Hello. We recently purchased a 2010 MacPro over the internet and have been running tests to make sure its in working condition. Apple Hardware Test came back with error “4MOT/1/40000003: EXHAUST-704” and we cannot find any information regarding what specifically the problem is. The computer has two GPUs, a Radeon RX 580 and Radeon 5770, it’s a 5,1 and has 2x SSDs and 1x Traditional 7200rpm platter/rotational drive. Any help deciphering this error message would be appreciated. AHT (Hardware Test) Error 4MOT/1/40000003: EXHAUST-704?
