If you want to enhance the use of Core i9-11900K, when you have to use a cooler for i9-11900K to get a full 360mm radiator. 

The 11th Gen Intel Core processor family uses the latest Cypress Cove microarchitecture cores to improve efficiency and performance. According to Intel, the new architecture brings an increase in performance compared to similar models of the 10th generation and is even capable of operating at higher frequencies.

What are CPU coolers?

Processor coolers remove excess heat generated by computer components. The CPU coolers for i9-11900k gives guarantee proper temperature maintenance for a running PC. Remember that too much heat can damage your CPU.  It might even lead to a chain reaction that will create more problems for the computer. Of course, powerful computers require more efficient coolers. Those who are looking for products with a good capacity will have to invest in an adequate model.

Finding the perfect CPU cooler for the 11th gen can seem difficult. If there are many processors or multiple choices, for this manner you must choose the 11th gen. It should be understood that some coolers are suitable for certain constructions, while others are not necessarily. 

The main task of the CPU cooler is to prevent essential components rigs and enhance the rig’s lifetime by ensuring that everything is under control within the safe temperature band. The cooler depletes the i9-11900k processor heat through a huge surface area and utilizes its liquid-based system to keep it operational as well as cool.

The basic principle to choosing CPU coolers

Air or liquid CPU coolers? Which brand to choose from? These are questions that bother many newbies. The best CPU coolers for i9-11900 may vary from model to model. You will have to choose between an air cooler and a liquid cooler.

  • Air-cooled CPU coolers

The most common form of processor cooling is the air-cooling CPU cooler. The equipment uses fans because of their efficiency and low cost. In fact, the best CPU air cooler for the 11th gen is versatile enough that it can handle intense processing.

  • Liquid CPU coolers

Liquid CPU coolers for the 11th gen offer better performance compared to the model. Liquid cooling can conjure up the image of hardcore technicians running PCs with crazy configurations.

Power users and overclockers are more inclined to go for that extra heat reduction offered by liquid cooling. While many gamers don’t want to install a liquid setup, many of the best CPU liquid coolers prove to be fairly easy to integrate with standard PC versions.

Liquid cooling systems are generally quieter because they push heat out of the case rather than inside like air systems. Their better thermal conductivity allows for more cooling with less fan power.

How to choose the best CPU cooler for i9-11900k?

Most standard CPU coolers for i9-11900k come with inexpensive aluminum instead of the higher-performing copper heatsinks. So if you are looking for good cooling and less noise for your microprocessor, you will need to invest in a better-performing cooling system. You can keep these important points in mind that will help you get the best first-class coolers for your i9-11900k:

  • Premium quality: 

First of all, you need to choose the best CPU cooler for i9-11900k that shows superior quality. Look for the option that is recommended by a large number of people. Also, the chosen model must have an expanded design and be equipped with dual fans. 

  • High compatibility:

Also, have the best CPU cooler for i9-11900k, which shows high RAM compatibility if installed with single fan mode. It should have recessed bottom fins and show wide compatibility with some of the premium and high-end RAM modules.

  • Secured mounting system:

Experts have recommended getting their hands on that CPU cooler for the 11th gen that shows a secure mounting system, and in this way, users can get features of safety, quality, and ease of use. Furthermore, a secure and firm mounting system offers the appearance of perfect contact pressure and maximum user comfort.

Things to look at the time of buying


When buying a cooler for the 11th gen, first, check its performance and capacity for cooling. It is also important to consider installing the different components that take part in the cooling system’s influence and performance. 


Unless you have a passive heatsink, the cooling system will make noise due to the presence of fans that expel heat, some outside the component or even outside the case. The noise will depend on the size, number, and power of the fans that the system incorporates, which must be reflected in the product’s technical specifications. It will also depend on how much heat the system has to dissipate; the higher the CPU is; the more revolutions the fan will have to reach to expel the heat from the component.


The dimensions of a cooler for i9-11900k will depend on the model that we want to choose. However, the size is only limited to the area near the CPU, while the most powerful heatsinks are typically larger. With a liquid cooling system, you will have to make room for the radiator on one side of the case. The all-in-one liquid cooling or low-profile heatsink with a small radiator gives the desired space that the airflow from your computer doesn’t stop.

Ease of installation

Air cooling systems are the easiest to install; after all, all you have to do on all models is tighten the screws connected to the CPU and the motherboard. This does not mean that AOI liquid cooling systems are also very easy to install since when they come fully assembled, we will only have to worry about coupling the fan to the computer case and the cooling unit to the CPU.

Of course, in both cases, you will have to consider the dimensions of your computer case and the rest of the components to see if the system fits without problems. However, when we talk about custom liquid cooling systems, things change since the assembly and maintenance of these systems must always be left to the experts. Although they can be much more customizable and versatile, they are not recommended for people who do not experience this field.


If we start searching for a cooler for the 11th gen, we can find basic and premium versions, either for liquid or air cooling systems. In general, air cooling is cheaper in both the most basic and advanced models. 

However, OIA liquid cooling is becoming cheaper, and it will end up being standardized in all equipment. The best suggestion is to buy a cooler for i9-11900k that seems budget-oriented.

How Do I Pick a Good CPU Cooler for i9-11900k?

Having decided on the type of equipment needed to cool your system fully, you should pay attention to the following aspects. If you do not know how to choose a cooler for an 11th-generation processor, please note that we only disclose the key parameters, but we cannot give any recommendations, not knowing what kind of hardware you have. So:

Radiator: Today, aluminum models are found less and less; copper is more often used. The second material has better thermal conductivity and guarantees more efficient heat dissipation.

The number of heat pipes: These elements contain a low-boiling liquid, which evaporates and condenses at the other end, which will allow removing unnecessary heat from the source and transferring it to the radiator. In expensive active coolers, there are up to 6 such elements, whereas, in premium ones, there are more than six.

Mounting method: To install passive and active coolers, you can use latches, double-sided mount types, bolts, and silicone mounts. The latter option is prioritized due to vibration absorption.

Fan quality: The most common 120mm fans can have different bearings: sliding, rolling, and fluid dynamics. The last bearings are filled with a special fluid that guarantees good mobility during the fan’s rotation.

Turnovers: The lower the minimum – the wider the adjustment range, and the higher – the more effective. In this case, the diameter is closely related to the size of the fan. It is considered the norm from 1000 to 2500 rpm.

Therefore, it is worth paying attention to any modernization of the cooling system; otherwise, the consequences can range from excessive spending of money to overheating the Northbridge or processor power supplies. However, competently assembled cooling will give both silence and a constant temperature for the processor.

Final words

The above are some of the best CPU Coolers for Intel Core i9-11900K.

The Intel Core i9-11900k comes with the most powerful CPU system that boosts speed because of its high degree bound performance of single-core CPU.

Most gamers didn’t recognize that they didn’t spend extra charges to acquire a high-end processor cooler for i9-11900k. They don’t even think that a valuable CPU cooler brings a positive experience and enhances the CPU life.

Thus, even though coolers are secondary or not tertiary parts in any system, their purchase must be approached with all seriousness. There are a lot of factors to consider: from the size of the fan to the backlight. If you do not know which CPU cooler for the 11th gen to buy, do not hesitate to ask even absurd questions to the consultant, because their job is to answer them
