BEST 240mm AIO CPU Coolers In 2023 [Hands-On]

Here are the Best 240mm AIO CPU Coolers In 2023; filtered by Design, RGB, Budget, White Color, and comparisons with 360mm plus 280mm.

With the evolution of technology, there is a greater desire for better cooling solutions, and now that AIO coolers are on the market, customers are in for a treat. Prior to the reign of AIO coolers, we had Air Coolers, who served us well for a long time, but every King gets dethroned at some point, and Air Coolers were no exception. The introduction of AIO (All In One) coolers has had tremendous influence, but it has also confused customers.

AIO coolers are available in a variety of sizes, ranging from 120mm radiators to 420mm radiators. The fan housing is what differentiates them in size. Some radiators, such as the 120mm, can only accommodate one fan, whilst others, such as the 360mm, can accommodate up to three fans.

People tend to become confused when faced with a variety of alternatives, which is why we’ve compiled a list of the Best 240mm AIO coolers on the market. Take a glance at our picks here:

Weight: 2760 g |  Radiator Dimension: 279x124x30 mm |  Radiator Material: Copper | Tube length: 400 mm | Pump Speed: 2600 RPM (+/- 10%) | RGB: Yes

Pros

  • Copper Radiator
  • Great RGB

Cons

  • Fans can get loud

If you’re looking for a High Performance 240mm AIO Cooler that’s compatible with all DIY water cooling components and can handle today’s most powerful CPUs, go no further. Because we’re bringing you the Alphacool Eisbaer Pro Aurora 240 CPU AIO

To address the issue of cooling extremely large CPU dies, Alphacool designed the Eisbaer Pro Aurora as an all-in-one (AIO) water cooler. The surface area of the cooling fins is 55 x 42mm, which is larger than the size of any processor core currently available. In a nutshell, this basically means that the CPU will be properly cooled due to complete contact with the cooler.

Moving on, the optimal spacing between the cooling fins is 0.4mm, as is the thickness of the fins. In total, you get 58 cooling fins which cover the cooler’s bottom. Talking about the cooler’s bottom, it is only 3mm thick, so any extra heat is quickly transferred into the water and effectively dissipated.

In terms of quality, the CPU block and pump’s weight and solid feel indicate that they are made of high-quality materials, such as thick cast walls for the pump housing and a copper base.

Now let’s talk about the radiator. AlphaCool has used a radiator from its NexXxos ST30 series, which offers effective heat dispersion by using brass and copper for high density. Furthermore, Alphacool is the first company to use just copper for water-bearing parts, such as cooling fins, antechambers, and the cooling channels to which the fins are connected.

To ensure durability, Alphacool used Brass threads in the connections. Since coating the cooling fins with a thick lacquer layer would impair their cooling capabilities, they are painted with a very thin coating.

The cooler has a fin density of 15FPI, which is quite ideal as it ensures that the radiator can do its job despite having poor airflow.

Focusing on the fans, you get 2x Aurora Rise fans which have a maximum speed of 2500RPM. These fans use a custom 3-pin RGB control cable to connect to the lightning module. Plus, it’s good to see that all the LEDs of the cooler are addressable digital RGB.

What We Disliked

When the temperatures begin to climb up, the fans, obviously, will ramp up as well. However, we believe that the noise they make is rather loud, especially when compared to other fans currently in the market.

Verdict

Overall, if you’re looking for a 240mm AIO cooler that does the job well without breaking a sweat, then the Alphacool Eisbaer Pro Aurora 240 CPU AIO should be your cooler of choice. Its high-quality, durable components make it one of the best 240mm AIO to be ever produced, and that’s why we have chosen it as the Best High Performance 240mm AIO Cooler.

EKWB’s new AIO 240 D-RGB liquid cooler delivers exceptional thermal performance and attractive A-RGB lighting effects for a stylish display for 126 dollars, which is somewhat more than other available 240mm AIOs, but understandable. Furthermore, it is one of the few AIOs that is simple to install and configure.

What do we dislike about the EK 240mm AIO?

Despite its premium build quality and superior cooling capability, it lacks software control out of the box, likely to be a big deterrent for many customers. That functionality would require an additional $60 to be unlocked.

Verdict

The EK AIO 240mm D-RGB is a premium liquid cooler providing excellent cooling capabilities and gorgeous A-RGB Pump AIO and Fans. Coupled with its exceptional cooling performance, EK AIO 240mm D-RGB is our choice for the Runner-Up For Best High Performance 240mm AIO Cooler.

What Is An AIO CPU Cooler?

