I downloaded ASIstudio
#1 when I plugged in the power and usb cable the fan turns on
#2 when I start the camera - in ASIstudio - the fan DOES NOT stop. I took a couple of images to make sure I had the camera on.
#3 the camera will go automatically to about 10C below ambient. If I haven't set a cooler temperature, it will hold that temperature. If I set the temperature lower, it will got to that lower temperature and hold.
