Hi to all!
I want a little help here.
Does anyone knows how many PWM fans can I connect to the CHA_FAN1 or CHA_FAN2 so I can control them through the bios?

Dows anyone knows how many AMPS can provide this two fan headers?

Thanks

The motherboard fan headers have a maximum of 1 amps unless stated otherwise.

Thanks for your replay. I am a little confused because in the manual say that the CPU_Fan header have 1 AMP but nothing for the other headers. So The other headers have 1 amps maximum as well?

Thanks!
I just got an answer from Asus Tech Support for that questions. The answer was that the M.2_FAN, CPU_FAN, CPU_OPT and CHA_FAN1 and CHA_FAN2 have output 2A!! So I am good to go! The last think I wish to ask is if I can connect 2 DC fans (3 pin) with 3 pin splitter to one one of the CHA_FAN header. Can I?
