Water loop enthusiasts who want to customize their water loops definitely know about EK and its top-quality products. They also offer ready-made solutions like the EK 240mm AIO liquid cooler that made it in our top 6. It’s the most powerful 240mm AIO if RGB is your thing and it’s also the most durable and efficient model.

Solidity is the very first thing you’ll see in this AIO. Pump heads are huge, with an acrylic top, which acts as a light diffuser to all the controllable RGBs inside. Our only complaint with this cooler is the RGB control. Software like RGB Fusion and Polychrome works as intended. However, you can’t access subtle fan curves and color adjustments unless you purchase an additional controller unit.

The plain radiator houses two fans that pull air out powerfully while being designed to shine with magnifying colors. The RPMs range is broad and the CFM is adequate, but not extraordinary. Each fan has the ability to maintain a static pressure close to 3mmH2O, which allows them to function as intended in weird old cases not built with proper airflow. So, the EK AIO 240 is definitely worth a try for you. 

8 Things to Consider Before Buying a 240mm AIO Liquid Cooler

When looking for a 240mm AIO liquid cooler, there are several important factors to consider in order to ensure compatibility and optimal performance. Here we will go over eight of the most important things to keep in mind before making your purchase.

240mm AIO liquid coolers

1. Socket Type

One of the first things to consider is the socket type of your CPU. Most 240mm AIO coolers will be compatible with multiple types of sockets, but it’s always best to check before purchasing. Not all coolers are created equal and some may not work with your particular socket type.

2. TDP Rating

The next thing to consider is the TDP rating of your CPU. The TDP, or Thermal Design Power, is the maximum amount of heat that a CPU can generate. It’s important to choose a cooler with a TDP rating that exceeds that of your CPU. Otherwise, you risk your CPU overheating and sustaining damage.

3. Fan Speed

Another important factor to consider is the fan speed of the cooler. The faster the fan speed, the better cooling performance you can expect. However, higher fan speeds also mean more noise. So, if you are someone who doesn’t like noise while gaming, go for a quiet 240mm AIO cooler.

4. Radiator Size

The size of the radiator is another important consideration. Larger radiators tend to offer better cooling performance but they also take up more space. If you’re working with limited space, be sure to choose a cooler with a smaller radiator.

5. Pump Noise

The pump is responsible for circulating the coolant through the radiator and CPU block. Some pumps are louder than others, so if you are looking for a quiet 240mm AIO cooler, be sure to check the pump noise before making your purchase.

6. Ease of Installation

Installing a 240mm AIO cooler can be a bit tricky, so it’s important to choose one that is easy to install. Some coolers come with detailed instructions while others do not. If you’re not comfortable installing the cooler yourself, be sure to choose one that comes with easy-to-follow instructions.

7. Warranty

All 240mm AIO coolers come with a warranty, but they vary in terms of length and coverage. Many coolers come with one year warranty whereas some brands offer more than 3 years of warranty. So, be sure to check the warranty before making your purchase to ensure that you are getting the best possible coverage.

8. Price

Of course, price is always a consideration when making any purchase. However, it’s important to remember that you get what you pay for when it comes to 240mm AIO coolers. The more expensive models tend to offer better cooling performance and features. If you are on a budget, be sure to justify the prices of several different coolers after making a decent comparison of features.

Frequently Asked Question

Q1. Is AIO Liquid Cooling worth it?

If you’re really looking to go all-out, it’s probably better to use a completely custom water cooling loop. But they’re expensive, complicated, need maintenance, and come with more failure points. AIO liquid coolers are easy to install, maintenance-free, less expensive, and are cool as well.

Q2. Is an AIO Better than an Air Cooler?

The first question that people ask is often: Air or water? Air cooling is typically less expensive and easier to use. The top air coolers are superior to ever before, however they’re quite bulky and high-end AIOs typically surpass their counterparts. The water cooling process is much more effective since water is a superior thermal conductor. This means it’s more efficient at moving energy away from the processor. There is a small chance of leakage, however, this is becoming increasingly uncommon.

Noise levels are largely dependent on the type of fan used. However, an excellent AIO is quieter than an air cooler even during high temperatures.

As for actual cooling performance, there’s nothing in the middle between the best of each, however AIOs tend to be faster in moving from idle to peak temperatures than a conventional air cooler.

Q3. What are some Best 240mm AIO Liquid Coolers Presently?

The best 240mm AIO liquid coolers are:

  1. ARCTIC Liquid Freezer II 240
  2. Corsair iCUE H100i
  3. NZXT Kraken X53
  5. Cooler Master MasterLiquid ML240L V2 Black and White
  6. EK 240mm AIO D-RGB

Q4. What to Look for in a 240mm Liquid Cooler for CPU?

The most significant aspect of any AIO CPU cooler will be its size. A larger radiator provides greater cooling efficiency, however, it is important to ensure that it is able to fit into the case. In other words, you should look into your socket’s support to be sure that you can use the cooler with your motherboard. And make sure to buy from a reliable brand only.

Q5. Do you need to Refill AIO Coolers?

AIO coolers are reliable. AIO coolers have increased significantly and leaks are extremely uncommon. Like all mechanical devices, there is always the chance of a pump failing but modern CPUs come with safeguards when the device becomes overheated. 

In the end, you can use an AIO within your system without worrying about it. Coolers are prone to degrade in time, as coolant slowly evaporates or disappears from the solution, but now manufacturers discover new techniques to make AIO coolers more durable.

Q6. Is Liquid Cooling Reliable?

Liquid cooling is an effective method to cool your CPU since water transfer is more efficient than air. Liquid cooling is quieter than air cooling as there aren’t fans running at high RPMs that make irritating noise.
