温控散热2.0[Extruder Cooling TemperatureControl 2.0]

The cooling unit uses a 3010 fan, and 5V or 12V has little effect, 

The temperature control switch adopts a KSD9700 normally open type, with a selection of 45 degrees or 50 degrees (low temperature is preferred for non tight contact) 

Excluding the power supply, the total cost is less than 6 yuan

1. Power supply problem: The individual is not very familiar with the circuit and has no confidence in taking power directly from the device. If the external power supply is 5V fan can use the old USB power supply and charging line (the general red line is positive); If it is 12V fan can use DC power supply (general flower is positive) 

2. Fan buckle up and down card tenon length is different, short card tenon is on, long card tenon is next, fan buckle used interlock design in order to strengthen stability, If you need to remove the buckle please remove the fan, slightly on the buckle above the pressure can be taken out, violent demolition may lead to buckle fracture 

3. Why is the ventilation rather than hair, personal feel that the hair inside the spoiler is larger, but the hair effect should be better
