GT2560 A+ FAN Voltage Problem! (solved)

[core2k]

Hey,

the pins on my gt2560 a+ board for the fans only deliver 4 volts instead of 12 volts. Reconized it because fans are blowing too slow. Maybe someone could help. Running the board with a 24volt power supply. Rest ist working without issues.

Thx

Edit:

Found the problem. It seems the internal stepdown converter has given up! After using a jumper to set the fan voltage to 24 volts its working. Had to change all fans to 24 volt ones. This problem happens after less then 20 hours of printing! For me this is not very confidence-inspiring.

Lets see how long the rest will do his work...
