Our Favorite AIO Liquid Coolers in 2023

The MSI MEG CoreLiquidS360 is good and reliable for home and work environments and is packed with the latest features. The cooler integrates coveted Silent Gale P12 fans engineered with full silence in mind to give you a cool, comfortable working space. It also comes with a pump embedded in the radiator that keeps everything clustered and keeps noise and vibrations down.

The cooler is quite effective in its cooling performance, a feature made possible by its powerful 2,000RPM. The 60mm fan placed within the water block disperses heat for the M.2 solid-state drive (SSD) and the surrounding components, too. The cooler's MSI Centre adjusts key features like fan speed and Addressable RGB (ARGB) lighting to the in-plane switching (IPS) display to ensure total control in your hands.

A 2.4-inch IPS display screen allows you to observe a wide range of hardware information and customizable graphics. This cooler is simple to install, giving you an easy time setting up your system.

The EK Nucleus CR240 is a welcome improvement on EKWB's Basic AIO in every sense of the word, right down to the EK-branded badge. It even carried over its universally compatible water bloc, which works with the latest AMD5 and LGA 1700 sockets.

Regardless of your allegiance, the EK Nucleus CR240 is incredibly straightforward to install. It helps that the manual itself is well-written, the AIO's design is user-friendly, and all the components are labeled, So even if you're new to PC building, you won't run into much trouble. EKWB even includes pre-applied thermal paste.

Once installed, the EK Nucleus CR240 gets right to business. To previous EK Basic owners, the EK Vardar fans are completely outclassed by the CR240's FPT fans. Using a full-frame design, which helps plug up escaping air, the two 120mm fans have a much more consistent airflow and overall better cooling for the 240mm radiator.

Compact, aesthetically pleasing, and efficient—the Corsair H60x RGB Elite 120mm AIO hits all three with ease, which is to be expected given the brand. Corsair knows its stuff, so if you're looking for an AIO that's going to keep your tiny build nice and cool, it's tough to find anything better for the same price.

The Corsair H60x RGB Elite AIO runs a 27mm-thick radiator, providing plenty of heat dispersion without pushing the limits of your case. The fan itself is 25mm with a max RPM of 1500 and max airflow of 47.73CFM, all of which create a solid cooling system that's well worth the move if you're ditching a stock fan cooler.

Best of all, you've got a lot of wiggle room when it comes to compatibility. The Corsair H60x RGB Elite 120mm AIO supports the latest AMD and Intel CPU sockets, AM5 and LGA 1700, respectively. As a bonus, the RGB on the copper block and fan are pretty snazzy.

Not only does the Arctic Liquid Freezer II 280 have maintenance-free features, but it also has an efficient power consumption rate, making it one of the best AIO coolers for PCs. It comes with a water loop that is sealed and with high-quality fiber-reinforced ethylene propylene diene monomer (EPDM) tubing, so you don’t have to worry about refills.

It lets you get more cooling power to your PC while consuming 80 percent less power, unlike other pumps that run at full load even while idle. This is made possible by automated clocking down of the pumps, thus consuming less power. It also has a more efficient cool plate and radiator that make a difference compared to other AIO water fan coolers.

The machine also includes a 15-degree lower voltage regulator because an additional 40mm voltage regulator module (VRM) fan provides extra cooling for the base and voltage transformer. The cooler also has less cable mess because you're dealing with only one visible cord.

The DeepCool Gammaxx L240 earns a top spot among the best AIO coolers as it offers a highly effective cooling system. This cooler brings an Anti-Leak Tech System that provides an automated pressure balance, which tremendously increases cooling capability. It also supports motherboards with four-pin 12V control, making it easily compatible with various types of CPUs.

The brand-new integrated 12V RGB lighting system is a handy feature that supports traditional motherboards with synchronized lighting control. With six ultra-bright RGB LED lights and RGB effects that come built-in, this cooler provides steady light. Besides illumination, it also comes with meteorism and PWM control features that ensure smooth and quiet performance.

From a fan perspective, the DeepCool Gammaxx L240 does not disappoint, with its two 12mm fans made out of translucent blades. This gives the cooler a 2,550 RPM with the help of the aluminum radiator that connects to the pump.

A little RGB is fine, but what about a personal touch? If you’re someone who obsesses over customization, the NZXT Kraken Elite 280 Liquid Cooler offers the best of both worlds: a high-performance pump and personalization.

Built onto the aluminum block itself is a rather large LCD display with a resolution of 640x640. It’s a sharp screen, which means anything you choose to display—system information, CPU temp, GIFs, or images—is going to look great.

Of course, the NZXT Kraken Elite 280 is also built for performance and durability. The tubes are reinforced with nylon braids, but more importantly, can push up to 2800RPM. It pairs wonderfully with the two large 140mm fans that have a maximum airflow of 99.68CFM. The cherry on top is that it never gets louder than a whisper!

While aesthetics don't offer any benefit in terms of performance, there's something special about highlighting the best components in your rig with a splash of color. Well, in the case of the Cooler Master MasterLiquid PL240, you're splashing a lot of color.

The Cooler Master MasterLiquid PL240 highlights both the fans and the pump block with gaudy RGB lighting, which you're welcome to customize. In fact, if you're short a connector, you can use the USB-powered manual controller Cooler Master was gracious enough to include in the packaging.

It's all meant to highlight the stars of the show: the 120mm SickleFlow fans and the pump. What's special about the fans is how the Cooler Master MasterLiquid PL240 uses a combination of interconnected fan blade rims and beveling to improve airflow. In other words, when you push your rig, the fans are going to be far better at consistently cooling the radiator.

Finding the Best AIO Cooler For Your PC

The MSI MEG CoreLiquid S360 Cooler is a tough AIO to top. With three high-speed fans, a handy IPS display, and coverage, the S360 has it all. What is especially compelling is its ability to cool nearby components, too. While the VRM and M.2 SSD don't contribute loads of heat, it doesn't hurt to keep the overall temperature of your PC down a few notches.

But, you don't have to worry too much about neighboring components if you're stuck with a tight budget. For more bang for your buck, you want the EK Nucleus CR240, especially if you're new to PC building and AIOs in general. You're getting plenty of airflow, cooling, and both AMD and Intel CPUs are welcome. The rotatable pump top is also a nice touch if you happen to install the cooling block upside down.
