Best CPU Air Coolers

A PC’s lifespan and performance depend on the cooling system. The better designed the ventilation system, the better the health of your system. CPU coolers are subdivided into two main categories; Air and Liquid cooler. The air coolers are the oldest, simplest, and most popular solution for meeting your CPU cooling demands. It consists of a heatsink attached to a fan (or multiple fans), and the whole assembly is coupled to the CPU via a thermal paste and mounting system. If you are looking for the best air cooler for your CPU, you are in the right place. We will review some of the best available options to maximize your PC cooling. They are usually the most economical and affordable solution for average and high-end consumers.

Liquid coolers are expensive and complex equipment that consists of a radiator, a pump, and fans as an all-in-one (AIO) solution. Their primary target market is elite users and enthusiasts. Optimum ventilation is accomplished by cooling all the PC components that are prone to getting hot. These include CPU, GPU, Motherboard, and hard drives. The most critical component of them is the CPU. It is the processing house of your PC that processes all instructions received from components and applications. General usage CPUs often come with a stock cooler that is usually enough for low-level workloads. You should consider an aftermarket best cpu cooler for moderate to high-level workloads to acquire the required performance and longevity you seek.

As we are focusing on the masses today, our focus will be on the air coolers. We will discuss some tips to ease up the selection process for the best cpu air cooler.

Quick Shopping Tips:

Purpose: The most obvious question that arises in mind is air cooler better or the liquid cooler? The answer is not so simple. It all depends on your utilization purpose. The air coolers are a superior selection for value-centric users that want to acquire good performance at an economical price. The liquid coolers are less noisy, premium, and expensive and are not recommended for average users due to the higher performance to price ratio.

Price: Your budget dictates the type of cooler you can buy and the features it carries. It is often wise to spend as little as possible on coolers so you can spend more on CPU, GPU, and other performance-enhancing components, as they will have more impact on overall performance. Air coolers are the most obvious choice to budget users, while elite users can get the best performing cooler with the latest attributes.

Thermal performance: The most critical step in cooler selection is figuring out the optimal requirements of cooling. The best practice is to get a cooler with a cooling capacity of 1.25x the TDP of your CPU. That way, you leave enough headroom for overclocking your CPU without getting into trouble. If your cooler capacity is less than the maximum heat load of your CPU, you won’t be able to overclock it, and the CPU will keep throttling to lower speeds.

Noise: The PC consists of multiple components that may produce noise; these include GPU fans, case fans, hard drives, etc. No one likes other noisy equipment to add to the overall noise. Noise levels should also be considered as they will hamper your immersive gaming sessions or other creative tasks requiring immense focus and serenity.

Aesthetics: Everyone appreciates beauty and the best cpu cooler is the title that goes to the cooler that is the quiet and cool performer but the aesthetically pleasing. You might want to become the center of attention with a cool-looking cooler or do it for yourself; it all depends on your desire. An attractive design integrated addressable RGBs, and color scheme all affect the overall appeal of your PC.

Cryorig was formed less than a decade ago, and it made its name as a dependable cooler manufacturer. Previously we reviewed the Cooler Master Hyper 212, which was our best budget pick. Cryorig H7 offers almost identical performance benefits and is the Best Hyper 212 Alternative for our users at a slightly higher price. The thing where Cryorig shines is the height of the cooler. It has only 145mm top height and is effectively the smallest tower heat sink design featuring a 120mm fan size.

Another aspect that highlights this best air cooler is the unconventional heatsink design part of its performance and appeal. The high five fin construction uses patented accelerated jet airflow and turbulence reduction technologies to optimize airflow and enhance the heat efficiency of the cooler. On top of that, the asymmetric tower design allows ultimate RAM clearance and full compatibility for taller RAMs.

The cooler support processors with a maximum thermal dissipation of 150W are in line with most mid-level processors. We can add additional cooling capacity via adding another fan in the push/pull config but not recommended. The noise level is moderate as expected but will rise with another fan. At this price, it’s unfair to ask too much from a cpu cooler. For people needing an economical subcompact cooler for their mid-level rigs, Cryorig is the way to go.


With the ever-increasing demand for higher-end processors, their heat dissipation is also increasing steadily. The competition for the highest clocks, multiple cores, and the fastest processors has led to a massive inrush of high TDP CPUs. The demand for economical higher capacity coolers is ever rising. Liquid coolers, however, provide premium and high-capacity cooling services, but they are pretty expensive and don’t offer extended warranties like air coolers. Due to their simplistic design and high performance to price ratio, air coolers remain the most popular consumer choice to date.

We have further segregated our recommendations into two main categories, the best and the economical. The best air cooler if money is not a problem is the Deepcool Assassin III. It has the highest thermal dissipation capacity of 280W, ample for overclocking even the most power-consuming flagship CPUs like 5950X. For general users, it’s overkill and also very expensive. Cryorig H7, on the other hand, is reasonably priced and is our budget pick for the rest of the users. It has an excellent thermal efficacy of 150W that can cool mid to high-level CPUs effectively. Overclocking, however, is limited to mid-range CPUs only due to thermal limitations.
