I think you mean to ask "what's the function of a heat-sink on a pc motherboard" in which case the function is to keep the cpu cool and prevent it from overheating.
plugged into motherboard
The CPU (Central Processing Unit) is either a AMD or Intel processor. If you are using a desktop you will be able to locate it on the motherboard. Its under the heat sink/fan on your motherboard. Carefully remove your heat sink and you will find your cpu.
The heat sink absorbs the heat from the processor and then the fan disperses the heat.
It helps conduct heat away from the object on which it is placed. Without the heat sink, a computer CPU would get too hot to function.

The three factors are : Using wires of specifications that match the power requirements of motherboard . Use the fan or heat sink properly. Do not use faulty devices with mother board.
I would have to say the CPU, the CPU is needed with any computer. If the CPU doesn't have a fan or heat sink it'll kill your computer, kinda like your brain
To sink the heat.
YOu can damage the motherboard
The processor (CPU) is on the motherboard inside your computer. It's easy to spot it's location because theirs a fan above it cooling the massive heat sink that's glued with silicon to it.
Processor, RAM, daughter cards, CMOS, Heat sink
The first step to getting to the CPU is to unplug the computer. Open the left side of the computer if it is a tower, or the top if it is a desktop. Attach an ESD(Electro-Static Discharge) strap to the pc case, then to yourself. Unplug the fan just next to the power supply from the motherboard. Remove the fan from the computer via clips. When you have removed the fan, examine the heat sink. The heat sink is the aluminum vented/slotted block that the fan was hiding. After you have examined and figured out how the heat sink is held in place, carefully remove it from the computer. Now you have exposed the CPU. The CPU may be held in by a small metal arm on the side of it or may have a square metal ring. You can gently lift the CPU out of the motherboard after you have released what is locking it in place. You can figure out how to remove these parts carefully and without incident if you look at them close enough.
