Best CPU Cooler for i9 12900K

DeepCool Assassin III

Starting with a budget-friendly item we have the DeepCool Assassin III on top of our list as its hits all of the checkmarks of a great CPU cooler. Starting with the build quality and design DeepCool Assassin III takes a simple approach over the design factor.

It doesn’t include any fancy RGB lighting but it has a combination of deep black and chrome which does improve its looks by a lot and make it look more stylish. As for the fans you have two fans with one in the middle to give you that extra cooling effect directly on the CPU both of these fans are 140mm so if you have a smaller case you might need to get a bigger one.

Moving on to the construction of the Cooler you have two aluminum fins that are fitted with a novel thermal module layout so they can act more efficiently and to ease things up you have 7 heat pipes all of which are in prolonged contact with the convex copper base that sits directly on top of the CPU.

These heat pipes can carry more heat towards the heat sink of the cooler so they can be escaped more quickly with the help of two fans. The fans have two layers that can improve the airflow by 2.5m2/min making it the Best CPU Cooler for i9 12900K.

The Assassin II has a relatively easy installing mechanism and it also comes with its custom screws so it can fit perfectly. The good thing about this cooler is its wide range of compatibility as it can also support AMD CPU and other Intel Processors without any additional things required to get it installed.

Arctic Liquid Freezer II 280

Arctic Liquid Freezer II 280 is built with no compromises on cooling and offers more reliability than any other liquid cooler. The company has already achieved a successful name in the business due to the efficiency of their products in working so this time they have stepped up the game with the Liquid Freezer II 280.

This cooler can make a noticeable difference in keeping the CPU much cooler by 15C and that is the reason why it’s the best liquid cooler out there. Moving on to the design aspects you don’t get any RGB lighting on it otherwise it will not be as budget-friendly but you do get an all-deep black color on the whole cooler including the base. This color makes the cooler look more aggressive and sleek in looks.

The liquid freezer II 280 has a more systematic pump, radiator, and cooling base which makes it different than any other coolers out there. As I mentioned earlier that this cooler can make a difference of 15C it’s because it includes a VRM fan of 40nm which if you think is quite smaller but due to its position right next to the pump it does make a difference.

Moving on to the 2 bigger fans of 240mm they can spin at around a maximum of 1700 RPM without producing much noise thanks to their new bearings. One biggest problem that you always have to face with the liquid coolers is their maintenance but thankfully this cooler doesn’t give you that headache because the water loop cables are perfectly sealed with high-quality EPDM tubing. The liquid Freezer II 280 also does not require much power it consumes 80% less power when running idle making it more efficient with little to no noise levels.

Cooler Master ML 360 RGB

We are all aware of the Cooler Master as their products are efficient and long-lasting. Cooler Master products are built to provide the ultimate performance experience according to users' needs. Cooler Master also manufactures ML 360 RGB.

What makes this cooler stand out is its RGB lighting because they are not ordinary RGB lights; you can control, set them according to your tastes, and can also synchronize them with your PC’s lighting. To add more visual appeal to the cooler, the CPU base also has RGB.

Despite the fact that these fans can spin at 2000RPM, they produce a maximum sound level of 30dBA at full speed and 6dBA at idle. Aluminum radiators absorb most of the heat generated by the processor to mount those fans easily.

Regarding CPUs, the cooler’s microchannel base has been polished to sit directly on top of the CPU while allowing water to come into contact with the base, thus allowing greater heat absorption. Two flexible tubing pipes are attached to the cooler, so even when bent to a certain extent, they won’t obstruct water flow. All these features makes it the Best CPU Cooler for i9 12900K.

The fan requires a simple 4-pin connector, whereas the pump uses a 3-pin connector, so you don’t need a large-sized connector for the cooler. In addition, the ML 360 RGB equips with a warranty of up to two years.

Corsair Hydro H150i Pro RGB

Corsair Hydro H150i Pro RGB AIO Liquid cooler maybe a little overpriced for some people but you do gain some advantages.

Noctua NH-D15

If you want something simple looking yet more effective the Noctua NH-D15 is a reliable choice for you. Now some people may not like the design of this cooler but this cooler is designed to be more effective in its performance rather than having a good design and a layout.

Despite having a not-so-good design this cooler still hits all the checkmarks of a premium high-end previous-gen cooler as you see from Corsair or Cooler master or other major brands. This cooler comes with two fans one is mounted on the front and the other is in the middle of two aluminum fins. The fans are in brown whereas the housing of them is in beige. The aluminum fins are in the standard silver color.

The cooler has a dual-tower design meaning that it has a state-of-the-art cooling architecture with 6 heat pipes and two 140mm fans that provide excellent cooling with a max speed of 1500 RPM with a noise level of only 24.6dBA.

These fans can also sense low temperatures and they automatically slow down when needed. The heat pipes are directly in contact with the bottom copper base of the cooler.

This makes the heat pipes carry more heat to be exited and to make things easy these heat pipes then go through the two aluminum heat sinks where they are cooled by the air fans. The cooler also does not take a lot of space and consumes only 12 Volts of power with a 4 pin power connector.

The most impressive part of this cooler is probably the 6-year manufacturer’s warranty. This cooler can also support both Intel and AMD processors and can also include a special mounting kit for older Intel generation processors.

Now despite having a smaller design this cooler still makes sure that you have the ultimate cooling effect on your PC with its new Liquid-cooled pump design but we will cover that later because first let’s talk about the first impressions of the color.

The cooler does not seem cheap it has a very premium feel and comes with an all-black look with the addition of RGB lighting on the fans and the pump.

The radiator has a size of 280mm which means that it houses two 140mm fans. Due to the bigger size of the fans, you don’t need much higher RPMs to get more cooling because there is already more airflow by the fans even when at lower speeds but you can still run these fans at 2000RPMs if you want to have higher speed.

Also, these fans are levitation PWM fans so they are already powerful and produce a low noise level of 36dBA.

Moving on to the liquid pump it also includes a copper base and is connected with the same fidelity pipes as they are much stronger and do not block or slow down the liquid pressure when bent to a certain level.

The H115i includes 33 bright RGB lights so they can be appeared even in brighter areas you can easily customize your fan speed and different profiles with the iCUE software from Corsair and can have full control over the cooler.

The software also includes a zero RPM mode that can automatically stop the fans and use liquid cooling when it detects low temperatures so that you have zero noise levels from the fans.
