hi guys I ve been working on this card with weird symptoms and i can t spot a faulty componant .
The card powers on somtimes showing the bios screen , but somtimes it is not even detected the fan doesn t spin on both cases , i mesured the voltage on the 2 pin fan wires .
On one end it is reading 12v and on the other it gives also a voltage 10v wish is weird and it turned out that this is the only hint i ve got on what is wrong about this card
I found a schematic for a two wire fan for the gtx 750 wish is similar to mine
there s no gnd on the second pin , and the i tested the mosfet and the diode they seem to be fine .
I can t understand the proper functioning of this schematic can someone enlight me on the basic function of this circuit so i could first of all get the fan to spin .
thank you in advance
