This product is from a series that already appeared on guru3d. The last two chassis fan headers are located in the bottom-left part of the motherboard, just below the last (bottom) PCIe slot. Two chassis fan headers are located close to the SATA connector. Two fan connectors are located close to the top right corner of the motherboard. There are two headers for the CPU fan + opt, but they are not placed like usually above the RAM slots, on the top-right side, but near the bottom of the socket area (and it’s not a good idea, especially considering the fan cable management). 6 x Chassis/Water Pump Fan Connectors (4-pin) (Smart Fan Speed Control).1 x CPU/Water Pump Fan Connector (4-pin) (Smart Fan Speed Control).Fan control on the Asrock Z690 Taichi can be accessed in the BIOS or ASRock A-Tuning in Windows, allowing users to customize the fan curve profiles for each of the board’s eight 4-pin headers.

The fan RPM range depends on what fan model you use.
