Review of the Best CPU Cooler for the i9-11900K

It matters a lot how effectively the cooler cools your CPU and manages the temperatures within. When it comes to a high-end CPU like the i9-11900K, you should be dead set on obtaining the finest choice available.

Before we get into it, let’s have a look at this CPU in general.

The Core i9-11900K is an 11th-generation Rocket Lake CPU. After six hard years, Intel has finally released its first microarchitecture processor. The 14nm technology is used in the Cypress Cove architecture of this CPU. It is Thunderbolt 4 compliant and supports the PCIe 4.0 interface as a processor.

When compared to the preceding 10 core Comet Lake series, the performance has improved by 19% IPC. In addition, GPU performance improved dramatically in the 11th Gen series. This is a significant improvement over the preceding 10th Gen, which had poor integrated graphics performance.

It’s not over yet, however. This i9-11900K is a beast of a processor that may offer you a significant gaming boost. When it comes to the all-core boost, it runs at 4.8 GHz, and for dual-core, it effortlessly exceeds 5.1 GHz. I believe this model will outperform AMD equivalents such as the Ryzen 5900x, especially if overclocking is attempted. Even if you try, you won’t be able to overclock above 6.0 GHz in certain situations. Now, since the OC potential is so great, you must be careful and cautious.

However, you may easily get disoriented in the market, bobbing in a sea of choices. The objective is to choose the best one out of all of them. And, my buddy, I’m here to assist you with that problem.

So let’s not spend any more time and go straight into my analysis.

But first, have a look at our most recent article on the best CPU Coolers for the i5-10600k.

The following are the top nine CPU coolers for the i9-11900K:

NZXT Kraken Z73 is the first in the NZXT Kraken Z73 series.

There’s a reason I chose this cooling system as my top choice. Its dependable performance, along with the most up-to-date features, makes it an excellent choice.

The following are the specifications for this NZXT model:

  • Radiator diameter: 360 mm
  • LCD that may be customized
  • 3x 120 mm Aer P fans


Check out the current price of the NZXT Kraken Z73.

NZXT’s Kraken series of CPU coolers is regarded as one of the most prestigious in the PC hardware industry. I had previously used this model for the 10th-Gen Comet Lake series, and it had worked very well.

It’s now a powerful alternative for the Core i9-11900K as a flagship cooling solution.

Let me explain why.

This CPU cooler is excellent in terms of quality and construction. It has both stunning aesthetics and high-end functionality. The customisable LCD on the pump face displays such stunning graphics. This LCD can also display different statistics such as CPU temperature, fan speed, pump speed, and so on.

You may also use the NZXT CAM software to personalize the screen with pictures, animations, and even GIFs.

As an AIO cooler, it supports all of Intel’s most recent socket types, thus there are no compatibility problems.

The 7th Generation pump is at the core of this cooler, ensuring consistent performance and stability. A cold copper plate with a high-quality thermal compound is included in the pump base. You’ll also be able to spin it in whatever direction you choose.

The 3x fans on hand are of excellent quality. They move at a reasonable pace and are capable of extracting hot air. They may, however, be very noisy at maximum RPM.

The cooling performance level was precisely what I anticipated when I tried and tested this AIO cooler in my i9-11900K setup. The cooler kept temperatures under control, especially while overclocking. It managed to keep my GPU under control even while I was gaming in 4K.

The only drawback you should be concerned about is the cooler’s price. But that’s only true when you’re strapped for cash. Overall, this is by far the best choice for an Intel 11th-Gen setup, since it comes with a 6-year warranty.

EK-AIO Elite is the second option.

When it comes to keeping your rig cool, watercooling is always an option. The model performs the same thing when it comes to appropriate handling.

It now has the following table specifications as a water-cooling solution:

  • 500-2200 RPM fan speed
  • 36.4 decibels of noise

The following are the noteworthy specifications of an aluminum radiator:

  • Fan speed ranges from 500 to 2200 RPM.
  • Radiator made of aluminum
  • 36.4 decibels decibels decibels decibels decibels decibels decibels


Check the current price of EK-AIO Elite.

This EK watercooler stands out among high-end cooling systems. This was included to my list because of its excellent production and remarkable capabilities.

