7 Best All In One Liquid Coolers to Buy in 2019 — Keep Those Temperatures Under Control

By Vaidyanathan Subramaniam / November 11, 2019

We've seen some of the best CPUs and motherboards across Intel and AMD platforms and these components require the best cooling solutions for peak performance. All AMD CPUs come with a stock air cooler that should suffice for most applications whereas Intel does not offer any stock cooler on its enthusiast processors. Even if AMD processors come with fairly capable coolers, you may find it worthwhile to invest in an aftermarket cooling solution if you are looking at overclocking or running heavy loads on the processor.

All in one (AIO) liquid coolers offer a great solution for those looking at a robust CPU cooling solution that does not have high noise emissions. An AIO liquid cooler basically consists of a CPU block and pump combo that sits on the integrated heat spreader of the CPU and a radiator with one or more fans to dissipate the heat. The pump circulates a coolant that helps draw the heat away from the CPU.

AIO liquid coolers are available from a number of quality brands. We list the 7 best AIO liquid coolers that you can buy in 2019 to help keep your processor cool while you are busy fragging your enemies.

1. NZXT Kraken M22

The NZXT Kraken M22 is a compact AIO liquid cooler for your new high-end Intel or AMD CPU. The Kraken M22 has a very simple design and comes with just a pump and a single radiator fan. The pump has RGB effects while the radiator does not. Apart from the Threadripper series, the Kraken M22 supports all modern CPU sockets from Intel and AMD. The pump is mated with an NZXT 120 mm fan rated at 2000 RPM. The RGB lighting on the pump can be controlled by a 9-pin cable that connects to the USB header on the motherboard. NZXT provides the CAM software to monitor the performance of the AIO liquid cooler. The CAM software offers a reasonably detailed readout of various pump and temperature parameters apart from other system components such as GPU and RAM. The software also allows controlling the RGB effects on the pump. The CAM software is not needed for the pump to function and users who are on the fence about the software sending the data to NZXT's cloud servers can choose to skip installing it. The CPU heat spreader contact is made of milled copper and comes pre-applied with a thermal compound.

The NZXT Kraken M22 comes with only a single radiator making it an ideal choice for compact HTPCs. The cooler is well-designed and does not obstruct the wiring or placement of other system components. The performance of the Kraken M22 is excellent for its size with extremely quiet fan speeds.
