OK it's OFFICIAL now!
I accidentally left the pump running all night, which not only limited the cooling ability of the chiller by a few degrees, it also caused a bunch of unnecessary condensation. So I broke it down and made sure nothing was wet before I started up.
The chiller cooled down another 3-4 C while I was working on the block. The block is 3-4 F right now @ 4.5GHz/1.5v......which is way sub-zero in Celsius.
EDIT: all zeros picture added
Goal reached.
Sorry about the picture size, I think on a larger monitor than I have you could easily read the zeros.
