I havn't heard of "PWN"...but I have Heard of "PWM" Temperature is that what you meant???

"PWM" is a circuit on mainboards to convert the voltage level from power supply unit to provide specific voltage to components (ex. Provide CPU with core voltage). We know that CPU could be the hottest component inside a PC system, and we always care about the heat dissipation of it. Actually, the PWM circuit is quite hot too; especially when CPU is at full loading, large current passes through the PWM circuit and was converted to necessary CPU core voltage. Some ABIT boards show "PWM temperature" on BIOS setup page and Windows hardware monitoring tool. This provides users possible hottest temperature inside the PC chassis, and check whether the air conditioning inside the chassis needs to be enhanced or not. When CPU works heavily, the CPU temperature could be around 60 degree C; nevertheless, the PWM temperature may achieve 70 degree C or even higher; depends on the design of thermal convection. The safety limit of the PWM temperature is about 120 degree C, however, we strongly recommend improving the air flow and heat dissipation inside the PC chassis once it rises to 100 degree C.
