PGXL Fan revs to maximum 1 second every 2minutes

My PGXL Fan revs to maximum for 1 second every 2minutes for most of the time while Amp is in Standby and Fan set to Standard Mode

Sometimes it less than 2minutes to cycle to get these 1 sec max rpm of the fan to occur

Is the temp too hot in Standby causing the fan to cycle on and off like this a lot

Sometimes it’s less than 2 minutes and fan spins fast but do not see any change in Standby Temperature

is there a bug in PGXL firmware 3.5.23 or is the PGXL at a critical crossover point in temperature at 36.7/39.1C inside the PGXL

Will try to get external fan to see if this behavior goes away !

Anyone else seeing this behavior ?
