Hello,
I have a DELL Inspiron 5491 that turns on properly but the fan is not spinning at all.
On the motherboard fan socket (FAN1) I can read this:
- pin 1: 5V_FAN_VCC = 5V
- pin 2: GND ok
- pin 3: FAN1_TACH = 3.3V
- pin 4: FAN1_PWM = 0
I ordered a brand new fan but same problem ...
BIOS settings already reset.
What could possibly be wrong?
Are both fans dead?
