Fan Headers
There are eight fan headers on the motherboard. These are 4-pin fan headers; pins 1-3
are backward compatible with traditional 3-pin fans. The onboard fan speeds are controlled
by Thermal Management (via Hardware Monitoring) in the BIOS. When using Thermal
Management setting, please use all 3-pin fans or all 4-pin fans.
