These Are The Best CPU Cooler For Intel Core i9-14900K and 13900K CPUs

If you are looking for an Intel CPU cooler for a new gaming machine or simply upgrading an existing one, we listed some of the best here. The 14th gen Core i9-14900K is Intel’s latest flagship desktop processor, but it is very similar to its predecessor, the i9-13900K. Both have the same architecture, core and thread count, cache size, TDP, and even launch price. Since they are identical in many ways, both CPUs consume a lot of power (up to 253W), thus producing a lot of heat and requiring an excellent AIO liquid CPU cooler. Below, I listed some of the best CPU coolers for the Core i9-14900K and i9-13900K CPUs.

The Best CPU Coolers For the Core i9-14900K and 13900K That We Pick

Let me first discuss how I chose these CPU coolers and my criteria. The beauty of the DIY market is that there are many options. Since the Core i9-14900K and 13900K draw a lot of power and can get hot, reaching 100°C easily, the CPU cooler must be an all-in-one closed-loop 360mm liquid CPU cooler. It must also be compatible with socket LGA 1700 and, most importantly, perform well.

It would be a plus if the AIO CPU cooler has an LCD screen, attractive RGB lighting, and is easy to install. Normally, I would not skimp my budget since the AIO CPU cooler will protect and keep the CPU cool. It has a crucial role in keeping the system running smoothly. While even the most trusted brands are infallible regarding product failure, I’d still pick a CPU cooler from a trusted company.

Lian Li Galahad II LCD SL-Infinity 360 AIO – If You Love RGB


First on my list is the recently released Lian Li Galahad II LCD 360 AIO liquid CPU cooler. It’s new, and there’s not a lot of feedback yet. But Lian Li’s Galahad II series was an excellent AIO CPU cooler overall. Considering the company’s reputation and the fact that the Galahad II LCD sports Asetek’s 8th gen pump design, the Galahad II LCD is a pretty good choice for cooling the 14900K or 13900K.

What makes this AIO CPU cooler so interesting is its 2.8-inch LCD display that can display up to 2GB of videos or up to 3 minutes of footage, aside from the usual system information. There are also 45° angled fittings at the radiator with a full 360° rotation that you don’t usually see in most AIO closed-loop CPU coolers. The variant I’m also picking is the one with the SL-Infinity fans. Not only do the RGB lighting and aesthetics of these fans look great, but they are also cable-free daisy-chained fans, resulting in less cable clutter inside the system.

ASUS ROG Ryujin III 360 ARGB AIO CPU Cooler – Best but Premium

ASUS ROG Ryujin III 360 ARGB AIO CPU Cooler-01

The Asus ROG Ryujin III 360 ARGB is among the best-looking AIO liquid CPU coolers in the market. It’s an improved version of the Ryujin II, which in itself is already an excellent CPU cooler. The ROG Ryujin III features Asetek’s 8th-generation pump design with a 3-phase monitor for a more robust performance. It also features a large 3.5″ LCD screen for live system stats, animated GIFs, or custom artwork.

Like its predecessor, the Ryujin III 360 ARGB features an embedded Axia-tech fan for VRM cooling. Another thing I like about this is its magnetic daisy-chainable ARGB fans for a cable-free and clean-looking build. It also features 7mm sleeved rubber tubes, a new and larger cold plate, and a thicker radiator. Finally, Asus released the Ryujin III 360 ARGB EVA-02 Edition for Evangelion fans, featuring bright red and orange accents.

ARCTIC Liquid Freezer III 360 A-RGB – Best Budget AIO

Arctic Liquid Freezer III 360

The Liquid Freezer III 360 A-RGB is Arctic’s latest AIO liquid CPU cooler. The independent review community gave this AIO CPU cooler an overall excellent feedback and recommendation. 

Arctic made several improvements, and the new Liquid Freezer III features a 38mm thick radiator—23% larger than its predecessor. It also features a proprietary PWM-controlled water pump, an improved coldplate with a larger fin surface, and an updated VRM fan.

