DC 12v 3a 4pin PWM PC CPU Fan Temperature Control Thermostat Speed Controller

4pin or 2-pin PWM Fan Temperature Thermostat Speed Controller Includes temperature probe • Ideal for Peltier Coolers & LED heatsinks We primarily sell these for Peltier cooler chip applications; this is also perfect for DIY or repair of LED or laser heatsinks. Automagically control 4-pin CPU fan speed with this nifty chip. Use the included temperature probe to program fan speed based on your heatsink temperature, or use in manual mode to toggle between speeds. Perfect for DIY or repair of LED heatsinks and Peltier cooler chip heatsink fans. Reduce fan speed when full speed is not necessary to eliminate noise and maximize fan life. Operating voltage: DC12V can work in the range of 8-18V. Current consumption: no more than 20mA Fan interface: 2510-4P missing a bend (computer 4P fan dedicated interface) Fan current: interface can withstand 3A, if you need to control the larger current fan, bypass power to fan PWM output range: 10% -100 Operating temperature: -20 ℃ to 60 ℃ Temper
