Best CPU Coolers for the i9 10900K

In the end, a 240mm AIO cooler is the best and most balanced option for the i9 10900K. As a result, here are our top picks for the best 240mm cooler for the i9 10900K.

Arctic Liquid Freezer II is the sequel to the Arctic Liquid Freezer.



  • Fans that spin at 1800 RPM
  • Pipes with sleeves
  • Water block with a stylish design

The Arctic Liquid Freezer II is at the top of the list. A multi-compatible AIO CPU cooler with approximately 5 distinct versions, with the 240mm model being our favorite. The Arctic Liquid Freezer is well-known in the industry for its extremely efficient and well-carved All-in-one design. Two 120mm fans are linked to a small water pump through completely sleeved tubes in the 240mm version. The Arctic Liquid Freezer II is one of the company’s finest innovations, and it has proved its value as a balanced cooler with good thermal performance and a low noise level.

The in-house designed PWM-controlled pump is one of the most amazing improvements in this CPU cooler. This small pump has a copper foundation for superior thermal performance and efficiency, as well as a low power consumption and low noise level. PWM is a well-known and well-appreciated phenomena in fans, but it’s even better in pumps; with Liquid Freezer II, your pump won’t be operating at full load when it’s not in use. Instead, it will clock down, making it not just quieter but also using much less energy. And, in addition to all of this, there is a 40mm fan next to the pump to keep the VRM chips cool, which is a huge assist, particularly if you intend to overclock, and causes no noise. Another icing on the cake is the sealed water loop, which is maintenance-free and doesn’t need any water or additive replenishment, elevating convenience and ease-of-use to new heights. 

The two P-Fans are also among the best in the business. These P-Fans are further improved with high static pressure for better cooling performance, with a good RPM range of 200 – 1800 that uses less power and produces less noise overall. The high-quality bearings also contribute to better performance and a longer lifetime. The fans are also synced with the pump for PWM, so they both clock down when not in use, saving energy and maintaining a quieter operation. 

Overall, the design is extremely clean and appealing. It is well-designed and therefore manageable; in particular, the completely sleeved tubes help with cable management. The fans are neatly positioned above the completely enclosed radiator, and the water pump has a distinctive design that looks great on display. This water pump comes with a lot of features and is a fantastic option for the finest 240mm cooler for the i9 10900K.

  • High-quality construction
  • Airflow that is quiet

Another 240mm All-in-one CPU cooler for the Core i9 10900K is the EVGA CLC 240mm. The EVGA CLC 240 Liquid cooler offers efficient cooling performance at a low noise level, as well as fast software control for customization. This All-in-One cooler has a nearly identical technological design as the Arctic Liquid Freezer II, with the exception that it has a much more simplistic appearance and performance that is almost identical to the Arctic Liquid Freezer II. It comprises of two 120mm fans linked to a thin radiator with two completely sleeved tubes connecting it to the pump head. For a high-demanding PC like the i9 10900k, the cooling performance is sufficient, if not superior in certain instances.

EVGA’s two 120mm fans are a brand-new design. The fans’ curved housing greatly improves airflow and reduces noise by minimizing vibration, while the unique blade design enhances cooling performance, which is already very competent with an amazing speed of 500-2400 RPM. The Teflon Nano bearing takes things to the next level by ensuring a smooth operation with little noise while also extending the fan’s overall lifetime. One of the most useful features is that the EVGA program allows you to adjust the fan speed and curve. The tubing connecting the radiator block underneath the fans to the pump head is completely sleeved, and every other wire is smartly handled, resulting in a tidy cable management system. 

In comparison to earlier EVGA advancements, the pump head now features a brilliantly gleaming and visible EVGA logo on top. The redesigned block has a higher flow rate and a larger heat transfer surface area, allowing for more cooling capacity. This pump head is also maintenance-free, which is a big plus in terms of convenience since you won’t have to worry about filling or refilling it. The copper foundation allows for optimum heat dissipation, resulting in enhanced performance. The RGB LED on the pump head may be controlled completely through software. You may also create your own unique profile, which will be stored in the firmware. 

The EVGA CLC 240 has a traditional and straightforward design. As a result, in the minimalist’s instance, it seems fine and beautiful. The RGB is very straightforward and looks great on screen. The EVGA program provides amazing control and makes the process a whole lot simpler. EVGA goes on to say that the fans will last 80,000 hours in total, which is pretty impressive given the 5-year manufacturer’s guarantee. The pricing is fair for almost identical performance as the Arctic Liquid Freezer II, and it performs well for the i9 10900k.

The Core Liquid 240R is another great option for entry-level gaming fans looking for a 240mm AIO CPU cooler that can handle any other demanding program. It comprises of two 120 fans with cutting-edge housing designs, which are linked to a compact radiator, which is then connected to a 270-degree rotatable and beautiful pump head through three layers of netted plastic tubing and a reinforced mesh exterior.

The two 120mm fans spin at a reasonable speed of 500–2000 RPM and are very silent. When the cooler is not under a lot of stress, you may use the PWM mode to enjoy an even quieter experience. The ARGB LEDs provide a beautiful display of color; it’s also compatible with Mystic light, allowing you to customize and sync it with other components for a fantastic side-glass show. MSI has improved the radiator in several ways to enhance cooling efficiency, including the radiator pump design, which incorporates a pump inside the radiator for sound damping and noise reduction. This also provides a safe area for the pump away from the heating source, resulting in a longer pump lifetime. The heart of the pump, a long-lasting three-phase motor, generates low vibrations for long-term operation.

The radiator has also been built with a divided route running through it, which will aid in the fast dissipation of heat and improve the cooling process.

The radiator is linked to the 270-degree rotatable heat pump through three layers of netted plastic tubing with a reinforced mesh exterior that prevents evaporation. The circular-shaped pump head has a triangular design with an MSI dragon emblem on it and can rotate 270 degrees in any direction. New users will find mounting and installation to be simple. The pump head also has beautiful ARGB lighting that complements the LEDs on the fan.
