The AB31513 1x500W audio amplifier board uses Sure Electronics' T-AMP technology, which features low distortion and low noise level. This amplifier board supports mono amplification using PBTL topology. The fan runs when the heat sink temperature reaches 45 degrees Celsius and stops when the temperature drops to 40 degrees Celsius.
Hence the audible noise and idle power loss brought by the fan may be omitted when the RMS output power is moderate.
