External Fan Controller W Thermal Sensor

The system uses a temperature sensor to control four fans that are driven by an arduino controller.

External fan controller w thermal sensor.

Great to control power to fans in your home heater or even your computer case. The project is built using lm358 op amp and lm35 temperature sensor. For more video s please visit my channel. Complete kit includes thermal controller mounting screws plastic stencil instruction manual and 100 125v ac wall adapter.

The remote sensor is a diode connected transistor typically a low cost easily mounted 2n3906 pnp type replacing conventional thermistors or thermocouples. In rare cases fan speed is regular and touching the sensor you hear the fan speed changing with the touch non touch of my fingers. Includes a 6 foot precision thermal probe that is water resistant. Operating temperature can be set between 32 to 140 degrees fahrenheit.

General description the max1669 fan controller includes a precise digital thermometer that reports the temperature of a remote sensor. Thermal sensor will turn the connected fans on at 87 f 30 c and leave them running until the temperature drops below 80 f 27 c external probe 450mm 18 inch in length so that you can monitor the temperature away from the controller. From bios too i can see that there is no temperature value for ambient temperature 0 that confirms the problem is in ambient temperature area. The arduino throttles the fans using pid logic and drives them through pwm.

Computer case 5 25 bay fan control. 3 channel fan control indicate. Fan knobs to control fan speed install. The max1669 fan controller includes a precise digital thermometer that reports the temperature of a remote sensor.

Coolerguys thermal fan controller. Temperature controlled on off switch. Fan speed controller fan speed control. Project requires 12v dc supply and can drive 12v fan.

The 3 pin adapter will fit most motherboards just have to know which way it goes on not designed for them though speed sensor will not work. The temperature and fan speed are reported through a 8 digit 7 segment display fitted on a rack mounted aluminium bar. Led display fan power. 5 25 drive bay material.

The remote sensor is a diode connected transis tor typically a low cost easily mounted 2n3906 pnp type replacing conventional thermistors or thermocou ples. About the best air cooling u can get. Computer 5 25 front panel bay 3 channel automatic temperature cpu case fan speed controller w hdd pc temp sensor led display. On the back side are two usb fan ports one power port and one thermal probe port.

Today we will make a circuit which can control the fan speed by sensing temperature. Loud sounds like a jet engine at full throttle. Um it screams airflow i had two on my case disabled the temp sensor so i could control the throttle good if u have a external fan controller cons.
