Computers require multiple voltage levels on the motherboard, typically including 1.5V, 5V, and 12V, due to the diverse power needs of various components. Most standard PCs utilize these multiple voltages, while some embedded systems may operate on a single voltage. Heat generation in processors is a common concern, attributed to the high density of electrical components and their operational characteristics. The CPU, being a critical component, generates significant heat, and while it is often referred to in discussions, it cannot be physically opened without damage. The term "lock based" in relation to processors refers to the design of the CPU pins, but further clarification on its implications is needed.
