How to choose a CPU cooler?

Choosing the best CPU cooler isn’t rocket science, but there are some technical details that you need to know in order to make the best choice. There are many reasons why everyone who has a computer or decides to build one should use CPU coolers.

Computers that are ready-to- use usually come with built-in CPU coolers, but that doesn’t mean that it they are unbreakable. When looking to find computer parts that will help you build your dream computer, you must make sure that you know what you are investing in, so in case the cooler stops working all of a sudden, you know what the most suitable model for your needs is.

If you are one of those people who like to build their own computers, by choosing parts that satisfy your requirements, you should definitely know what to look for in the best CPU cooler.

You might wonder why we are emphasizing the importance of this spare part so much. In fact, it is one of the most important parts, as it ensures the right temperature of the CPU and helps you avoid overheating and damage.

You are interested in buying a CPU cooler that is high quality and fulfils your requirements, but you don’t know what the qualities of a good one are? Here are a few things that you should be looking for when looking for such a product:

  • The materials - an aluminum cooler will never be as good as a copper one, for instance
  • The size – not all sizes are right for all computers. Also, larger coolers perform better than the small ones
  • The compatibility - some computers require special cooling fans, so you should always check the model compatibility
  • The heat sink – some coolers come with built-in heat sinks and some don’t
  • Overclocking – if you want to manually adjust the CPU’s clock speed, you need a larger fan with better cooling abilities
  • Airflow rating

In order to help you choose the best CPU cooler for your needs, we have reviewed some of the best-selling products on the market, by highlighting both their pros and their cons. Take a look at the products below and choose the one that is best for your needs.

Looking at the product’s specifications should be a priority. The price is also important, as you don’t need to pay more than necessary for an average product, but it isn’t the most important decision factor of all. Also, pay attention to the warranty that covers the product in case of damage or malfunction and choose a product that is reliable and durable.