It differs from other coolers on the market in terms of design. The reason for this is because, unlike other coolers, it has a proprietary built-in solution. It indicates that this model is a little different. This is especially true of the pump, which is based on the company’s SPC series.

The cooler is very sturdy in terms of construction. In addition, the 360 mm radiator has a strong and compact feel about it. The fans on the interior offer excellent ventilation.

After using this cooler in my 11th-Gen Intel i9-11900k setup, I believe it performs well. I mean, I’m the kind that loves to push things to their boundaries. I was hesitant to use this CPU at first, but after hearing from a few gaming friends, I decided to give it a go. And, thank God, everything came out fairly nicely, owing to this EK model that did a great job of optimizing the temperatures.

It was also simple for me to set up the cooler, since there were no clearance problems. Although it may obstruct a DIMM slot in certain setups, you have the option of rotating the pump. As a result, there are no major issues.

Although it may not be life-threatening, no one enjoys loud noises. At 100 percent RPM, the fans may be very noisy, but I’m confident you’ll be able to manage it if you’re careful.

In my view, the 5-year warranty is fantastic. However, budget shoppers may raise an eyebrow at the price. If you’re not one of them, I’d say there’s virtually no reason not to purchase this water-cooling system.

3. Corsair H150i Elite Capellix (Corsair H150i Elite Capellix)

Mate! Are you searching for a way to keep your all-white gaming setup cool? I’ve found the ideal solution for you.

The following features are included in this model:

  • Fan speed ranges from 400 to 2400 RPM.
  • Fan profile with no rotational speed
  • ICUE software is in charge.
  • 3 ML120 Corsair fans


Check out the current price of the Corsair H150i Elite Capellix.

My favorite brand is Corsair. I’ve tried a lot of their goods and, to be honest, I’ve never been disappointed. They’re a huge deal in terms of PC hardware.

This model, in particular, is one of those high-performance choices that can meet the demands of high-end gaming setups.

For a number of reasons, I included this liquid cooler to my list. It has the potential to significantly improve the visual value of your gaming setup.

The cooler, in my view, is excellent. The white radiator, pump, and tubing, in particular, go well with the all-white motif.

Now, if you’re an RGB fanatic, I’d have to say that this is the finest choice available. The pump is equipped with 33 LEDs to provide beautiful illumination. You’ll also notice that each of the three fans has eight LEDs. Overall, the lighting brilliance is excellent when they run at full speed.

Besides, these fans perform a decent job of cooling. These fans provided enough cooling for my i9-11900K setup. These fans, however, may be a touch loud at times. However, this isn’t a significant problem since the temperatures were well-adjusted. And I performed all of this tweaking using Corsair’s ICUE program.

It was always responsive as software. There were no bugs at all. You can adjust fan speeds, alter lighting patterns, and so forth using this. What I loved most about this option was how simple it was to set up. It just takes a few minutes.

Furthermore, as a liquid cooler, it’s a cost-effective choice with high-end specifications.

Noctua NH-D15, Noctua NH-D15, Noctua NH

Let’s speak about an air-conditioning system right now. Some air coolers can compete with liquid coolers on a level playing field. This Noctua model is the same as the previous one.

It has the following specifications as a cooler:

  • NF-A15 fans (two)
  • 6-Heatpipe layout
  • RPM of the fan: 300-1500


Check out the current Noctua NH-D15 price.

Noctua makes some of the finest air conditioning systems on the market. At least three to four of the top air coolers presently on the market are from this company. This specific model, though, is one of their flagship versions.

It has a dual-tower heatsink and a relatively small footprint.

It is, in my view, a much superior cooler than its predecessor. That’s because, on the vast majority of benchmarks, this cooler stood tall and outperformed its predecessor.

The most exciting aspect is:

The 2x fans that are included are of the highest quality. They are silent and effectively remove hot air from the processor.

Despite this, there are a few things you should keep in mind. If your build includes higher RAM modules, for example, there may be some clearance problems. Furthermore, the cost of this model may not be affordable to everyone.

However, in my view, you can’t find a better air cooler for an i9-11900K construction than this one. It’s an excellent substitute for high-end water cooling systems.

Also, have a look at my top-recommended motherboard for the i5-10600k.

NZXT Kraken X73 (No. 5)

This is the second liquid cooler from NZXT’s Kraken series that I’ve added to my collection. The primary reason for this is some outstanding performance.

