Has anyone looked into replacing the two fans (DA09225B12VH DC12V 1.05Amp) inside the EG4 6500EX-48 inverter to make it quiet? It seems, they are using 4-pin PWM type fans (see attached photo) and I could replace them with Noctua quiet fans but Noctua fans draw little power compared to the fans inside the inverter drawing 12 watts each (12V*1.05A). Does anyone have the data sheet for the DA09225B12VH fans?
