Only problem is fan noise

Got one of these on sale recently. I have used many BR1500LCD's at work and thought the only difference in this model would be the green features for power saving. Not so. My application was in a media center location and the fan on this model is designed to run even while on A/C power. The noise generated by the fan is unacceptable in this type of application. According to APC support "the Fan in the unit, will always Runs, this is not an issue. The BX1500G went through a design change in which it was decided to switch to a different fan and to keep the fan on all the time. This means the fan will run while the unit is plugged in, whether on or off. This is to help reduce heat at the internal components, increasing service/battery life." In my experience the fan ran when the load was around 250 watts or higher and once it kicked on it stayed on until the PC was shut down. If the load was lower than that threshold at boot the fan did not start but if it got higher during operation it kicked on and stayed on. It is loud and annoying when trying to watch movies or tv. APC agreed to RMA it for a BR1500LCD. According to APC support the fan on this model only runs when 1.Tthe ups is on battery, 2. The UPS is charging the battery. 3. The UPS has a load greater than 75%. 4. The internal temperature of the UPS has reached greater than 140 degrees F (60 degrees C). In my experience I have had these models at 500 watts and never heard the fan at all. I have never heard them during charging, battery usage or any other time. If you need a quiet ups stay away from the XS series (BX model numbers).