The following are the specifications for this NZXT model:

  • Noise level: 21 decibels (dBA)
  • CAM integration in its entirety
  • 3 × Aer P aficionados


Check out the current price of the NZXT Kraken X73.

You may buy it for your i9-11900K setup as an enthusiast-grade AIO cooler. It has excellent cooling capabilities as well as excellent functioning.

Let’s speak about the build-up for a moment.

The materials utilized in the building proved to be very durable. The radiator is said to be constructed of top-class aluminum in the spec sheet, which I believe is justified. It has great aesthetics throughout, with a cool blackish tint.

The RGB implementation in the pump face is much more interesting. The pump has been enhanced by 10%, resulting in a vibrant RGB ring with top-notch brightness. And you can fine-tune the lighting using NZXT’s CAM program, which is very adjustable.

In terms of quality, I’d say it met or exceeded my expectations. The minimal acoustic output is what struck me the most.

Unfortunately, since it is enthusiast-grade, the pricing is expensive. However, this is only partially justified due to the excellent performance.

ASUS ROG Ryujin 360 RGB (No. 6)

Let’s have a look at a cooler from one of the most well-known PC hardware manufacturers. This particular brand’s cooler offers RGB with performance.

The model, however, attributes the following specifications:

  • RPM of the fan: 400-2500
  • 29.7 decibels (dBA) of fan noise
  • 77-inch OLED display


Check out the current price of the ASUS ROG Ryujin.

ASUS as a brand seldom disappoints me when it comes to its components. Because everything I’ve purchased from them thus far has been excellent. They established a reputation for themselves in the high-end AIO market with their cooling solutions. Especially with their cooler, which is part of the ROG line.

In terms of specifications, this model has several sophisticated features. It features three Noctua fans, and the greatest thing is that they’re all rubber mounted. Even when the fans are running at maximum RPM, such installation will ultimately result in no vibrations.

The CPU block is constructed of plastic and has ventilated areas to enable hot air to flow freely.

The OLED panel is the greatest feature of this liquid cooler. You may see system statistics and upload images or GIFs. You may also use the Live dash program to customize this interface.

The noise output is excellent, however the 60mm pump fan may be very noisy at times. Aside from that, this ASUS liquid cooler is capable of competing with most high-end cooling systems.

NZXT Kraken X63 (#7)

This may be the finest choice for your i9-11900K gaming setup if you want a mid-ranged alternative.

The following are the specifications for this NZXT model:

  • Aer P fans (two)
  • RPM of the pump: 800-2800
  • Pump from Asetek’s 7th generation.


Check out the current price of the NZXT Kraken X63.

I can’t seem to stay away from the NZXT brand. Their Kraken line includes some of the best liquid coolers on the market. As a result, I had to include this model as the third from the same brand on my list.

That said, it’s the kind of AIO that can easily keep the temperatures of a gaming PC in the enthusiast class under control.

The lighting for this option is very lovely, since it produces an RGB infinity lighting effect on the pump face.

Now, since we’re on the subject of pumps, this model uses the Asetek 7th-Gen pump. The internals of this pump are made of plastic and copper, and it is very robust. The tubes that come with it are also nylon braided.

In terms of performance, I’d say it’s enough for the i9-11900K only if you use it often or don’t overwork it. For example, if you’re into severe overclocking, I wouldn’t recommend using this.

Overall, though, it is very helpful as a bundle.

It’s renowned for making whisper-quiet air conditioners. As a result, this model from them has the following specifications:

  • PWM fan, 135 mm
  • Heat pipes made of copper
  • 21.6 dBA maximum noise


Dark Rock 4’s current price may be found here.

The Dark Rock Pro 4 is well-known. One of this brand’s finest coolers, with excellent cooling performance and almost little noise.

In terms of productivity, this model is only behind that model as an air cooler. It has a sleek blackish appearance. The whole metal structure seems to be well-polished.

This cooler’s 135mm fan is an excellent feature. Even under heavy loads, it remained steady and produced minimal noise throughout my tests. The anti-vibration rubber cushions were largely responsible for the steadiness.

The main issue with this air cooling method is that it may cause certain DIMM modules to get obstructed. But only when the modules are too tall.

In most cases, purchasing this air cooler is a wise decision.
