What is pc Cooler ?

A PC cooler is any device or system designed to remove excess heat generated by computer components to keep them within their safe and optimal operating temperature limits. Without proper cooling, components like the CPU (Central Processing Unit) and GPU (Graphics Processing Unit) can overheat, leading to performance issues (known as "thermal throttling") or even permanent damage.

There are several main types of PC coolers:

Air Coolers: These are the most common and generally consist of:

Heatsink: A metal (usually copper or aluminum) block with fins that directly contacts the hot component (like the CPU) and absorbs its heat.
Fan: A fan mounted on or near the heatsink blows air over the fins, dissipating the absorbed heat into the surrounding air and away from the component. Air coolers come in various sizes and designs, with larger ones generally offering better cooling performance but taking up more space.
Liquid Coolers (Water Cooling): These systems use a liquid (usually a water-based coolant) to transfer heat. They typically involve:

Water Block: A component placed on the CPU or GPU that absorbs heat into the liquid.
Pump: Circulates the liquid through the system.
Radiator: A series of fins where the heated liquid transfers its heat to the air, often with fans attached to help dissipate the heat.
Tubing: Connects all the components, allowing the liquid to flow. Liquid cooling can be either "All-in-One" (AIO) closed-loop systems, which are pre-assembled and easier to install, or custom open-loop systems, which offer greater customization and often superior performance but are more complex to set up. Liquid cooling generally provides better cooling performance than air cooling, especially for high-performance systems and overclocking, and can also be quieter.

Beyond the CPU and GPU, other components in a PC also generate heat, and cooling solutions are often in place for them too:

Case Fans: These are mounted in various positions within the PC case (front, back, top, side) to create airflow, drawing in cool air and expelling hot air from the system.
