presents CPU fan error. I made welding the components near the connector (CHA_FAN). I no found the schematic diagram of the motherboard on the Internet, would help if could locate the scheme to
download.

The error only appears when it is enabled in the BIOS setup (CPU Q-FAN CONTROL)

Have you tried to reprogram the bios?

does this mistake is providing is why I am putting in CHA-FAN? I put the cooler on the CPU-FAN and did not present the same mistake.
