Geeetech v4.0 noisy

I need a cover for the motherboard fan v4.0
The motherboard fan is very loud and always 100% working. Is there any way to decrease the rpm?
Thanks!

Hello

Mother board fan is connected to the FAN2.B output on the new mother board GT2560 V4

Try this gcode : M106 S127 P2 to decrease rpm to 50%

S127 for 50% of max fan speed (255)
P2 for the FAN2 output

I had the same problem. Finally I upsided down the mother board fan and put a cover to exit air flow by the right side and reduce the noise:
