What to look for in a good block

I have been experimenting building my own water blocks for the past 3 months. I am using a dual 120 heater core with a mag 7 pump.

I realize that there are alot of variables that come into play. But I just want to know when I am getting close to the best design I can build myself.

Right now my system is running with a block that has a 1/4' baseplate with 1/8' brass pins pressed in, in a chekered pattern.

The room it is running in is roughly 20 to 26 degrees c

Currently it is reading 37 at idle and 40 at full load for 3 hours.

I am just wondering how close to room temp I should expect. Thanks

Do you have a pic or a diagram of your blocks?
