cooling with a MAZE2 an Eheim 1048 which gives me a flowrate of 43gph. I have a leviathon heater core that is so oversized that it isn't even a factor. My CPU pushes about 112W of heat. Now my water res temp is 12C and my CPU temp is 29C. COme Summer, I'll have an unstable computer. Any possibility I could get the CPU core to within 7C of the water temp? Shouldn't I be seeing better temps than these? I'm positive that my WB is seated properly and I see a perfect imprint of my CPU when I remove it, but the WB always feels cold to the touch when I'm running full load. The waterblock does have a few minor scratches. My pump connects directly to the res and to the radiator.

These are the next steps I'm contemplating:

1. Upgrade to Eheim 1250.
2. Lap my block with 600 grit paper.
3. Try a different water block (Z4/sidewinder)
4. Upgrade to 1/2" from 3/8".

It seems like I'm not getting good heat transfer from my CPU to the water. Any suggestions about which of these three steps would improve cooling more. Is the base of the MAZE2 too thick?

Thanks!

Rob
