Conducted a timed temperature drop test on the chiller.
The following are my results:
24.5C to 0C = 6 min 8 sec
24.5C to -10C = 8 min 25 sec
24.5C to -15C = 10 min 38 sec
Anything below -15 I start to question the accuracy of the Phobya G 1/4 Thread Inline Temperature Sensor due to how much the reading was jumping around.
-23C was the lowest recorded reading.
-10 at CPU @ 1.5v
