Fan Header
There are two 4-pin fan headers on the motherboard. 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.
