It is suspected that the 4PIN power supply of the graphics card is broken, and the fan not rotate. Only through this line, can be transferred to the 4PIN pin of the motherboards, pluggeds in to get power, and the PWM temperature control function can be realized! copper wire, better conductivity and lower calorific value!