An AIO (All-in-One) CPU Cooler uses a pump/water block, radiators, and fans to cool down your CPU. It works on the same principle as a liquid cooler, but it is easier to install, requires little maintenance, and offers better and quieter cooling than air coolers. In an AIO CPU Cooler, coolant gathers heat from the CPU and then transfers it to the radiator where it is dissipated by the fans. Because of their beautiful looks, easy maintenance, and remarkable performance, AIOs are liked by enthusiasts and gamers all over the world. 

240mm vs 280mm vs 360mm AIO

AIO 240mm 280mm 360mm
Fan Support 2x 120mm 2x 140mm 3x 120mm
Performance Lowest Performance among the three Better than 240mm but worse than 360mm Best performance among the three
Noise Highest noise output among the three Average noise output Lowest noise output

Choosing among various AIOs can be a challenge; each comes with different sizing and pricing. When speaking of dual-fan AIO radiators, you can choose between 240mm and 280mm AIOs. The 240mm radiator can house two 120mm fans, while the 280mm can house up to two 140mm fans. Make sure to also read our article on the Best 280mm AIO for suitable information on a different dimension.

One might think that an increment of just 20mm won’t make any difference, but that isn’t the Case. It does make a difference, so much so that a regular 280mm AIO will perform better than a high-end 240mm AIO because of its larger size. Larger fans mean more airflow and, thus, better cooling. Additionally, due to slower rotation, less noise is produced.

360mm AIO, however, is in a league of its own. The 360mm AIO can house an additional fan compared to the 240mm and 280mm AIOs. Visually, the 360mm AIO differs the most from the rest.

It should now be pretty evident that with increasing surface area, the airflow increases, which means better cooling. Because of its much wider surface area, the 360mm AIO will always be a better cooling solution. The fans wouldn’t have to work hard to keep the temps down, thus running at a lower rpm and producing less noise.

So, the choice is clear when deciding between 240mm, 280mm, and 360mm AIOs. However, the 360mm AIO isn’t ideal. Anything above 280mm counts as an ‘overkill’ unless you are going for some heavy overclocking. Moreover, to house such an enormous radiator, the chassis itself must be massive. The 360mm AIOs are also quite expensive in comparison to the rest.

120mm vs 240mm AIO

AIO 120mm 240mm
Fan Support 1x 120mm 2x 120mm
Performance Not as good as 240mm Better than 120mm
Noise High noise output Low noise output

The name suggests that the 120mm radiator can only house a 120mm fan, while the 240mm radiator can house two 120mm fans. The 240mm radiator, with almost double the surface area of the 120mm radiator, can provide superior cooling, and that too with little noise.

The fan on a 120mm radiator has to work hard to keep the temperatures in check, thus producing considerable noise, while the 240mm fans can perform a better job with the fans spinning slower.

The choice between 120mm and 240mm AIOs should be clear now. 240mm AIO is an ideal choice that can keep your CPU temperatures in check and can fit in almost every chassis. Although it might be expensive compared to a 120mm AIO, it is well worth it.

240mm AIO vs Air Cooler

Cooler 240mm AIO Air Cooler
Fan Support 2x 120mm Depends on the size
Performance Mostly better than air coolers Generally, they are not as good as AIOs
Noise Quiet operations Loud operations

Air coolers have been the norm for a long time and continue to be so, but to a lesser extent now. Liquid Cooling has taken the lead; it is superior to Air Cooling in multiple aspects and is thus widely used instead.

Air Coolers use copper pipes with an integrated heat sink with fans attached, while AIO Coolers have two parts: a Pump connected to the Processor and a Radiator. Air Coolers are cheaper in comparison to AIO Coolers. However, they are bulky and have considerable weight.

However, AIO Cooler is still a better option; why is that? Because it is a better cooling solution. Not only does it have superior cooling capabilities, but it is also better aesthetically. Moreover, it is much quieter in comparison to an Air Cooler.

Cases That Support 240mm Radiator

Before purchasing an AIO Cooler with a 240mm Radiator, be sure if it will fit in your Case. This question can be answered by consulting the user manual for your Case; it should include all the details regarding compatibility, or you can verify it on the manufacturer’s website for your casing.

In addition to ensuring compatibility, you should compare the radiator width to the clearance provided by your Case; the radiator width should fall within the clearance range.

The same is true if you build your PC from the ground up. There will be several options accessible to you that can accommodate a 240mm radiator; thus, it is up to the user to select which cases to select. Some people prefer clean designs with no RGB, while others prefer a full-on RGB configuration.
