If you want the best AIO cooler for your i9 14900K rig, then we believe that the Corsair H150i LCD XT is one of the best AIO options on the market right now.
To start with, this is probably one of the largest coolers you can get from the brand. It has three fans placed on a 360mm radiator, which should give you an idea of the powerful performance it can deliver.
In our review, we tested the CPU to see the performance for ourselves. We tested for everyday performance as well as pushed it probably far beyond anyone would under standard use. And the CPU did very well.
We tested for everyday performance as well as pushed it probably far beyond anyone would under standard use. And the CPU did very well.
To be more specific, while idle, the average temperatures were 27 and 29 degrees under full fan and balanced modes, respectively. These numbers are not too far away from the ambient liquid temperature of 28.13 degrees.
Further, during the 5-minute Aida stress test, the temperatures under full-fan and balanced modes were 79 and 84 degrees, respectively. While these numbers may seem high, note that these are extreme scenarios that are unlikely to occur during everyday use.
As far as design is concerned, there are two parts in the block – one contains a water pump and the other has a 2.1-inch LCD screen on the top. This separation makes installation easier and minimizes the chances of damaging the screen. Plus, the screen can display system info or you can choose to display memes.
On Amazon, the Corsair H150i LCD XT cooler has a rating of 4.2 stars, and it has been rated by more than 2,900 buyers. As per the reviews, customers were happy with the cooling performance and mentioned that they noticed significant drop in CPU temperatures. Customers also liked the appearance of the product – especially the RGB lights on fans. However, users had mixed opinions about installation.
If you have a creative workstation with a powerful CPU like the 14900K, then we think that the ASUS ProArt LC 420 is the best choice.
Much like the name suggests, the ProArt is a cooler designed for creatives or people who regularly put a lot of strain onto their CPU. As mentioned, this cooler comes with a big 420mm radiator – so you’ll need to ensure that your rig can accommodate it.
Much like some other Asus coolers, this one also features fans from Noctua. To be specific, this cooler has Noctua NF-A14 Industrial PPC-2000 140mm fans that are capable of delivering 2000 RPM, which explains how efficient this cooler can be.
We have reviewed this cooler in-house, and right off the bat, we’d say that we liked it. The cooler is big and it is expensive, but it’s worth the price if you have a powerful rig. However, if you don’t strain your system a lot, then you can consider going for a 360mm cooler.

During our review, we stress-tested the cooler in idle condition as well as the Aida test – and it performed very well. To give you a better idea, the temperatures did not exceed 33 degrees and 72 degrees at idle load and extreme load, respectively. These are pretty impressive numbers. We also tested the temps for Blender, for which we’d encourage you to read our detailed review.
Overall, this is a robust cooler that can handle high-performing CPUs like the i9-14900K. Plus, there is considerable headroom here if you decide to upgrade your CPU in the future.
On Amazon, the ASUS ProArt LC 420 AIO cooler has a rating of 5 stars, and it has been reviewed by 3 users. “I put this in a ProArt PA602 case and it fits perfectly. Works great keeping a Ryzen 9 7950X3D nice and cool,” one of the customers wrote in a review.
If you want a more reasonably priced cooler for your i9-14900K rig, then the Cooler Master MasterLiquid 360 Atmos might be a good fit.
As mentioned, this is one of the most affordable picks on this list, and yet the performance is on par with some of the costlier coolers that we have tested. However, it lacks fancy features like an LCD display, which might actually appeal to users who like to keep it basic. Overall, it’s a no-nonsense pick in terms of design and performance.
Another thing that we’d like to note is that the Sickleflow edge fans come pre-installed, so you can skip a step during installation. Plus, these fans can spin up to 2500 RPM and deliver 70.7 CFM of air, with a 27.6 dB(A) max noise level.
This is one of the most affordable picks on this list, and yet the performance is on par with some of the costlier coolers that we have tested.
We tested the Cooler Master MasterLiquid 360 Atmos, and we were pretty impressed with the results. In the idle state, the cooler managed to keep the average temperature at 28 degrees. Meanwhile, during the Aida stress test, the average temperature was 59 degrees and it did not exceed 77 degrees. All of these are impressive numbers for a cooler at this price.
