A6000 Can't enable fan contorl

I am training my model and the temperature is 85 c, so I want to increase the fan speed to cool down. When I run the following command, I get an error. I have already set coolbits to 12

~$ nvidia-settings --display 10: -a “[gpu:0]/GPUFanControlState=1” -a “[fan:0]/GPUTargetFanSpeed=60”

ERROR: Error resolving target specification ‘gpu:0’ (No targets match target specification), specified in
assignment ‘[gpu:0]/GPUFanControlState=1’.

how can i fix it?
