Yes i checked the fan. I tried another fan. With 12v from an adapter works the fan. But when i put it in psu then upon pressing power button the pc starts the psu fan just move for a split second and then beeps with red led on the back of psu. Then i have to press the reset button on psu so the beeping would stop but the fan wont work.
The original Globe RL4T B1352512MB-3M fan is a 3-wire fan and cannot be replaced with a 2-wire fan. The third wire (usually white or yellow jacketed wire) is the tach signal that the PSU uses to determine if the fan is spinning. The PSU's blinking red LED and short beeps tells you that it is a fan problem.