As far as design is concerned, it doesn’t have too many bells and whistles. It looks sleek and attractive, and you can choose between black and white options. Instead of a screen, you get a window through which you can see the heat sink and other parts. Plus, you also get RGB lights that you can turn off.
On Amazon, the Cooler Master MasterLiquid 360 Atmos has a rating of 4.4 stars, and over 400 buyers have rated the product. As per the reviews, customers were satisfied with the cooling performance, noise levels, and also appearance. “Looks great but most important very efficient and silent,” one of the customers said in a review.
This selection might be surprising, as an air cooler is generally not enough to tame Intel’s flagship processors. However, we’ve reviewed the Noctua NH-D15, and it managed to keep the 14600K at an acceptable temperature, so it should be able to handle the 14900K as long as it isn’t overclocked.
This CPU cooler has a copper contact plate mounted on top of the CPU and comes with high-quality thermal paste pre-applied. However, it is generally believed that you should change your thermal paste at least once a year, so we recommend using the best thermal paste available to ensure that the heat is efficiently transferred from the CPU to the cooler.
That being said, it features dual aluminum heatsinks, which have six vapor chamber heat pipes going through them each, making them 12 in total. There are also two 140mm fans that can be attached to the dual heatsinks, but be careful while doing so, as there is the risk of cutting yourself on the heatsink.
The NH-D15 from Noctua is a fantastic cooler with a brilliant value for money, it is capable of cooling many CPUs in the higher end thanks to it’s double stack heatsink and dual 140mm fans.
The noise level of the Noctua NH-D15 comes to around 24.6 dB(A) while it is pretty quiet, and you shouldn’t heat it running. There is also the option of enabling quiet mode, but the performance takes a hit with that turned on, so we don’t recommend doing that, especially with the 14900K.
To check its cooling performance, we paired it with the 14600K, which has a maximum TDP of 181W, while the 14900K sits at 253W. So, there is a clear difference, but while running the Aida stress test, this cooler kept the 14600K at 86°C with zero thermal throttling. That being said, for causal usage, it should be able to keep the 14900K cool and prevent overheating. We also recommend using powerful 140mm case fans to promote good airflow.
According to Amazon reviews, this CPU cooler is huge, so ensure that you have enough space to install it. besides that, it has good cooling performance. One reviewer used it with the 14900K and had this to say: “This cooler makes the i9-14900k cpu thermal throttle by 5- 9%, meaning it’s getting too got. Need a watercolor to keep the i9 cool. But if you limit it then it’s no problems for thermals.”
Here are a few things to consider before getting a cooler for your rig –
Furthermore, compatibility is of paramount importance. It’s essential to ensure that the cooler fits comfortably within your case without obstructing RAM or other essential components. After all, a cooler that’s too bulky might impede airflow or even prevent the case from closing properly. You’ll need to consider where the radiator will sit, whether on top, on the side, or on the bottom, and how this will impact intake and outtake airflow.
You will come across two types of coolers – AIO (liquid) and Air. Generally, liquid coolers offer superior heat dissipation for overclocking or high-performance tasks. However, you’d need to check case compatibility for radiator size and tubing management. Meanwhile, air coolers are quieter and easier to install but may not be as effective for very demanding use cases.
Coolers can get noisy and cause distractions, so you should look for a cooler that’s not too noisy. Look for coolers with PWM (Pulse Width Modulation) fans for quieter operation at lower CPU loads. Aim for a cooler in the 30-40 dB range at idle and ideally below 50 dB under load for a quiet PC experience.
Coolers come in all kinds of shapes, sizes, and colors, so you can be a bit picky with style. A lot of coolers feature RGB lights that you can customize as per your preferences. Some high-end options come with an LCD screen that can display system information or even memes. If you don’t want any bells and whistles, then you can choose a no-nonsense design.
While we would generally recommend investing in an AIO water cooler instead, air cooling can be a valid and cost-effective option for those after a cheaper way to keep their chip chilled. The one we’ve included in our roundup has enough grunt to work well, but you won’t be able to overclock or push your games as hard.
Yes, a 240mm radiator and pump combo should be enough to adequately cool an i9 14900K. We would recommend going for a 360mm if you have a large enough PC case for overclocking overhead, but you shouldn’t experience any issues with a slightly smaller radiator mounted.
