While we have done our best to give you the most information possible, it is still advisable to review the specs and features to make sure the liquid CPU cooler will work in your configuration.

Let’s jump in and take a look at each one in-depth before making our final decision.

1. Enermax Liqmax III 360: Best Budget 360mm AIO Cooler

Enermax has been making quality liquid coolers for a while now, but the name may not be familiar to you.

They don’t have the huge marketing budgets and reputation as the Cooler Masters or the NZXT coolers.

That doesn’t mean that their products are inferior…not even close.


For what Enermax lacks in brand recognition they more than makeup for in the performance.

My goodness, this cooler is fantastic! It is more than capable of keeping even the most power-hungry CPU at icy cool temperatures giving you maximum overclocking potential.

The large dual-chamber water block ensures you have the best heat transfer and removal possible.

When you combine that with the large radiator and triple fan setup you get a cooler that can handle anything you can throw at it. Robust, heavy-duty, and performance-focused. That is how we would describe this Enermax cooler.


While the performance of this radiator is extremely good, the design is decent as well. They didn’t skimp on anything here, which is surprising given the affordable price tag they put on this cooler.

Three RGB fans are cooling the radiator, all of which have a nice color glow thanks to the white fan blades.

The CPU block has RGB lighting on it as well, so when you mount it on your motherboard you can see the Enermax logo shining in whatever color you choose.

While it isn’t the most flashy design out there, it is just the right amount of RGB for us. If you get too much RBG shining through on one part of your build, it can just distract from the rest of your components.

All in all, this is the best 360mm AIO if you’re on a tight budget.


  • Great performance
  • Nice design
  • Heavy-duty build quality
  • 5 year warranty


  • CPU block is square which some may not like

2. Thermaltake TH360

Thermaltake was once a brand in limbo, not sure whether they should dominate the budget market or take their shot at the more high-end market.

That is over, and they settled on leaning more towards high-end performance, which is working for them extremely well. Take the Thermaltake TH360 cooler, well made and gorgeous in design, the perfect cooler for enthusiast PC builders.


The big and robust radiator on the TH360 lends itself to great cooling performance. When you combine that with the three static pressure fans (at 1500 RPM fan speed) to push a load of air through it while keeping noise level down to minimum, you get the perfect combination for cooling performance.

The CPU block features a nice large copper plate on the bottom to help with heat transfer. The pump inside the block is a high-performance part, moving water at a fast rate, thus cooling your CPU efficiently and effectively. Those are the two words you want to hear when it comes to performance.


When it comes to RGB fans, Thermaltake has some of the nicest on the market.

The three that are included with this setup are stunning to look at and will add a level of smooth lighting you can’t get with some other brands.

So if you are looking for RGB lighting, Thermaltake has you taken care of with the TH360.

The CPU block has a great design as well. The square block has the corners shaved back giving it a unique look compared to the competitors.

The RGB lighting on the block is nice as well, with a subtle glow coursing through the Thermaltake logo. Overall, the design is one of the major strengths of this cooler.


  • Beautiful RGB lighting
  • Very good performance
  • Highly durable pump


  • Higher price than some competitors
  • Just 2-year warranty

3. Cooler MasterLiquid ML360R: Best 360mm AIO Cooler For Value

Only a couple of names come to mind when talking about cooling solutions for your PC, and Cooler Master is probably at the top of that list.

They have been making high-performance CPU coolers at affordable prices for years, and thus have gained the reputation of the king of the crop with many computer builders.

Their MasterLiquid ML360R is a treat with its large radiator and pleasing design choices, carrying on that Cooler Master name as a badge of honor.


Cooler Master has been pushing the limits of computer cooling for years, so it comes as no surprise that their pump and radiator technologies are some of the best on the market.

The low profile CPU block and high-performance radiator are impervious to corrosion and evaporation, meaning this is practically a zero maintenance solution.

The three fans included here are quite good, offering plenty of airflow to keep your components nice and cool.

