wedan,
Customers may notice an increase or decrease in noise levels from the system depending on the surrounding room air temperature.
Air Temperature Sensor
The OptiPlex™ 755 system includes an air temperature sensor built into the control panel of the system. The sensor measures the temperature of the air pulled into the system and adjusts the system fans accordingly. The customer is not able to monitor the system temperature using this sensor; it is strictly a behind-the-scenes function.
Customers may notice an increase or decrease in noise levels from the system depending on the surrounding room air temperature.
The temperature sensor is located near the front fan on each of the four chassis. The locations are as follows: the air temperature sensor on the SFF chassis is the two-wire cable that runs across the bottom of the chassis and connects to the I/O panel.
