Processor heatsinks are essential components in modern computer systems that help dissipate the heat generated by the CPU. These heatsinks come in different shapes and sizes and are made from various materials, including copper and aluminum. They work by transferring the heat from the processor to the surrounding air, which cools down the CPU and prevents it from overheating. Some of the most popular heatsink designs include tower-style heatsinks, low-profile heatsinks, and liquid cooling systems. Choosing the right heatsink for your computer system can help improve its performance and extend its lifespan.

Frequently Asked Questions (FAQs)
1. What is a processor heatsink?
A heatsink is a piece of metal that sits on top of a computer chip such as a CPU and draws power away from components by letting it rise through a set of fins. By themselves, heatsinks are passive; they have no moving parts.
2. Do processors come with heatsinks?
The short answer is yes, most CPUs come with a cooler. However, there are some exceptions. The best thing you can do is to check the specifications on the computer's website (if you are buying a PC) or contact the CPU manufacturer directly.
3. What do heatsinks do on a motherboard?
Heatsinks are designed to move heat away from a computer's central processing unit. A motherboard heatsink is typically made of aluminum alloys or of copper.
4. Are larger heatsinks better?
It's irrelevant how long it takes for the sink to heat up, as long it is giving the source's heat a place to go and an easy path to get there. A bigger-than-needed heat sink is fine, as long as the thermal impedance between the source and sink is low enough.
