How many CPU Coolers do I need? In-depth Guide

How many CPU coolers do I need?

First off you only need 1 as that’s exactly how many you can fit to directly cool your processor, but you’re probably asking about case fans as those are the ones that help with airflow anyway, let’s start with going through each of the questions above.

  • Do you have a small business?

If you do, it might be a good idea to have an extra case Fan to make airflow better and cooler for the whole build including the GPU, smaller cases tend to accumulate more heat and need more cooling as there is not much room to let the heat out.

  • How powerful is your CPU and GPU?

If you’re on a high-end PC build, it might be advisable to have additional fans, although this isn’t a “necessity” as most components already come with fans/coolers that are generally good enough to keep them working as long as you don’t overclock, however if you have other factors that can affect the heat (such as a small case or very hot weather), it may be a wise choice to use an extra fan.

Very hot weather may require more cooling for your PC build.

This is another important question when it comes to how many case fans you need. If you’re overclocking, having at least one extra fan can help keep temperatures low and under control.

However, if you’re really overclocking, in our opinion it’s better to buy a good and powerful aftermarket cooler than to buy an extra fan (although there’s nothing wrong with doing both!).

The CPU cooler directly cools the processor, so having a good one while overclocking is much more efficient than a bad/mediocre and just having a second fan in your build, that’s because the second cooler helps with airflow and overall heat in the build. the whole system, while it does have an impact on your processor’s temperature, it’s not as great as cooling it directly like the CPU cooler does.

Cooler and Case Fan Recommendations

We recommend getting a high powered cooler as it has the most impact and only a mediocre case fan as they are meant to aid airflow and not as impactful as cooling your components directly.

For the coolers, we recommend getting one of these:

  • CoolerMaster MasterAir MA624 Stealth
  • CoolerMaster MasterAir MA410M

These are well known high quality products that get the job done, they do it so well that you probably don’t need a case fan at all (although we still recommend it if you can afford it).

For the case fans, we recommend a regular one as we mentioned before, their impact isn’t that great as such, it doesn’t really matter which one you buy as long as you get it going.

Do I need 2 CPU coolers?

We do recommend that you always take an extra fan, there’s nothing wrong with that and it will never be harmful, it’s just a question of whether you’re willing to buy it or not!

Which coolers for my CPU?

The answer depends on your goal. If your goal is to replace your current cooler with a more powerful aftermarket cooler then you will want a really powerful one as the impact of it is quite big as these can be quite expensive but well worth it.

If you go for an extra case fan instead, you can go for a cheaper option between 20-25$ as these are just to improve the airflow in the case and you don’t need a very expensive product for that.

How do I know if my CPU cooler will fit?

The only way to find out is to know your CPU socket and check if it’s in the cooler compatibility list. Generally this can be done by checking the manufacturer and most likely also the website where you bought/purchased the cooler.

What socket does my CPU use?

This can be found quite easily by Google, your CPU model like “Intel I5 12600K Socket” and the first result will probably be an Intel or AMD website with all the information about your processor including the socket.
