Best 240mm Air Cooler Review – Tested 2021

We’ve already looked at the best 360mm and 280mm AIO coolers, and today we’ll look at the best 240mm AIO coolers. Although 240mm AIOs can not provide the same amount of cooling as 360mm and 280mm AIOs, they are still excellent choices for those looking for a better cooling solution.

And we’ve highlighted some of the best 240mm  air cooler AIOs currently available in this guide. We’ve chosen the best overall option, a runner-up, the best 240mm liquid cooling with RGB fans, the best white 240mm AIO, and the cheapest option.

Best 240mm Air Cooler

What is the Best 240mm Air Cooler?

1.Corsair iCUE H100i

The best 240mm AIO CPU cooler

We selected Corsair’s iCUE H100i AIO cooler as our top pick. Two 120mm Corsair ML120 PWM fans with speeds up to 2400 RPM are included with the iCUE H100i. The fans can also go into Zero RPM mode, which entirely shuts them down during low CPU loads. The H100i is also highly silent, thanks to its ability to entirely shut down.

The H100i also has a five-year warranty and supports both AMD and Intel processors. It also has an RGB-lit pump head. The H100i is also one of the better-performing 240mm AIOs on the market in terms of cooling capacity.

The bottom line is that the Corsair iCUE H100i is a decent choice to consider if you’re looking for one of the best 240mm AIOs in terms of cooling efficiency but don’t need RGB fans or a system that costs less than $100.

2.NZXT Kraken X53

Another high-end 240mm AIO

NZXT’s Kraken X53 is a worthy rival to the Corsair iCUE H100i. Two NZXT Aer P 120mm fans are used in this 240mm liquid cooler. The fans will spin up to 2000 RPM and create a sound level ranging from 21 to 36 dBA, depending on the CPU load. The NZXT logo and RGB lighting are also featured on the pump head.

The Kraken X53—and all of NZXT’s Kraken AIO coolers—comes with a six-year warranty, one of its most notable features. Another aspect that distinguishes the NZXT Kraken X53 from the Corsair H100i is its style. The NZXT Kraken X53 has an all-black style, unlike the H100i, which has a black radiator, black fan casing, and white fan blades.

In my view, since the two coolers would work similarly in the grand scheme of things, the Kraken X53’s neutral all-black design would likely make it a more appealing choice for anyone concerned with aesthetics. However, if you don’t mind the H100i’s white-black colour scheme, you can get it for around $10 less.

Best 240mm AIO Cooler w/RGB fans

MSI has long been a significant player in the PC hardware industry. It is, however, a relative newcomer to the world of AIO coolers. But that hasn’t stopped the reputable company from offering one of the best AIO cooler lineups on the market. The MSI MAG CORELIQUID is one of the best 240mm AIOs available right now.

That is particularly valid for anyone looking for a 240mm RGB air cooler preinstalled.

The dual RGB fans on the MAG CORELIQUID can spin up to 2000 RPM and work at a relatively low noise level of 14-34 dBA. At its quietest, it’s just marginally louder than the Corsair 240mm aio iCUE H100i, and it’s quieter than the H100i at its loudest.

The CORELIQUID also has an RGB pump header, is similarly priced to the H100i, and is compatible with both Intel and AMD’s most recent CPUs.

Overall, the MSI MAG CORELIQUID is an excellent 240mm AIO choice for anyone looking to improve their system’s CPU cooling efficiency while also adding some extra RGB lighting.

4.Corsair H100i RGB Platinum

The best white 240mm AIO cooler

Corsair’s H100i RGB Platinum SE is another 240mm AIO with RGB lights that might work for you. Since it is more costly than the other choices on this list, the H100i RGB Platinum isn’t suitable for all. On the other hand, its all-white architecture makes it an excellent option for gamers who want to create an all-white gaming PC.

The H100i RGB Platinum’s two 120mm fans will spin at up to 2200 RPM and create a maximum noise level of 36 dBA.

However, while the H100i is one of the best performing 240mm AIOs on the market, it is also $40-$100 more expensive than the other coolers in this guide. If you don’t need a white AIO to match your build, one of the other coolers mentioned above or below would be a better fit.

5.Cooler Master MasterLiquid ML240L

The most affordable 240mm AIO

Who says a 240mm AIO with RGB fans can’t be had for under $100? And that’s just what the MasterLiquid ML240L from Cooler Master has to offer: a dual 120mm RGB fan AIO for under $75.

In terms of cooling efficiency, this cooler is also no slouch. The MasterLiquid ML240L will provide solid cooling and allow for good overclocking potential thanks to fans reaching speeds of up to 2000 RPM. It won’t blow you away, but then again, you shouldn’t expect it to for less than $75.

The truth is that if you’re designing a budget gaming PC and have enough money left over to have this cooler, you should be overjoyed. It will not only add RGB to your design, but it will also provide significantly better cooling than a stock CPU cooler or a less expensive aftermarket air cooler.

And we’ve included five solid choices in this guide to assist you in finding a 240mm cooler that meets your requirements.

How to install 240mm air cooler?

This is a step-by-step guide for those interested in getting into the world of water cooling. This is How to Put an All-in-One Cooler Together! We’ll be using our 240mm Water 3.0 AIO and mounting it on an AMD CPU for this tutorial. Also, bear in mind that if you’re using a different AIO or an Intel chip, the setup can vary slightly.

