====== Centaur Cooling Fan Noise Mod ====== **From the Ten-Tec Reflector June 18, 2006** I added a 100 ohm 5 watt resistor in series with the fan motor. I also removed the cover grating bars that were in front of the fan to increase the amount of air flow. These 2 changes quieted my centaur down a lot. Carl Moreschi N4PY
