My Mac Pro 2019 exhaust blower fan does not operate anymore.. It started as noticing that the front system fans (the 3 fan stack) were running more often than usual. In Macs Fan Control, the RPM then started reading 0 RPM on the Exhaust fan and I cannot control the speed through Macs Fan Control. Then recently (after the service I will mention), the blower fan makes some bad grinding noises on boot, only to turn off and stay off.[br]

I had this machine in Apple Green Hills Nashville for service, where they said they replaced the blower assembly with a new one, but the fan still did not spin. They wanted to do more work on it, but it would be $1300 and more time, which I declined.[br]

I'm posting this simply because I have yet to see anyone with this same issue on the internet. I have ordered a used blower assembly from eBay to see if I can get a different result than my local Apple techs.[br]

I'm currently running Monterey 12.7.5 and will probably be upgrading the computer if replacing the assembly does not fix the issue. I'm suspecting a firmware
