Less power usage leads to lower thermal emission, allowing the CPU to stay cooler without intensive cooling. Benefits of Enabling "Quiet and Cool" Operation
The "Quiet" in the name wasn't just marketing. Before this, fan controllers were often voltage-based—if the PC was hot, fans ran at 100%. Cool’n’Quiet allowed the motherboard to interface directly with the CPU’s thermal diode. amd quiet and cool
