Roll up for the best ASUS coolers money can buy! Liquid cooling is increasingly popular among PC enthusiasts and there’s a growing number of products being produced by different brands to cater for these needs. Typically this is focused on the cooling for the CPU and takes the form of an All-In-One (AIO) setup that includes a pump, radiator, and fans within a single unit. Below we’ll be discussing the options offered by ASUS, one of the leading brands in the market.

If you’re new to AIO setups, you can read our how to install liquid cooling guide, which will walk you through the process in easy to understand steps. ASUS also has their own all-in-one liquid cooling guide which you can consult to get more information on their different product lines; their ‘comprehensive compatibility’ table is particularly useful on this page if you want to make absolutely sure that a particular cooler matches your chosen motherboard socket. Finally, do also read our ‘what to look for when buying an AIO cooler?’ section further down this page if you need to brush up on your knowledge before pulling the trigger on a purchase.

Are ASUS AIO coolers any good?

ASUS are known for producing some of the most high-end AIO coolers available, which regularly appear in our ‘best CPU cooler’ lists each year. They mostly produce premium grade products though they do have more affordable options within the TUF range as well. Most ASUS liquid coolers come with a 6 year warranty, which should bring you some comfort as to the quality of these products.

The ProArt LC 420 is design suited to content creators and workstation users and the like who aren’t interested in distracting RGB, and want something a bit more stealthy. It’s available in just this one black color and in 420mm size only, which is large indeed.

Noctua are a premium fan brand favoured by enthusiasts, known for being powerful, yet quiet, and the three 140mm NF-A14 fans the cooler comes equipped with are top notch. The fans will only reach about 31.5db when put under strain and yet are capable of shifting 4.18mmH20 of fan air pressure. The radiator they’re housed in is extra thick to provide a greater surface area and therefore improved cooling.

Besides this you get an illuminated meter which displays system information, plus extra reinforced tubing to ensure superior durability.

What to look for when buying an AIO cooler?

Compatibility with the CPU and motherboard

When picking a cooler, the first thing to do is look at what TDP value it supports: this represents the Wattage (i.e. power) of the CPU, with higher TDP values requiring more advanced cooling. With regards to motherboard compatibility, you’ll want to match up the sockets supported by the cooler with those of the motherboard.

Factors that determine cooling performance

CPU AIO coolers work by affixing a conductive heatsink to the processor which draws heat away from the component by the movement of liquid through it. Warm liquid is pulled away from the heatsink towards a radiator where the temperature is dissipated outside of your case, the now-cooled liquid travels back to the heatsink where it ‘picks up’ more thermal energy, and the cycle continues. The movement of the water is controlled by a pump which is usually affixed to the heatsink forming what is commonly referred to as a ‘water block’. This is connected by tubes to the radiator, which works by forcing the warm liquid into thin tubes in a high-surface area mesh through which fans blow air.

The three main factors that determine the effectiveness of an AIO cooler then are the heatsink, the water pump, and the radiator.

Noise levels

On average, AIO setups tend to be a bit quieter than air cooling builds, particularly under heavy strain, though this is not always the case. As mentioned above, liquid cooling setups do still incorporate fans in order to extract heat from the radiator and out of your case which do make a noise, and the water pump itself also makes a noise; how quiet an AIO is can vary depending on the manufacturing of these two features.

Reliability

Given these AIO systems will be pumping liquid around the electrics of your highly valuable computer, reliability is of the utmost importance. Assuming you put the tubing together correctly, it tends to be the pump which can cause any leaking issues, so we advise doing a bit of reading to make sure this is of an acceptable quality. Thankfully ASUS products tend to be of very high build quality.

If there are any issues with your unit, ASUS also offers a 6 year warranty for AIO coolers, which is one of the longer ones out there, with a 1 year warranty for the water block element specifically.
