5 Best CPU Coolers Under $50 in 2021

(Image credit: DeepCool)

One of the most commonly frequently asked questions among PC builders is how to provide a good cooling solution. As we all know, the two most energy-consuming components are the GPU and the CPU. And unlike the GPU, most of the time, the processor needs a good aftermarket cooler. Nevertheless, maintaining your processor under good temps doesn’t always require high-end coolers; in fact, you can do it with some CPU coolers that are under $50.

1-Arctic Freezer 34 eSports DUO (Best Overall)

The Arctic is a brand that has been offering cooling solutions for our processors and graphic cards for quite some time now. While they are mostly known for their powerful liquid coolers, such as the 280mm AIO Liquid Freezer II, in the present article, we will tackle a less expensive yet impressive cooler: the Freezer 34 eSports DUO!.

What makes it good?

Available in various colors: white, yellow, green, and red. This kit is compatible with Intel and AMD sockets, excluding the AMD TR4 socket. It is also equipped with PWM PST for synchronous fan control and privileged with an extended life span and lower power consumption. The dimensions of this cooler will not cause compatibility concerns with some RAM kits, which may be high.

Indeed we find here two Arctic BioniX P120 fans providing optimized static pressure and updated thermal-coated heatsink. Note that these fans are relatively quiet since they can run at a maximum of 2100 rpm for 28 dB, with a 0dB mode for a PWM signal less than 5%. These fans also benefit from a new precise and durable double ball bearing.

As for the assembly, it is clearly perfectible with better differentiation between the fixing system’s spacers, via either separate bags or via an inscription on the spacers themselves.

With its outstanding cooling performance and low noise level, this cooler will soon be on top of your list!  We are faced with a cooler that we believe offers good value and a very refined design for a relatively low price range.

What could have been better?

The Arctic Freezer 34 eSports DUO lacks ARGB/RGB lighting effects, and the compatibility range is narrowed. However, the lack of these features is justified considering its amazing price tag.

Pros
  • Quiet
  • Affordable
  • Straightforward installation process
Cons
  • No RGB

2-Cooler Master Hyper 212 RGB Black Edition (Most Stylish)

Once again, the legendary ‘Hyper air cooler’ surprises us with an interesting solution for processors’ heat dissipation problems: The Cooler Master Hyper 212 RGB Black Edition, which does look not only great but also very functional.

What makes it good?

Performing almost as good as some expensive air coolers, the Cooler Master Hyper 212 is a perfect CPU cooler equipped with an RGB LED lighting system. Also, it consists of a wired RGB LED controller, allowing you to customize colors and effects with a simple touch of a button.

With its superb design, incredible light effects, and high air cooling performance, this cooler has it all at once. Its Gun Metal black design brushed nickel fins, and compatibility with the latest CPUs will make it worth every penny.

3-BeQuiet! Pure Rock Slim (All Rounder)

Again with the interesting brand of power supplies, PC cases, and cooling solutions, ‘BeQuiet!’ Another cooler while remaining quiet got us hooked. The “Pure Rock Slim” is this brand’s representative for the best CPU coolers at a low price.    

What makes it good?

The Pure Rock Slim consists of a 92 mm fan that contains seven optimized blades to ensure maximum airflow by limiting turbulence which can be noisy. Thus, this one provides quiet cooling with excellent cooling efficiency. In addition, this device never exceeds 25.4 dB, even when running at full speed, i.e., at 2000 RPM. Hence, it ensures the best price/performance ratio with a high cooling capacity of 120W TDP.

It consists of three high-performance 6mm heat pipes with aluminum caps transporting heat to the most efficient fin dissipation points. With its high-quality bearing, the PWM fan offers the perfect association between cooling solution and quiet operation.

Thanks to its asymmetric and compact design, the Pure Rock Slim is a fantastic option for mini ITX builds.

What could have been better?

The overall design of this cooler doesn’t have anything fancy. And you can’t rely on it to improve the look of your gaming rig. Despite that, the company succeeded in providing an interesting product.
