[Suspend Issue] Fans stay on running during suspend on Gigabyte B850

I’m experiencing an issue where my desktop system's fans continue running even when the system is suspended and its not wake-up issue. This only occurs on Linux — suspend behaves correctly on Windows (fans stop).

I have confirmed that the system is using deep sleep (cat /sys/power/mem_sleep shows s2idle [deep], and I’ve set GRUB_CMDLINE_LINUX="quiet acpi_osi=\"!Windows 2015\" acpi_os_name=\"Microsoft Windows"\

I suspend using systemctl suspend. The system does suspend , but the fans continue spinning, suggesting either the ACPI isn't handling fan control correctly.

On Windows 11, suspend works perfectly — fans shut off and resume cleanly.

Motherboard: Gigabyte B850 Aorus wifi 6e Ice

i just installed arch linux to learn it please anyone help me

if you found the controls of fan(platform drivers, acpica, ...) then you able to hook that cmd to systemd suspend.target or whatever.
not very helpful sory.
