Whether you are building a new PC, looking to upgrade your hardware, or are suffering from performance issues, a case fan for your computer could be all that you need.

A PC case fan isn’t just necessary, it is vital.

Before we start, it is important to note that tiny HTPC systems, low-powered Raspberry PI, or even some basic office units do not generate enough heat to bother with case fans. Computers that output low amounts of heat can sometimes take advantage of passive CPU coolers to great effect.

That being said, airflow is the best way to keep the temperatures down in your computer, so generally case fans are always beneficial and should especially be considered if building a gaming PC.

Do I need a case fan for my PC?

Are you currently suffering from a slower PC? High heat can affect the performance of a PC and if you have poor airflow this will not only impact your gaming but can damage your components over time.

No need to panic, a PC tends to shut down when it hits critical temperatures and modern components can run quite hot but that doesn’t mean you shouldn’t provide them with better airflow.

Maybe you are building a new gaming PC?

In that case (sorry) you will find that a lot of PC cases tend to come with pre-installed fans inside! Always check this before buying and if the model you would like has none, just buy some.

PC case fans are cheap and you only really need 2-3 for optimal airflow. Even a single-case fan would obviously be better than none but we like to recommend at least two to bring your components fresh air constantly.

Do you have an open-air case?

You may have a PC case that is not considered an ‘enclosure’ which can sometimes mean you may not need a case fan.

Why computer fans are necessary

A computer case fan boosts the airflow through the case and helps keep the ambient temps inside down.

You generally want one fan sucking fresh air into the case and another pulling air out in a nice linear motion.

A standard PC case, also known as a mid-tower, always has a slot at the back for a fan and several at the front, giving you optimal positions for your fans to push air through your precious components.

A CPU will tend to come with a stock cooler and a graphics card will have a heat sink and fans on top of it, so your components are being cooled, case fans just assist.

Adding case fans will potentially increase the noise

If you already have fans or alarmingly have zero, you should know that adding fans into the mix will increase the overall noise of the build.

You can tweak the settings of the fans, setting up the curves and making sure they only blow as fast as they need to. This will give you near silence when your PC is idle, however, could be quite noisy during full load.

While we can sit and debate the different types of cooling and builds available, generally speaking, a case fan is very important to the system builder.

You need case fans to efficiently and economically cool the interior of the PC, it is as simple as that.
