Traditional heatsink and fan CPU coolers are fantastic for keeping your desktop processors operating within an optimal temperature range. Still, if you want to do some overclocking and stress the CPU, you'll need to invest in more complicated water cooling. Luckily, there is some fantastic all-in-one (AIO) kits from reputable brands that are simply plug-and-play. The NZXT Kraken M22 (opens in new tab) gets the job done, but so do the other options on this list. Take a look!

Stunning visuals

The Z63 is NZXT's latest take on all-in-one coolers and is the smaller sibling to the Z73 with but a 240mm radiator. Still, it's incredibly powerful and can keep even enthusiast CPUs cool under load, but the highlight feature is the LCD display, which can show temperatures, animated images, and more.

NZXT Kraken M22 (opens in new tab)

Beastly cooler

Like the Z63, this AIO could win out on the name alone, but it also performs well. The M22 packs a lightweight 120mm radiator and barely weighs anything. Throw in included support for the NZXT Hue lighting system and its CAM software for digital fan control, and what you have is a cooler that will perform well and look good in your custom PC, all for a reasonable price.

Thermaltake WATER 3.0 (opens in new tab)

Smart cooling

The WATER 3.0 from Thermaltake features the company's latest innovative Riing fans with a self-contained controller. The RGB lighting is integrated into the actual casing of each fan, as opposed to mere LED bulbs scattered around the surface, which makes for a continuous beam of light that shines throughout the case. With up to 360mm of the radiator surface, a high-quality pump, and an efficient copper base for optimal heat transfer from the CPU, the WATER 3.0 is designed to keep even the more power-hungry processors well within safe operating temperature ranges, especially when under load and overclocked.

Cooler Master MasterLiquid ML360R (opens in new tab)

Serious performance

Cooler Master not only created an AIO that looks sleek and ready for an exquisite build but also included some serious headroom. You'll have no problem overclocking your CPU with the 360mm radiator setup, and there are more RGB lights than you'll know what to do with. The lighting on the ML360R can be configured through the MasterPlus+ software suite.

DEEPCOOL Captain 240PRO (opens in new tab)

Silent pumps

DEEPCOOL produces some killer hardware, and the Captain 240RPO is a great example, featuring a 240mm radiator, efficient fans, and a silent but powerful pump. You'll be able to push your system to the limits with this setup. This cooler also supports external management software through the use of a cable, which can be hooked up to your motherboard. It's perfect if you already make use of your own RGB lighting.

How do you choose an AIO?

Deciding what AIO to choose can prove a little daunting since most of them appear to be the same. If you need a small 120mm radiator AIO for your CPU and already have adequate case airflow, the NZXT Kraken M22 (opens in new tab) will be more than capable of handling even some moderate overclocking. NZXT offers different Kraken models, depending on your requirements. 

When you have a powerful, multi-core processor that's kicking out some serious heat, you'll need to step it up with another cooling solution. Should the different Kraken models not be what you're looking for, Corsair's H100i Elite LCD is an excellent secondary pick. It has incredible performance, customizable lighting, and is available in three different sizes.
