w.rpi5.fan.rpm	RD uint	—	RP1 PWM1 offset 0x3C (CHAN2_PHASE);
firmware-preloaded static value — not live fan RPM

However my basic tests show:

# sysctl hw.rpi5
hw.rpi5.fan.rpm: 9661
hw.rpi5.fan.current_state: 1
hw.rpi5.fan.cpu_temp: 46300
hw.rpi5.fan.speed3: 255
hw.rpi5.fan.speed2: 255
hw.rpi5.fan.speed1: 255
hw.rpi5.fan.speed0: 255
hw.rpi5.fan.temp3_hyst: 5000
hw.rpi5.fan.temp2_hyst: 5000
hw.rpi5.fan.temp1_hyst: 5000
hw.rpi5.fan.temp0_hyst: 5000
hw.rpi5.fan.temp3: 75000
hw.rpi5.fan.temp2: 67500
hw.rpi5.fan.temp1: 60000
hw.rpi5.fan.temp0: 0

vs.

# sysctl hw.rpi5
hw.rpi5.fan.rpm: 0
hw.rpi5.fan.current_state: 0
hw.rpi5.fan.cpu_temp: 47400
hw.rpi5.fan.speed3: 255
hw.rpi5.fan.speed2: 255
hw.rpi5.fan.speed1: 255
hw.rpi5.fan.speed0: 0
hw.rpi5.fan.temp3_hyst: 5000
hw.rpi5.fan.temp2_hyst: 5000
hw.rpi5.fan.temp1_hyst: 5000
hw.rpi5.fan.temp0_hyst: 5000
hw.rpi5.fan.temp3: 75000
hw.rpi5.fan.temp2: 67500
hw.rpi5.fan.temp1: 60000
hw.rpi5.fan.temp0: 50000

vs. even a spin up still in progress, not yet
having reached its final speed range:

# sysctl hw.rpi5
hw.rpi5.fan.rpm: 6380
hw.rpi5.fan.current_state: 1
hw.rpi5.fan.cpu_temp: 50150
hw.rpi5.fan.speed3: 255
hw.rpi5.fan.speed2: 255
hw.rpi5.fan.speed1: 255
hw.rpi5.fan.speed0: 0
hw.rpi5.fan.temp3_hyst: 5000
hw.rpi5.fan.temp2_hyst: 5000
hw.rpi5.fan.temp1_hyst: 5000
hw.rpi5.fan.temp0_hyst: 5000
hw.rpi5.fan.temp3: 75000
hw.rpi5.fan.temp2: 67500
hw.rpi5.fan.temp1: 60000
hw.rpi5.fan.temp0: 49601


Looks  to be working to me.
