Best CPU Cooler for i9 11900K


The i9 11900K is among Intel’s latest processors designed to offer the best possible performance to its users. The i9 is already a dominant processor no matter for which series you go for it.

The processor handles the load extremely well and performs great in test and everyday usage however as we all know Intel also releases a K series for every processor that they launch. The K series CPU is built to perform extra with much higher overclocking capabilities and higher clock speeds.

The Intel i9 11900 even without higher overclocking capabilities is a solid CPU. It has 8 cores and 16 threads which are enough for modern applications and with its cache memory of 16MB and Intel Rocket Lake architecture that is based on 14nm+ is proven to be quite helpful in heavy scenarios. The K series 11900 took that step further which can overclock the processor up to bring GHG.

However to provide this amount of speed the processor requires more, energy which brings the TDP of it to 65W which can go up when overclocked. During this process, the one main thing that is constantly making an effect on your CPU performance is the heat.

The more the heat is produced by the processor which is unable to escape the more you will experience slowed down performance and it can also make an effect on your CPU life expectancy. The stock coolers from Intel are not made for handling this amount of heat with a powerful processor like the I9 11900K so it is better to find something more effective in keeping the heat away.

There are a bunch of coolers that are available in Online shops or Local stores which can certainly work with the I9 11900k however with a processor like this it will also perform the same as the stock Intel cooler which is not what we want since it can damage your CPU. So I have piled up some of the best CPU coolers for I9 11900K which are durable and effective. So let’s take a look at them.

There are two 120mm fans mounted on the radiator both of them are capable of spinning at max 2300RPMs which is doable. Connected to these two fans is the high-quality rubber tube which cannot be bent easily so that the liquid can travel easily. The pump uses a copper base which absorbs the heat from the processor.

Best All-Rounder CPU Cooler for I9 11900K

If you don’t want a good Liquid CPU cooler but instead looking for the best air cooler then you should take a look at this cooler before looking for other options. At first, the name and the cooler do not sound familiar in any way but this cooler has gained a lot of positive ratings for its performance.

The design is not the best part of this cooler which is why you have to make some compromises here. So this cooler comes with beige color on its fan chassis and the stainless aluminum heat sink on its back. The fan is painted with light brown color. In my opinion, the cooler does not look too bad it’s doable if you are not into the whole design an aesthetics thing.

The hardware side of this cooler is much more impressive than its design. So this cooler features a dual tower design which means that there are two air cooling fans on this cooler both of 140mm. In the center of these two fans is the aluminum heat sink which has 6 heat pipes going through them. These heat pipes are also made from copper to better capture heat from the base of the cooler. The cooler also comes in black chroma color if you are not a fan of this color.

Best Value Cooler for I9 11900K

Corsair is already known to make some of the best products in the market for PCs which is why I decided to put their most expensive cooler on this list. This Liquid AIO cooler is a complete all-in-one product for both high performance and aesthetic users.

It has 33 bright color LEDs embedded into its centrifugal pump. The RGB lighting glows more with a black overall look of the cooler. There is also RGB included in the fans mounted on the radiator. The pump looks can also be changed with its two separate caps that can be changed easily so you can select which one you like the most.

The cooler introduces 3 high PWM fans of 120mm which makes a total size of 360mm so you need a big case to mount this cooler. These fans bring down your temperatures to as lows as 65 C even when you are using the CPU in a full load.

The pump of this cooler uses a split flow copper cold plate instead of regular copper so it can be more efficient in taking the heat. Unlike other coolers, this cooler pump also outputs a low level of noise.

Connected to this pump are your two tubes made of high fidelity rubber material so when it’s bent it does not block the cooling liquid from traveling. The cooler is super easy to install and is compatible with both Intel and AMD CPUs.
