Best CPU Coolers for Core i5-11600K: Air & AIO Options

Rocket lake CPUs have been around for a while now, and the one that sits below this lineup is the Core i5-11600K.

Intel’s single-core performance, as always, remains strong. The Core i5-11600K scored impressively in many single-core tests while offering a much better price point compared to the AMD Ryzen 5 5600X.

The Core i5-11600K is a six-core, 12 thread CPU that comes clocked at 3.9 GHz out of the box, and can reach up to 4.9 GHz. It’s unlocked so you can push even further if needed. Pairing this CPU with a decent graphics card will definitely run any modern games you throw at it with ease. In addition, the Core i5-11600K integrated graphics almost doubled the iGPU performance of the previous generation 10600K, which is a nice improvement.

Another thing that is worth noting is that 400 and 500 series motherboards will still work well on the Core i5-11600K. As a result, if you want to move from the previous model, there’s a good chance you won’t need to buy a new motherboard.

The downside is that it doesn’t come with a bundled CPU cooler, so you’ll need to pick that up separately. There are countless air and liquid CPU coolers on the market today, however, not all of them support the LGA 1200 that Core i5-11600K uses. So, we’ve compiled the best compatible aftermarket coolers for the Core i5-11600K.

Noctua NH-U12S chromax.Black

The Noctua NH-U12S isn’t that expensive, yet still a premium CPU cooler from Noctua.

It features a 120mm Single-Tower design providing decent surface area, resulting in optimal heat dissipation. The five high-performance heat pipes have been nickel plated and are soldered to the heat-spreader.

The NH-U12S also comes with a single NF-F12 120mm fan that features an advanced aerodynamic design allowing for reduced noise levels, improved cooling performance, and better static pressure. The fan is excellent and has many great features. It is a PWM fan, so it can be controlled automatically to ensure the best noise and cooling performance possible. Additionally, the fan comes with a Low-Noise Adaptor for even quieter operation.

Noctua also includes their high-end NT-H1 thermal paste, which is one of the best performing pastes on the market. It provides great heat transfer and is extremely durable. Finally, the SecuFirm2 mounting system makes installation a breeze on most sockets, including the new LGA 1200.

In terms of PCIe and RAM compatibility, the NH-U12S is excellent with its slim design, having only 45mm fin depth, making it ideal for setups with limited space.

The NH-U12S is indeed a great entry-level CPU cooler for the Core i5-11600K. It has premium-grade materials and construction, excellent performance, superb value for money, great compatibility, and a flexible mounting system.


Scythe Fuma 2 – Budget Type Cooler

Scythe Fuma 2

The Scythe Fuma 2 is our budget but decent air cooler recommendation for the Core i5-11600K. It can deal with high temp CPUs, and its performance is quite impressive at this budget.

It uses dual heatsinks and fans that help to dissipate heat quickly and efficiently. This cooler has six heat pipes and a copper base plate, which helps to absorb heat from the CPU. There are actually 2 included Kaze Flex 120mm fans that are designed to be quiet and efficient. They use a Fluid Dynamic Bearing to reduce noise and vibration. This helps to keep the cooler silent while still providing excellent cooling performance. In addition, both of these fans are PWM, which means you can control the fan speed, and the motherboard will do it automatically. This helps to keep the noise down when the CPU is idle or lightly loaded.

The Scythe Fuma 2 is also designed with an attractive asymmetrical appearance that allows users to utilize any front RAM slot without restriction. This is fantastic because many coolers may obstruct the use of RAM slots. The cooler itself is only 155mm tall, so it will fit in most PC cases on the market.

For a budget-type cooler, the Scythe Fuma 2 surely does a fantastic job. It’s good for people who just want to get a decent cooler without spending too much.


Vetroo V240 – Affordable AIO Cooler

Vetroo V240

Vetroo might not be a well-known brand to many, but the company offers quality products at affordable prices. One of the best examples is the Vetroo V240, which provides excellent cooling performance for its price.

The V240 is an all-in-one liquid cooler that will definitely keep the Core i5-11600K running at optimal temperatures. It has a 240mm radiator with high-density aluminum fins that are intended to enhance heat dissipation and circulation. It also comes with dual PWM fans that can automatically adjust their speed to match the CPU’s temperature. This results in better airflow and lower noise operation. Furthermore, it must be configured in the BIOS to operate in PWM mode. In this case, the fans will run at full speed if the PWM setting isn’t changed.

Aesthetically wise, both the pump and fans come with addressable RGB lighting. It has a 5V 3pin connection that allows it to connect with the motherboard for uniform and rich illumination. There is also an included controller for easier control over the lighting and fan speed settings.

Noctua NH-U12A chromax.Black – Low Noise Yet Powerful

Noctua NH-U12A chromax.Black

If you want to achieve both soundless and great cooling performance, then the Noctua NH-U12A is your best choice.

It is a 120mm single-tower heatsink with 7 heat pipes that help to distribute the heat evenly, and with its increased fin surface area, it is able to dissipate more heat than a traditional cooler of the same size.

The fans that come with the Noctua NH-U12A chromax.Black are the NF-A12x25 120mm fans, which are known for their low noise yet great cooling performance. They come with Low-Noise Adaptors and PWM for automatic speed control, so you can get the full cooling performance under load while keeping the noise levels at a minimum. The NF-A12x25 120mm fans are able to achieve up to 102.1 m³/h of airflow, and with the Low-Noise Adaptors and PWM, you can keep the noise levels at a minimum (18 dB). Additionally, the MTTF of the NF-A12x25 120mm fans is over 150,000 hours, so you can be sure that they will last for a long time.

CPU coolers for the Core i5-11600K Buyer’s Guide

LGA 1200 Compatibility

Before buying a cooler for your Core i5-11600K, you need to make sure that it supports the current socket of the CPU. In this case, it’s LGA 1200. Not all CPU coolers are compatible with LGA 1200, so be sure to check it before buying. However, all aftercoolers that are mentioned in this article are compatible with the LGA 1200 socket, so they will work out-of-the-box.

Air Cooler or AIO Cooler?

They both have advantages and drawbacks. Air coolers are cheap, easy to install, and do not make any noise. But they may not be as effective as an AIO Cooler does. Though there are air coolers out there that can match up the performance of an AIO, NH-D15 for example, still the majority of the air coolers do not stand a chance against the AIOs. An AIO cooler on the other hand is more expensive but it’s also completely silent and has better cooling performance.

We can say that choosing between air and AIO cooler is completely a matter of personal preferences.


Conclusion

As you can see, there is a wide range of CPU coolers on the market for Core i5-11600K. Whether your goal is to overclock or just want to achieve optimal cooling, there are many options available and this list should help you get started with choosing one that fits your needs best.
