A friend and I both have observed the following quirk with the fan speed control on the QSI(683)
Irrespective of the fan speed setting, the fan always turns on fully with TEC, even when the temperature is reached. We found a work-around but am not certain if it is the driver, or SGP:
-connect the camera
-run with the cooler on
-disconnect camera but do not turn off the cooler
-change the camera fan setting to quiet
The quiet mode works now… but this process needs to be repeated each time you start up SGP.
