VRM MOSFET Temperature and How to Regulate It

A heatsink helps to disperse heat off of the VRM MOSFET The VRM MOSFET inevitably releases an immense amount of heat when driving power-hungry chips. Since ice baths aren't an option, you'll need to take a realistic approach to regulate the temperature instead so that its efficiency and longevity aren't compromised.