  1. To begin, remove all of the components. It’s also a good idea to keep the installation guide on hand if you need to refer to it.
  2. If you’re updating, remove the graphics card first with a screwdriver to obtain more accessible access to the motherboard.
  3. Lay the machine flat now. The stock cooler can be removed next by loosening the screws that keep it in place.
  4. Next, strip all of the old thermal paste from the CPU with isopropyl alcohol and a rag.
  5. Although these next few parts’ order is exceptionally subjective, we believe it is best to mount the fans to the radiator. First, decide which way you want your fan cables to face, as you want them to travel the shortest distance out to the back of your case to the plugin. You’ll also need to determine which way your AIO’s tubes should run to the water block. Most of the time, you’ll want to keep them out of the way and make sure they don’t interfere with your back exhaust fan.
  6. Begin screwing in the fans with the longer screws offered. It’s time to move on to the water block after you’ve secured both fans.
  7. Depending on your CPU and motherboard, this is where things can vary for you. To decide which bracket to use, consult your installation guide. If your socket is an AM4 like ours, you’ll want to use the circular bracket as shown.
  8. Second, thread this thumbscrew through the upper portion of the first bracket, then through the loop. It’s a brilliant idea just to go halfway up because the slack will come in handy later. Thread this through the water block, making sure the screwed-on side is on top. This, once again, will be crucial later!
  9. Assemble the bracket by aligning all of the small cutout parts with the corresponding ones on the water block.
  10. Next, loop the circular bracket over the water block as well.
  11. This is where the fun (or pain) starts! The four parts must be lined up with the first bracket and tucked under it. Don’t worry if it takes a while and causes you a lot of irritation. Since they can be finicky, a pro tip is to use a flat head screwdriver to help nudge them under. When all four have slipped under properly, you’ll be able to tell because the brackets will be fixed in place around the water block.
  12. Now that the nightmare is over, we’ll remove the back panel of the case to mount the back bracket removed when the original stock cooler was removed. You may not need to do this, but if you do, bear in mind that the front brackets should be pointing away from the CPU.
  13. Now it’s time for the installation to begin. Release all of the wires from their cable ties if you haven’t already. Consider where you want your radiator to go in the future, as well as the most straightforward way for your wires to fly out to the back of your case.
  14. Thread all of your wires in, and then pull your radiator up to where you’ll instal it by following the wires. Screw it in with the smaller screws now.
  15. It’s time to place your water block on your PC, so lay it flat. There’s no need to think about thermal paste for any of our Thermaltake AIOs because it’s already installed. Bring the bottom of your water block over the bracket you built earlier and hitch it to your CPU. Then repeat the process for the end. If you didn’t fully tighten the thumbscrew earlier, this should be a lot simpler for you now.
  16. Following that, two cables are coming from the water block to remember. If your motherboard has a pump fan header, the smaller one attaches to it; if not, a device fan header will suffice. You’ll thread the longer one out the back with the other RGB cables.
  17. It’s time to turn on the television! To make it a little simpler, keep your power and RGB cables apart. By connecting all RGB cables, you can build a daisy chain, with just one remaining cable going into the back RGB panel.
  18. On your motherboard, look for two fan headers labelled SYS Fan. This is where you’ll plug in your power cables. Thread the wires back through the closest opening before inserting them into the two fan ports.
  19. To tidy things up, do some cable management and, if possible, reinstall your GPU.

Who makes the best AIO coolers?

Since the invention of the all-in-one (AIO) liquid cooler, Asetek has been solving thermal problems. Our liquid coolers provide outstanding efficiency and unsurpassed dependability. About seven million coolers have been delivered to address thermal problems for gamers, fans, and data centres.

The best AIO cooler should be able to work in tandem with any of the best gaming CPUs. Despite improvements in performance-to-TDP ratios, processors can still get very hot these days, especially if they are overclocked. If you’ve learned how to overclock your CPU and want to put your knowledge to the test, one of the best liquid coolers could be a better option than an air cooler. Overclocking may become more popular as more graphically intensive games like Metro Exodus are published. With a good AIO cooler, you can overclock to get more efficient while reducing the chance of your CPU melting to a crisp.

With all-in-one (AIO) liquid CPU coolers from Cooler Master, NZXT, and Corsair, we put the top cooling manufacturers to the test on our test bench. But why should you waste so much money on a CPU cooler? If you want to optimize your processor’s clock speeds, you’ll need to make sure overheating isn’t a problem, which is where liquid coolers come in.

How to refill an air cooler?

Closed-Loop liquid coolers, also known as AIO (All In One) liquid cooling systems, are sealed coolers. Since they can’t be refilled in the first place, they don’t need any maintenance. However, since water can evaporate through the tubing, some AIO coolers are designed to be refillable by the consumer.

AIO coolers work in the same way as a car radiator does. A pump mounted on top of your CPU circulates a special liquid (usually a mix of distilled water and a thermally conductive fluid) through a closed-loop soft tubing system.

Closed-loop coolers tend to have permeation problems after around 5 years, so if you have a long service life and a thread ripper workstation, you may want to hold the cooler for another 5 years more. If you hear pump gurgling noises or air being sucked through the loop before deterioration, that means there is permeation, and the liquid is beginning to seep into the tubes. So, as we did, take it apart, drain what’s in there, and then refill it to about 200 millilitres plus or minus whatever’s leftover.

Best white air coolers

While many PC builders are focused on raw cooling efficiency, the aftermarket cooling market allows you to express yourself.

This article will help you find the right match for you, whether it’s a budget air cooler or a feature-packed all-in-one (AIO) liquid cooler, whether you’re trying to compliment your white PC build or want to stand out from the crowd.
