AC Infinity Controller 1 Preset Thermal Trigger

Control your USB fans using the Controller 1 Preset Thermal Trigger from AC Infinity. Powered by USB, you can use a separately purchased wall adapter or a USB port on your PC. Connect up to six fans totaling 10W, then control their speed based on the ambient temperature of your system measured by the Controller 1's 6-foot waterproof temperature probe. The controller features four pre-set temperature triggers at 84, 88, 92, and 96°F as well as on and off mode.
