Our first Gfx phace-change cooling - Page 2

23rd July 2005, 09:23

I've worked on the system until 4.00 AM this morning, about the best I can get is -41.6°C evap temp with 50W load and -46°C unloaded, this with completely no insulation.

I have to the put it on the 9700 Pro though for further tweaking, I beleive the cap tube is a little too short for the small load of the peltier.

Pics will folow.

First of all, just before I left Jort's place, we noticed there was a small leak in the suction line.
Because I had no oxygen bottles left, I had to repair with a little butane/propane torch

Some soap testing after the leak was repaired:

Triple evac, vacuuming the low side on pic:

Another evac pic:

Charged and frosty, using a 50W as dummy load:

Frosty suction line:

Evap temp with 50W load, not insulated:

Evap temp unloaded, not insulated:
