How to connect the line of dc cooling fan?

Release time:

2021-10-18

The DC cooling fan has many power plugs. It is necessary to understand the effects of these and make reasonable design and connection before these effects can be fully applied. Today Xiaobian and everyone introduced the theme is: "DC cooling fan of these colorful line is how to connect?" Detailed information as shown below, temperature signal connection. Temperature signal in general to take the thermistor as a temperature sensor to do a good temperature sampling. Take the cooling fan as an example, the temperature change forms the resistance change of the thermistor, so the input signal has no polarity.

Just place the thermistor between the CPU and the heat sink, then unplug the jumper of the light yellow power cord on the heat dissipation fan, plug the light yellow power cord of the DC heat dissipation fan, and connect the temperature measurement power cord.

2. Connection of power line of governor. The manual governor is actually a variable resistor. When the resistance is adjusted to a lower value (or short-circuited with a jumper), the speed of the cooling fan is lower. When the resistance is larger (or the jumper is removed), the cooling fan works at full speed. There are two governors in the cooling fan random accessories, and one of them can be selected according to the situation.

The DC cooling fan can be assembled not only at the position of the 3.5 floppy drive on the front panel of the main chassis, but also at the slot position behind the main machine. Then connect the power plug to the red wire socket of the DC cooling fan.
