to reduce the heat. its acts as a coolant
All CPU cooling fans will come with installation instruction. It's a bit challenging, but a novice certainly can do it.
One or more of the computer's cooling fans may have failed, there is restricted airflow in the case, the CPU is overclocked or the heat dissipation paste between the CPU and cooler fan has dried out.
If you mean CPU as Central Processing Unit, then theres one mounted onto the CPU. If you mean CPU for Computer, then theres at least two or three in the computer. Theres one on the central processing unit, one in the power supply box, and one on the computers case. There may be more added on other places of the computer's case.
It keeps the Cpu cool, any significant heat in the Cpu can cause damage.
One possible reason for a computer shutting down by itself is if the CPU were to overheat. I advise checking the cooling fans.
computer hardware
The fans usually connect to the motherboard, but they can connect directly to the power supply unit.
Motherboard, hard drive, CPU, GPU, cooling fans, optical drives, floppy drive and powersupply.

The function of the CPU (Central Processing Unit) is the heart of the computer. Everything the computer needs to do has to go through the CPU. The CPU tells the computer what to do, when to do it, and how to do it.
Viruses affect your computer's CPU by consuming both CPU time and resources. A virus is just like any other program: it needs dedication from the CPU to properly execute. This can cause the CPU to slow down significantly if your computer is infested with viruses, since the computer cannot respond to each and every process in a timely manner. There is also such thing as a "CPU virus". These viruses infect and damage the actual hardware of a computer. Since it is damaging the hardware of a computer rather than the software, the restoration afterwards can be pricey and there can be little to do to stop the virus from destroying your computer.
CPU stands for central processing unit. As the name implies, the CPU processes everything the computer does and handles everything that goes on in a computer. The CPU is often referred to as the brain of the computer since everything goes through the CPU first. The purpose of the CPU is to read machine language and do what it is told by it. The machine code are the directions on what the CPU should do, but the CPU is needed in order to read this code.
