A few months back this message appeared while doing multiple approaches so I replaced the cooling fan. The message occasionally appears with the new cooling fan and when I tested it by activating the avionics in my hangar I heard the cooling begin to operate after approximately 10-15 minutes. Additionally, I bench tested the removed fan and it operated perfectly for over an hour. Any advice or recommendations would be helpful.