It also includes an MX-6 thermal compound, providing everything necessary for a fast and straightforward setup. The Liquid Freezer III is compatible with Intel’s upcoming Arrow Lake processors on the LGA1851 socket, and it will work with the new socket without any issues.

Unlike the other AIO CPU coolers listed here, Arctic is forcing you to use its contact frame included in the box. And because of this, installation can be a hassle for Intel setups.

CORSAIR iCUE Link H150i RGB Liquid CPU Cooler-01

For those who are building a system primarily composed of Corsair peripherals, like fans, case, etc., the iCUE Link H150i RGB AIO would be an excellent fit. It’s the latest from Corsair, and it comes with the iCUE Link System Hub, where you can integrate and connect compatible Corsair peripherals. Its radiator is paired with QX120 RGB cable-free and daisy-chainable fans for a cleaner-looking build. Not to mention, there are thermal probes to monitor the air’s temperature.

The iCUE Link H150i’s copper cold plate features a split-flow design (inside) and comes pre-applied with Corsair’s XTM70 thermal paste. The main takeaway of Corsair’s iCUE Link H150i is aesthetics. If you want a clean-looking, centralized RGB fan system and clutter-free build, this AIO may fit your bill.

Optional Steps To Further Improve CPU Temperature

CPU Contact Frame for LGA 1700

Intel’s LGA 1700 is notorious for having an imbalance of pressure when locking the CPU. Some manufacturers have made anti-bending brackets or contact frames to mitigate this issue.

The contact frame, a.k.a anti-bending bracket, replaces the motherboard’s independent loading mechanism (ILM). The contact frame will help in the distribution of the pressure, thus better and even contact on the CPU block’s surface. As a result, it may help lower the CPU’s temperature.

Note that installing this requires a bit of tinkering. You must remove the ILM and replace it with the contact frame. It’s very risky since there is a chance that the pins on the socket may get damaged or the motherboard itself may get damaged. When installing the bracket, you must apply a sufficient amount of force, not too tight or loose. Otherwise, it may affect the motherboard’s traces and cause damage or unwanted errors.

Quick FAQs

Does the Intel Core i9 run hot?

Unfortunately, yes. The Intel Core i9 14900K and i9 13900K can run really hot, especially if the limits are disabled and you just let the motherboard supply all the power that the CPU consumes. It can reach over 100°C or more, but it is not recommended.

What is the safe temperature for Intel’s Core i9 CPU?

While the CPU can handle temperatures around 90°C to 100°C, I would want my CPU to reach those temperatures. Preferably, I’d keep the temperature around 85°C or below when in a full load. Obviously, during light CPU load, I expect the temperature to be much lower.

Does the Intel Core i9 CPUs (really) need water cooling?

Not really. You can get away with a tower-type air cooler. However, expect the CPU’s temperature to be on the high side most of the time. It could reach more than 90°C in full load. While you can use something like the Noctua NH-D15 to cool a Core i9 CPU, an AIO liquid CPU cooler can do better.

Can you use a 240/280mm radiator instead of a 360 AIO?

Yes, but expect that the temperature is on the high side. If you are gaming or doing non-heavy workloads, a 240/280mm radiator can handle it. However, it’s best to use a 360mm radiator to keep the CPU cool if you do CPU-intensive workloads like rendering.

There you have it; these are my top picks and the best CPU coolers for the Core i9-14900K or i9-13900K. It’s up to you what you prioritize in your system. These AIO CPU coolers offer better CPU temperature and/or a better-looking (gaming) rig. If I had to choose one, I’d pick the Ryujin III 360 as it fits my use case and build.

I hope you liked the AIO CPU coolers I picked for the Intel Core i9 14900K and 13900K. ThePCEnthusiast is supported by its readers. When you purchase products via our links, we may earn a small affiliate commission at no extra cost. Thank you for your support!
