If you want your CPU to perform to its full capacity, you’ll need to keep it cool. Modern CPUs create lots of heat when working. Unfortunately, excessive heat is bad for electronics and can cause your CPU to slow down, crash, or even burn out in the long run. This is why when building a new computer or upgrading an existing PC, it is important to use a CPU cooler in order to ensure your processor is protected.
Thankfully, CPU coolers do not have to be expensive, and there are several models that do a great job keeping your CPU frosty cool while running for under $100. To help you find a great deal on your next CPU cooler, we compiled a list of our favorite CPU coolers available for 2021.

Choosing Your CPU Cooler
If you are building a PC on a budget, your object should be to buy a CPU cooler that is powerful enough to keep your processor safe and running quickly without spending money that could go towards upgrading a different component. Here are some things you should consider before you begin shopping.
- Size of PC Case: Especially if space is limited in your build, you will want to pay careful attention to the size of your cooling system. You may discover that you can automatically eliminate some CPU coolers you are considering simply because they will not fit in your computer.
- Type of Processor Socket: The CPU cooler mounts directly to the bracket that holds your computer’s processor in place and should be attached with thermal paste. Many of the coolers on our list are universal and fit Intel and AMD CPUs of all types. However, some only fit correctly on specific brands or models.
- Type of CPU Cooler: There are two ways that the CPU coolers listed below get the job done, sing liquid or air. Traditional CPU coolers use a fan to circulate air onto a CPU. A liquid cooling system uses water or another liquid to cool the CPU. Because the liquid creates a much more efficient heat transfer, liquid cooling systems tend to be more effective and quieter. Liquid cooling is more expensive than air cooling, but recent advances have led to liquid CPU coolers becoming much more affordable. You can even pick up an all-in-one liquid cooling system for under $50.
Picking the Best CPU Coolers
With so many similar options to choose from, picking the top cheap CPU coolers for 2021 was not a simple task. Here is what we considered while reviewing each option.
- Design: A well-designed CPU cooler is easy to install, provides enough power to get the job done, and takes up a minimal amount of space in your PC case. Also, it doesn’t hurt to have lighting or other design features that make your PC look really cool.
- Performance: The most important part of reviewing a CPU cooler is figuring out how well it gets the job done. The cooler your processor runs, the smoother your PC will run as well.
- Noise Level: A noisy computer can ruin the vibe in a room. We give the edge to CPU coolers that do their job as quietly as possible.
- Control: Especially for power users looking to overclock their processor, having total control over the speed of the CPU fan is a big help.
Now that you have an idea what to look for, here are the best cheap CPU coolers to buy for your PC in 2021.

The fan is effective at both airflow optimization and air turbulence reduction thanks to the Hive Fin System. The product also has a larger than ordinary air dispersion area. However, it is not the most compact cooler with a 140 mm fitting. So make sure it fits your case before investing in the Cryorig H7 Tower Cooler.
The Cryorig H7 Tower Cooler performs better than expected for such an affordable price thanks to three copper heat pipes. The pipes help balance the cooling system. The fan uses an optimized hive fin structure, making it effective and dependable. The bearings are produced for improved airflow and lower operating temperatures. When combined with the Quad Inlet technology, the air intake is increased.
You may want to take the product to a professional for installation. It is not considered the easiest to install into an existing PC. If you do decide to self-install, make sure the thermal paste is applied to the processor evenly—the included spreader isn’t the best. Also make sure the old paste is removed entirely, even from the back of the processor. The product also includes a six-year warranty for peace of mind.
With unique designs and patented technologies, the cooler is recommended for most users who need an affordable solution which runs with low noise and which comes with a consistent warranty policy.
