What is thermal protection and is it on my D850GB?
The Intel Desktop Board D850GB has three temperature controlled areas that are monitored and are considered thermally protected. The ambient temperature of the D850GB Desktop Board within a system is thermally monitored by two separate temperature sensors at different locations on the board, which in turn control the voltage to FAN1 (located at J10A2) and FAN2 (located at J7M2). The D850GB BIOS set’s up the temperature sensing circuitry at system start up, following this initialization the sensing circuitry does not make use of system calls nor CPU bandwidth. The temperature sensing circuit is closed loop and controls turning on the fan if additional cooling is required and controls the fan speed of FAN1 or FAN2 as needed. Additional thermal protection is provided by the monitoring of the Pentium 4 processor by way of its internal temperature sensing diode. The processor speed is then increased or decreased based on the internal temperature of the processor. If the processors’ internal
