You might be wondering why we’re not recommending the RGB version here. Well, while the performance of the fans on that version is quite good, the RGB lighting is just a subtle afterthought.

RGB fans are much more interesting these days than just a simple lighting setup. For design uniformity reasons, you’re much better off getting fans separately for this version as you can match them with the other case fans.

Now, let’s talk about the design for a bit. Arctic has decided to go with a custom design for the pump found on this CPU cooler. Many companies rely on Asetek for their pumps, and there is nothing wrong with that. However, Arctic went to great lengths to perfect their in-house developed pump, and it pays off quite well.

For starters, this cooler is nearly silent, even when it is working at maximum load. That’s not something you see every day, and it’s a testament to the engineering shown off here. They are also using a thick 38mm radiator, one with a high fin density. This allows more water to move through the system, making cooling more efficient.

As for the tubing, it is fiber-reinforced and the length is quite good. These tubes also feature cable management channels, and this allows you to easily hide the PWM and RGB cables. So, it may not look all that flashy, but a lot is going on with the design here.

The fans here are great as high static pressure fans, and they can spin up to 2000RPM. They never get too loud, and that’s a huge plus point. They don’t vibrate too much, nor do they make much noise.

How To Choose The Best CPU Cooler For i9 12900K

A CPU cooler is just as important as the motherboard or even the processor itself. All three components are interdependent. So, it is imperative that while searching for a CPU cooler, you find one that is suitable for your needs and compatible with the other two components we just mentioned.

This is even more important when we are talking about a high-end processor like the i9 12900K. The 12th gen processors are certainly impressive, but right now they can prove to be hard to justify for some people. You have to take into consideration that you’re not only buying the new CPU, but you’re also buying into the new platform entirely.

For an unlocked chip like the 12900K, you’ll need a Z690 motherboard. Since you’re already aiming for the best performance possible, you’ll also need DDR5 RAM. For the entire cost of just these three components, you can put together a very capable PC on its own. So, the value aspect is a bit skewed.

Of course, the processor isn’t just for gamers. It’s for content creators, working professionals, and hardware enthusiasts. That makes it even more important that you find the best CPU Cooler for i9 12900K.

Air Cooling vs Liquid Cooling

As someone who has been involved within the PC building community for a while, I’ve seen this question come up time and time again over the years. It’s a long-running discussion between both newcomers and veterans. So, what’s the right answer.

Well, the thing is that the entire decision is quite subjective. If you’re going with a beefy 360mm cooler for a low-end processor, that does not make any sense. On the other hand, if you’re using a cheap entry-level air cooler with the 12900K, then that decision escapes common sense as well.

Both have their advantages. For example, some might say air coolers are simpler and hence more reliable. They don’t have as many moving parts and are less prone to failure. For example, if a fan fails, that’s an easy replacement. On the other hand, if the pump on an AIO fails, you’ll have to RMA it or abandon it completely.

Liquid coolers or AIOs also have their obvious advantages. You get a radiator that can store water and with the help of tubes, carry it to and from the CPU block. This might do a better job at cooling, depending on the performance and quality of the components used. To some people, they also look better.

So, you can hopefully figure out how these things are subjective. Some prefer the reliability of air coolers; others may find that liquid coolers perform better. Of course, there are always exceptions on either side.

That should bring you up to speed, but we have covered this topic in depth if you are more interested. 

Compatibility between components

This is even harder to get right given the current global situation. If you’re not already aware, there is a shortage of computer parts going on. Even though things are slowly getting better, we don’t know for how long that’s going to be the case.

Of course, you need powerful cooling for a processor that is as demanding as the 12900K. Then again, case compatibility can be a bit of an issue. For ITX or mid-tower cases, fitting a gigantic dual-tower cooler like the NH-D15 can be a problem at times. Some cases might not have support for 360mm radiators either, so many of the best coolers are already out of the equation.

Fortunately, many liquid coolers offer nearly the same level of performance, just with 240 or 280mm radiators. Those tend to have better compatibility with a vast majority of PC cases out there.

With air coolers, RAM clearance is something to worry about. Gigantic dual-tower air coolers can sometimes interfere with or even block RAM slots. If you plan on using RAM modules that are taller than usual, this can be a bit of an issue. Some manufacturers such as Noctua and Cryorig address this quite well.


Well, if you’re spending this much on putting together the ultimate gaming/workstation PC, it would be a crime if you did not care about aesthetics. This is something worth considering when shopping for the best CPU cooler for i9-12900K.

Some may care about aesthetics in the form of flashy RGB fans or aggressive designs. Others prefer a more muted and stealthy look, something similar to the NH-D15 chromax.Black. Looks are certainly subjective, and that is why it is all the more important that you buy a cooler that you won’t mind looking at years down the line.

Final Thoughts

There are a lot more options out there than just the five of the ones we have picked as the best CPU coolers for i9 12900K. For example, coolers like the Scythe Mugen 5 and Corsair H115i Elite Capellix at least deserve an honorable mention. However, to keep things clear and concise, we aimed to keep the list under 5. These are hands down the best fit for the 12900K, depending on your use case.

If you want to get even more performance out of your 12900K build, or are into putting more into custom PC build, check out custom loops. We have some great roundups such as the best PC radiators and best GPU Coolers. Our coverage on stuff such as the best water blocks for RTX 3080 is also worth taking a look at.