The pump inside the block is one Cooler Master has been engineering and making better over the years, and it shows. This pump is extremely strong and surprisingly quiet given its low profile size.


First thing first, the RGB lighting on Cooler Master MasterLiquid is one of the best around. It is surprisingly good, and something that can stand against any other unit on this list.

While Cooler Master normally focuses more on the performance side of things, they crushed it with the design of this cooler.

The one thing that some people won’t like is the fan shape. While most fans on these type of coolers are square and thus blend in with the radiator, the fans on this Cooler Master unit are more star-shaped and don’t look quite as clean as some other designs.

Overall, this is the best 360mm AIO in terms of value


  • Low profile CPU block
  • Great pump and radiator technology
  • Good RGB implementation


  • Fans shape is a bit odd

4. DEEPCOOL Castle 360EX

DEEPCOOL is known for their CPU cooling solutions, and their liquid CPU coolers are as good as it gets.

They have some of the best engineering and technologies in the space, and that gives you a high-end level of cooling performance in a liquid cooler that other brands struggle to match.

DEEPCOOL is a brand you should certainly not write off if you are looking for an AIO CPU cooler for your next build.


DEEPCOOL knocks it out of the park with the performance of this cooler. They have some of the best technology in the pump and CPU block of this cooler that other manufacturers can only dream of.

The motor inside is a 3-phase, x-life motor, giving it a ton of power thus increases the flow of water and cooling efficiency.

The pump isn’t the only area where a lot of engineering time was spent, but their fans are tuned specifically for this cooler to give it maximum performance.

They do a great job of pushing air through the radiator, ultimately keeping the entire system nice and cool.


The well-designed fans are all black except for the logo in the middle. They blend in well with the large radiator, but sadly don’t come with RGB lighting.

That will be a negative to many, but it does still look quite nice.

The CPU block does feature RGB lighting, with both the face and a ring around the edge shining bright. It is just enough to not be offensive to most people.

The overall design features here are understated and very clean.


  • Great performance
  • Finely tuned fans
  • Sleek design
  • 3 year warranty


  • Fans have no lighting

5. NZXT Kraken X73: Best High-end 360mm AIO Cooler

NZXT came into the cooling market and crushed the competition that had been around for years. Their sleek designs and almost Apple-like modern builds put their quality at the top of the list.

Need a perfect example of that? Check out the NZXT Kraken X73. It has the cooling performance and the design that will make any hardcore computer builder drool.


The performance is exactly what you would expect from NZXT. It is close to the best there is, and that is no exaggeration.

This massive 360mm radiator combined with their pump and CPU block technology makes the cooling you get out of this combo next level.

The three Aer P fans on the radiator are specifically designed for water cooling. This means the engineers perfected their performance specifically to cool this radiator.

That is all you need to know about this cooler, it is engineered to perfection to provide you with the best cooling possible. But that comes with a price.


Using our Apple comparison from earlier, the design of the NZXT Kraken X73 has a very sleek and minimalist design.

This will appeal to many people out there, as it doesn’t have the harsh lines and sharp edges that accompany many gaming components.

The matte black fans fade seamlessly into the radiator, giving it a stealthy look that will have a wide appeal.

There is RGB in the ring around the CPU block, and they can get quite bright. However, the design remains understated in the best way possible, fading into the background to let your main computer components shine.


  • Fantastic performance
  • Sleek design
  • Bright RGB light on the CPU block
  • 6-year warranty


  • Expensive


And there it is, the best of the best. Take your time and consider what you like about each one before picking your ultimate winner.

No matter which you choose there is no doubt it will keep your system nice and cool.

If we had to pick our favorite of the bunch it would probably be the NZXT Kraken X73. It narrowly edges out the rest with its design and cooling performance, giving it the crown in our books. But again, your mileage may vary, so choose the cooler that is right for you!

Liquid Cooling is steadily becoming popular among PC builders due to less compatibility issues than air coolers.
