On the MS-7E61 (customer ID 0x20d), the CPU and PUMP_SYS fan headers
are on channels 0 and 1, the system fan headers on channels 12-15
(pwm13..16), and the EZ Conn header on channel 3. The board has no
other fan headers.

I have no board with another customer ID, but the vendor's Windows
software lists the system fan headers of the MS-7D75 on channels 2-7
and those of the MS-7D76 on channels 2-4, with the CPU and PUMP_SYS
headers on channels 0 and 1.
