Best AIO Coolers


Cooling solutions have been a vital component of a gaming rig for the past decade, and now more and more people are paying attention to it. Most of the processors these days allow overclocking, which raises heat dissipation, which is why aftermarket coolers are a thing. The all-in-one cooling solutions have received special treatment compared to air coolers due to their pleasing aesthetics, and most enthusiasts prefer buying an AIO cooler instead of a bulky air cooler.

Some years ago, NZXT, CORSAIR, and COOLER MASTER were the only companies that manufactured AIO coolers. Still, as of now, there are lots of high-end companies that are trying to provide uniquely designed AIO coolers. Most of the modern AIO coolers come with RGB lighting and greatly enhance the overall appeal of the gaming rig. In this article, we will be looking at some of the best AIO coolers ever designed.

Quick Buying Tips!

Buying an AIO cooler can be a daunting task, and that is why we have come up with a buying guide that will help you buy a suitable AIO cooler for your gaming rig.

Radiator Size: The most crucial factor of an AIO cooler is the radiator size. The larger the size of the radiator will be, the better the cooling will be. The most common radiator sizes are 120 mm, 140 mm, 240 mm, 280 mm, and 360 mm. The 120 and 140 mm radiators are usually used in budget AIO coolers, while most high-end coolers use either 280 mm or 360 mm radiators.

Fan Performance: It might not seem like this, but fans of a cooling solution play a significant role in its operation. The latest technologies associated with fans allow them to perform with lesser noise and modern fans have higher airflow and static air pressure.

Reliability: Liquid cooling solutions can turn into disasters very quickly, and that is why many people are afraid of using them in their systems. However, modern technologies have increased the reliability of the AIO coolers, and they now come with various sealing technologies, etc.

Corsair H100i RGB PRO XT

Best Budget AIO Cooler

CORSAIR designs some of the best AIO coolers globally and has a long history of doing so. CORSAIR H100i RGB PRO XT is the mainstream AIO cooler by the company that is available at a mediocre price. It is a 240mm AIO cooler, i.e., it is not the largest AIO cooler by the company, but still, its performance is quite close to 360mm AIO coolers. 

CORSAIR H100i RGB PRO XT cooler, as the name indicates, has RGB lighting on the pump. The lighting can be customized through the CORSAIR iCue software application and is known to be one of the best applications for RGB customization. The CORSAIR logo at the center is RGB-lit as well.

The company has used its latest Magnetic Levitation series fans in this cooler. These ML series fans are great for high static air pressure, and the noise levels are around 37 dB during operation. The fans do not have RGB lighting on them, which you can find in the Elite Capellix series cooler by the company. The cooler has Zero RPM mode as well, which makes it go completely silent when the thermals are under control.

As for the compatibility of this AIO cooler, it supports Intel LGA 1150 / LGA 1151 / LGA 1155 / LGA 1156 / LGA 1366 / LGA 2011 / LGA 2011 3 / LGA 2066 and AMD AM2 / AM3 / AM4 / FM1 / FM2 sockets.

Alphacool Eisbaer Aurora

Best Looking AIO Cooler

Alphacool Eisbaer Aurora seems to be a great alternative to the CORSAIR H100i RGB PRO XT when you want to focus more on the looks of your rig than the raw performance. This company is, although not as much famous as the likes of CORSAIR, you don’t need to worry about the reliability of its AIO cooling solutions. 

Alphacool Eisbaer Aurora is a 240 mm AIO cooler that comes with RGB lighting on the pump and the fans. In fact, the fans have aRGB lighting on them, which looks way more incredible than the ML series fans by CORSAIR. The company has used TPV hoses and fittings from the Enterprise Solution series, which is why you don’t need to worry about the risks involved with leaks, etc.

The pump of this liquid cooler is not as well designed as the CORSAIR H100i RGB PRO XT, but that is the only con that can be considered against the CORSAIR cooler. The performance of this cooler is slightly lower than the CORSAIR H100i RGB PRO XT, but if you are not into extreme overclocking, this should not be much of an issue. The fans have an RPM range of 800 to 2000 RPM and have a static air pressure of 2.0 mm H2O. 

The cooler supports Intel LGA 775 / LGA 1056 / LGA 1155 / LGA 1150 / LGA 1151 / LGA 2011 / LGA 2011-3 / LGA 2066 and AMD AM2 / AM2+ / AM3 / AM3+ / FM1 / FM2 / FM2+ / AM4 sockets.

DEEPCOOL Captain 240 PRO V2

Best 240mm AIO Cooler

DEEPCOOL is becoming a major company that designs liquid cooling solutions. Its Captain and Castle series RGB coolers gained a lot of popularity due to unique looks, and today we are looking at DEEPCOOL Captain 240 PRO V2. It is also a 240 mm AIO cooler, but it looks better than both of the previous coolers due to its better RGB lighting. 

First of all, there is RGB lighting on the cooler fans, and since they have a milky color, the illumination shines on them very nicely. Other than that, the design of the pump of this cooler is unique. There is a thick U-shaped steel pipe coming out of the pump, which gives it a complex look, while the RGB lighting is present at the top of the pump and its sides.

Deepcool’s exclusive Anti-leak Technology allows it to be much better than most other AIO coolers in the market, giving it a better reliability score than other coolers. The performance of this cooler is similar to the Alphacool Eisbaer Aurora, lying slightly below the CORSAIR H100i RGB PRO XT. The fans of this cooler have an RPM range of 500 to 1800, while the static air pressure of fans is 2.42 mm H2O.

The cooler supports Intel LGA 2066 / 2011-v3 / 2011 / 1200 / 1151 / 1150 / 1155 / 1366 and AMD TR4 / AM4 / AM3+ / AM3 / AM2+ / AM2 / FM2+ / FM2 / FM1 sockets.

Best Appealing AIO Cooler

NZXT is a company that focuses a lot on aesthetics, and that is why most streamers prefer buying their products. NZXT Kraken X53 is a budget cooler by the company that is available at a lower price than the CORSAIR H100i PRO XT, yet having better looks.

The non-RGB cooler still offers RGB lighting on the pump. The circular pump has beautiful RGB rings in it, providing a fantastic view to the user. Apart from that, the NZXT logo at the center is RGB-lit as well. 

The cooler uses Aer P 120mm fans, and these fans are less powerful than the CORSAIR ML series fans, which is why the performance of this cooler is lower than that of the CORSAIR H100i PRO XT or even the Alphacool Eisbaer Aurora. The fans have an RPM range of 500 – 2,000, similar to other fans on the list, while its static air pressure is around 2.93 mm H2O.

Frequently Asked Questions

Are AIO coolers better than air coolers in cooling?

It is not necessarily true that an AIO cooler outperforms an air cooler, especially a dual-tower air cooler. However, most high-end AIO coolers perform better than high-end air coolers and are better suited for overclocking.

Are AIO coolers less noisy than air coolers?

Although it seems like AIO coolers would be less noisy than air coolers, this is not true all the time. AIO coolers have many fans attached to their radiators, and the pump of the AIO cooler also makes noise, which is why the noise levels of AIO coolers sometimes surpass that of high-end air coolers.

What is the primary advantage of an AIO cooler compared to an air cooler?

The most significant advantage of an AIO cooler is that the pump has a tiny footprint and the motherboard does not stay hidden behind it, which is why the whole setup looks way better. The average performance of an AIO cooler is considerably better than an average air cooler as well.
