UPDATE: I did a major overhaul tonight. I put the pump, and the feed line below the top of my reservoir, so the system is now gravity fed with no place for air to get trapped.
I'd say I have gained quite a bit. Right now the BIOS says the cpu is @ 5 Celcius and the reservoir is only @ -15 Celcius. Until now I have had to have the reservoir @ -32 Celcius to even see 5c on the cpu according to the BIOS. When I had the reservoir @ -45 Celcius this morning I actually saw 0 and N/A for the cpu.
Anyways I am expecting it to get much colder. And I'll post pictures tomorrow after I clean up the mess. Looks like a bomb-blast site when I get done doing a project.
