Best CPU Cooler for i9 12900K Reviews

The Pros:

  • Has a good ram clearance
  • Amazing cooling performance
  • Good build quality

The Cons:

  • Relatively expensive
  • not a huge color scheme

It would make more sense to use an AIO cooler for a power-hungry processor such as the i9 12900k. But, if you would rather prefer an air cooler over liquid, this is the Best Air Cooler For i9 12900K one you can get. Noctua NH-D15 is the best air cooler out there and is a perfect fit considering the price point on the new processor. This one comes with an LGA 1700 mounting and will pair well with the Alder Lake CPU. This cooler is a monster, and, in some cases, it can surpass the more robust 240mm AIOs. This one has two fans and a fan speed of 1500 RPM. You can get this cooler in white as well as black.

The i9 12900k is an extreme CPU and can get heated up pretty easily. It uses all of its 16 cores under extreme loads and can use up great power. For this reason, Noctua NH-D15 will be fine for gaming and light usage but will not be suitable for CPU-intensive applications. Noctua NH-D15 is 165mm in height which means that you will run into some issues with space if you don’t have a big enough case. This is especially the case if you’re trying to also put in taller RAM sticks. No doubt it’s one of the best CPU Cooler for i9 12900K that is worth considering in 2022.

The Pros:

  • Beautiful looks
  • Amazing thermal performance
  • pre installed RGB's

The Cons:

  • A little noisy
  • A bit expensive

Deepcool Assassin III is a humongous cooler. This is another option for those who prefer air cooling over liquid. This one comes with 2 fans that can work at 1400RPM. In some cases, it may be considered an alternative to the NH-D15, though, it can win against it in others. Deepcool Assassin III is a cooling option for gamers and is one of the best cpu cooler for i9-12900k. If you do decide to get this solution, you need to keep in mind that this one isn’t built for people who are trying to do more than gaming and web browsing and it will not be enough if you’re looking for rendering, editing, mining or other CPU intensive tasks.

One thing to keep in mind is that this cooler doesn’t come with the LGA 1700 mounting kit. However, you can still order one for free with proof of purchase. You will also run into space issues with this one just like NH-D15. And more so if you decide to use taller RAM sticks. So better opt for a larger case. In the case that you don’t prefer a chunky case or you want to use your PC for more than gaming and browsing, we would suggest you go for a 280mm AIO or larger.

The Pros:

  • Aesthetically appleasing
  • Excellent quality
  • Mind stunning performance

The Cons:

  • Not quite compatible
  • Design wont be so attracting for everyone

Arctic Liquid Freezer II 240 is one of the best 240mm AIOs if you are keen on both noise and thermal performance. This AIO is extremely quiet even at speeds of 1800 RPM and its thermal performance is similar to that of the best air coolers on the market. The Arctic liquid freezer is another option for those of us looking to build a gaming PC. This one again is not for you if you’re going to sweat all 16 cores of the i9 12900k, even though it can restrain the CPU in some cases.

This best i9-12900k cooler has a two-fan build with an additional 9mm fan on the main block that is meant to cool the VRM. This is great for Mini ITX motherboards which have less powerful VRMs that may get hotter under load. Now if you’re using an SFF case your PC may get a bit toasty but nothing too concerning.

While the Liquid Freezer II lineup is nice, it may not be the prettiest kid on the block. These coolers are built to be practical. The fans used in the design are Arctic P12 PWM which are one of the best budget CPU fans around. The radiator and the CPU block are thicker and the hoses are also thickly sleeved. Lastly, due to the thicker design, you may not have enough space in the case, so better get a big enough case.

The Pros:

  • Lower noise
  • Reasonable rate
  • Excellent performance

The Cons:

  • too thick sometimes to fit
  • Only seller based warranty available

The Arctic Liquid Freezer II 280mm version is noticeably better than the 240 mm version. The thermal performance is much better even at a lower speed of 1700RPM. This is a great option if you have room for it. Most SFF cases won’t have enough space for this one so you need to get something a bit larger. This one is a better option for those who plan to work their CPU to its limit but don’t want to spend the extra buck getting a 360mm AIO or larger.

