They say we must always be as cool as a cucumber. But, did you know that this doesn’t just apply to us, humans? CPUs must be just as cool as well. Otherwise, they will overheat and get destructive. The good news here, though, is that CPUs already come with a cooler, and this one works fine if you are going to use it without modifying your CPU. If not, you will need a CPU cooler.

If you are into gaming and high-end work (such as rendering videos for longer than 5-6 minutes continuously) that requires a lot of power, the CPU will start overclocking. For this, you need a cooler that can match the temperatures and cool your CPU down. Some computers are already overclockable, while others can be modified. In the first case, the CPU may or may not have a cooler in the box. In the second case, the cooler that comes in the box may not be enough. Thus, you will need an aftermarket cooler to meet your gaming requirements. 

Let’s get into the specifics now. If you have an Intel CPU, check which model you have. An i7 will definitely need a CPU cooler, but an i5 will work with the cooler you already have. Of course, this again depends on the amount of work and the kind of work you wish to do with your computer. An i3 would not need an aftermarket cooler at all. Those who love AMD computers will not have to worry about buying a new cooler unless they are planning to overclock it like crazy! 

How to buy a CPU cooler?

Now that you know whether or not you should buy a CPU cooler, we shall dig deeper and help you choose the right CPU cooler.

  • Find out how much heat your CPU generates. This will help you decide what capacity your cooler should have. The CPU’s box or manual should have this information. You can also look it up online.
  • Decide what size you need. A large cooler will have more capacity and efficiency because it has a large heatsink. Large fans are also quiet. The math is quite simple in this case. For more wattage (70 and up), buy a large fan. For less wattage (40 to 70), get a small one.
  • Check the compatibility. You will need to know your motherboard’s layout and sockets to understand this. If you buy a cooler that’s not compatible, you will risk delaying the setup process and going through extra-hassle. At the same time, make sure your cooler fits the case provided, as well. Take measurements and crosscheck to be safe. If you don’t have an idea about the cooler, you can always ask the manufacturers before you buy one. They are usually quite helpful in such cases. 
  • 3 or 4 pins? Coolers may have 3 pins or 4 pins, and which one you buy depends on the motherboard. Most CPUs have a 4-pin slot, and this offers good control, but we know users who still love their 3-pin coolers because they enjoy more control. Plus, 3-pin coolers can fit the 4-pin slots as well. So, here the choice is completely yours.


Do you need a CPU fan? Yes, if you are going to overclock your computer. Which type of CPU cooler do you need? It all depends on your usage! Remember, liquid coolers are the most efficient ones on the market. Make sure you buy one of those.
