To get most out of this high tech CPU, you need to keep it cool for high-end performance. Suppose you want to upgrade your CPU with RTX 2080 Super with The latest i9 processor for excellent performance and overclocking will end up in overheating. In that case, you need to install a CPU Cooler. You would surely not like to get interrupted because of any reason when you have spent a hefty amount.

To help you all out there, here is a list of outstanding air or liquid CPU coolers to keep the beast in control because the traditional fans cannot handle such tremendous heat generation.

Just to reduce some workload for you, I have decided to pick the best cooler for i9 9900k for you. So you don't have to choose the CPU cooler by turning hundreds of pages. This task is quiet tiring sometimes if you don't have the right guide, but you need not worry anymore since you are on the right page.


1. Analyze your needs:

Make sure to choose the cooler as per your system requirements. In this article, we are talking about the coolers for the Intel i9 9900K setup. So If you gamer or an overclocker, you will surely go for a high-end cooler as it need to fulfill certain benchmark. On the contrary, if you are not into that genre, a simple budget-friendly cooler will work well for you.

2. Air cooler vs. Liquid cooler

The first and foremost thing you need to decide is whether you want an air cooler or a liquid cooler. Air cooler is the most commonly used coolers because of its efficiency and low cost. They use fans alongside a heat sink, and when coupled with a radiator, the cooling system absorbs the heat from the processor and other components that dissipate heat.

Liquid CPU coolers offer better performance when compared to air coolers. They are a lot quieter than air coolers and work more efficiently, making them the best thermal solution for power users and overclockers.

Here it should be understood that while liquid cooling does a great job, it doesn't seem necessary for more basic users.

3. CPU Socket Compatibility

You won't be surprised to learn that not all coolers are compatible with all processors. However, many new builders seem to be making this mistake.

All the CPU coolers for i9 9900k we suggested above are compatible with universal socket LGA 1151. Suppose the cooler model doesn't specify as having a compatible universal socket. In that case, it is important to carefully check its product description or reach out to customer supports service for compatibility information.

4. dimensions

The size and dimensions of the CPU cooler are other important factors to be considered for compatibility. If the cooler dimension is not compatible with your motherboard model or form factor, there might be an inconvenience in fitting into your case.

Air coolers can be bulky, but they are limited to one zone and are not distributed throughout the system. On the other hand, with a liquid cooler, you will need space for the radiator and need to be sure to properly orient and align the CPU water block and the hoses for the coolant.

That said, if you're working on a smaller build, a bulky air cooler might not be the best option. A compact air cooler or an all-in-one with a small radiator might work better. When planning to upgrade, it is recommended to consider a moderate-sized one which fits both mobo and case.

5. Noise Level 

When it comes to air cooler, the larger the fan, the better will be the flow of air. At the same time, the better the fan speed, the louder will be the fan noise. If the fan noise is loud, it will create distractions. Hence it is important to choose an efficient CPU cooler that will offer a noiseless cooling system. Gamers highly prefer low noise or no noise cooling systems. Liquid CPU cooler has an advantage on this factor, as the much quieter when compared to air coolers.

6. Overclocking possibilities

Since the price will be the prime factor, it is worth considering the aims for your build. If you're planning to overclock your i9 9900k, then you will need a high-end CPU cooler.

This discipline is popular with gamers, which allows the processor to work above its maximum capacity. Overclocking is rather water-cooling oriented.

In other words, unless you plan on really pushing the processor, there is no need to go for a Liquid CPU cooler, then there's no sense in looking beyond a quality air cooler.

For those extreme overclockers out there, an AIO liquid cooler is by far the best option, and you may even want to explore open-loop or custom liquid cooling setups. They come with the price tag to match and their fair share of tinkering, but the heat dissipation is unparalleled.


Without a second thought, i9 9900k is one of the most advanced CPU cooler launched in the market to date and with such a high-performance workload, there arises a need for an efficient CPU cooler to keep it running smoothly.

And not to mention finding a perfect CPU cooler for i9 9900k that matched to your needs is quiet a long process  and it requires a lot of time.

To save your time, I have made a lot of effort here to curate this ultimate guide for best CPU cooler for i9 9900k to help out in the task. Though choices may vary with different users, I have enlisted all the highly-rated products here to get all that you require.

You can find the most efficient, quiet working and a budget pick as well in this guide. All you need to do is check all the products and choose the best for you. Good luck!!