Now we know that the Liquid freezer II is not the best-looking option out there, so if this is important to you and you would rather prefer a flashier option, read ahead. We still have a couple more options for you. However, aesthetics is not always the top priority for some of us and performance plays a vital role too. If that’s the case for you, Liquid Freezer II 280mm is an excellent AIO cooler and is also the Best Budget Liquid Cooler For i9-12900K.

If you don’t mind spending a little extra cash and want performance that is comparable to the best AIOs on the market, you could also opt for the 360mm version of the same Liquid Freezer II. The performance is just shy of a few degrees while the price difference may be massive. The Arctic Liquid Freezer II lineup is the best bang for your buck if you don’t care about RGB which can easily drill massive holes in your pocket. You can get a 360mm version and a 240mm version for the price of a 240mm RGB cooler such as NZXT Kraken X73 RGB. Just make sure your case fits one of these before making a purchase.

The Pros:

  • Best build quality
  • Five years waranty
  • Comes with a 60mm pump mounted fan

The Cons:

  • Noisy under high temperatures
  • Might not be affordable for everyone

MSI MEG Core Liquid S280 is the best 280mm AIO out there. This one is an excellent option for both gamers and professionals who are looking to sweat their CPUs. This best CPU cooler for i9-12900k uses the 140mm version of the new Silent Gale fans and boasts a thermal performance comparable to the 360mm versions. Despite running at speeds of 1800RPM, the fans on this cooler are extremely quiet. The CPU block on this cooler holds a small fan that works to decrease VRM thermals.

The MSI MEG CoreLiquid S280 comes with a surprise. The cooler includes a 2.4-inch IPS screen which you can use to display anything you like from GIFs and personalized texts to various system specs. This AIO will ship with the LGA 1700 mounting bracket, so you don’t worry about compatibility with the i9 12900k or order one from MSI.

This Best MSI Liquid Cooler For I9-12900K is although an excellent piece of hardware, is still a chunky boy and you might want to look out for space issues when going with a smaller case. Another drawback to these coolers is that they cost a lot amount of money, higher than even the priciest AIOs on the market. But if you don’t mind the cost and are okay with chunkier AIO and bigger cases, then we say go for it.

The Pros:

  • Has RGB
  • Exceptional cooling
  • Has an 7th Gen Asetek Pump

The Cons:

  • expensive
  • doesn't have fan control

No PC hardware list would be complete without one option for the bling à la the RGB. There are a few AIOs that come close to NZXT X73 RGB when it comes to aesthetics. This AIO may be the ‘coolest’ on the market. Get the pun? This one is all about looks. The white version of the cooler looks exceptional and the main block features an infinity mirror effect which is a nice touch.

What’s even better is that this AIO has excellent thermal performance. The cooler comes in a 360 mm design which features 3 fans. You can also get the 280mm of the AIO called X63, which features the same aesthetics but in a 2 fan design. Both versions show excellent noise performance, however, the X73 is noticeably quieter under extreme load. You might not have an LGA 1700 mounting bracket in the box, so you’ll have to order it from NZXT.

This cooler comes at a price premium and it doesn’t even make sense about bang for your buck here. You could get a Liquid Freezer II 360 and a Liquid Freezer II 240 for the price of one Kraken X73 RGB. However, if you believe that you can’t put a number on aesthetics and you just have to have the prettiest AIO ever, then it doesn’t get any better than this. If you are too fond of RGB lights and looking for the best CPU cooler for i9 12900K then this one will be a great option for you.

The MSI MEG CoreLiquid S360 like its 280mm cousin is a behemoth and probably the best AIO cooler on the market. The Silent Gale P12 fans used in this cooler are the best you can get so you don’t have to worry about the thermal or noise performance.

