Fan Headers
There are seven 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 in BIOS. When using Thermal Management setting, please use all
3-pin fans or all 4-pin fans.

a variety of card sizes with increased functionality and spatial efficiency. The M.2 socket on the
motherboard supports PCI-E 3.0 x4 (32 Gb/s) SSD cards in the 2280 and 22110 form factors.