This Best 360mm AIO Cooler For Intel Core i9-12900K comes with all the features, the 280mm option comes with, including the VRM cooling fan, 2.4-inch IPS screen impressive thermals the whole shebang. The cooler also comes with LGA 170 mounting bracket in the box so there’s one less thing to worry about. The performance of this cooler is more than exceptional and as per our tests, we’ve found that it’s the best CPU cooler for i9 12900K to consider.

The MSI MEG CoreLiquid S360 like its cousin is also a chunky boi and costs ridiculous amounts of money. But if this price point doesn’t give you nightmares and you would, REALLY like a large LCD screen, there is no better AIO out there than this one, except, if you stop to consider all the competition.

The Pros:

  • 1

The Cons:

  • 1

Arctic Liquid Freezer II 420 like the others in the lineup is built for function and not for style. The 420mm AIO is probably overkill, even for the beast that is the i9 12900k. This will provide you with dead-silent performance even under considerable load. The cooler comes in a three-fan design that reaches speeds of 1700 RPM. The thermal performance on this cooler is amazing and is exactly what you would expect from 420mm AIO.

These coolers will give you the most bang for the buck, with prices rivaling that of mid-range 360mm coolers and a performance that is definitely on another level. This one may not be intended for aesthetics. But if that’s your game, Liquid Freezer II 420 also comes with an RGB and A-RGB version so you’ve got that department covered too.

The drawback again with this AIO is that the design is a bit thicker like the rest of the Liquid Freezer II Lineup. So if you can fit this AIO in your setup, go for it. Overall if you manage to get it I’m guaranteeing you that this will be the best CPU cooler for i9 12900K in 2022.

The Pros:

  • exquisite pump design
  • has a RGB PWM fan hub
  • 6 fans

The Cons:

  • can be noisy when fans are working at their highest speeds
  • not a great value

In conclusion, now that we have reached the end of our list, we are going to take a look at one of the coolers that perhaps has the best performance out of the entire list. Despite the fact that it might seem ridiculous at first, this naming scheme seems to make sense for a cooler that is as complex as this, regardless of how ridiculous it might seem at first glance. While the Elite 360 cooler may not be as impressive at first glance as the other two options above, it is still a great addition to any enthusiast’s collection.

EKWB is one of the leading manufacturers of water cooling components for gaming PCs and has been manufacturing these components for quite some time now. There is a lot of experience they have in this field. In fact, these closed-loop systems have enabled them to create something that is truly phenomenal, even though most of the products they offer are components for custom loops that they make for other companies.

There is no denying the fact that a huge cooler like this does come with its downsides, which goes without saying. The thing that you are looking at is quite well designed, as you can see, and it is purely designed keeping performance in mind, which makes it a very good choice. Before we move forward with the discussion, it is important that we clarify a couple of things before we begin. As far as AIOs are concerned, EK has a wide selection of AIOs to choose from. If you have a 360mm radiator, you can choose from the Elite D-RGB 360, D-RGB, or the EK Basic, which all work with 360mm radiators.

There are six fans included with the one we are looking at, and a fan controller is included as well. It should be noted that the basic version does not come with RGB nor a fan controller, while the non-elite version comes with three fans and does not have a fan controller either. Yeah, the product stack here is quite confusing. We feel it is important to clarify this as soon as possible so that you do not receive the wrong version.

The density of the fins, which are stacked very closely together, is quite high because of the fact that they are stacked so closely together. It is expected that the dissipation of heat will be more effective with a surface like this one.

As well as being designed in-house by EK, this pump is also an alternative to an Asetek design, which puts it in a much more cost-effective position than using an Asetek design. I think it is safe to say that the whole combination is quite heavy, and if you were to ever drop it, it would likely cause some damage.

There are some who may not be interested in this high-end AIO, since cable management can be quite a hassle, and the entire package is rather expensive. In our opinion, the one for the enthusiasts is this one, if you’re looking for the best possible build quality, performance, and high-end looks that you can get from a smartphone. Indeed this is one of the Best CPU cooler for i9-12900K.


In terms of gaming performance, the Intel Core i9-12900K is the world’s most powerful gaming processor, offering performance unmatched by any other gaming processor at this price point.
