The Noctua NHD15 is a great CPU cooler that can handle highperformance CPUs like the Intel Core i9. Its a successor to the popular NHD14, so it inherits its features. This means its designed for maximum compatibility with Intel CPUs.

The heat pipes are made of copper and nickel, and two fans are included. They run at low speeds and are pretty quiet, so its perfect for silent computing or overclocking.

The Noctua NHD15 can handle highperformance CPUs like the Intel Core i9. The heatsink is pretty large, which is great for bigger CPUs. It comes with two 140mm fans and a nice NTH1 thermal paste.

The heatsink is constructed with a dual tower design, ideal for better heat dissipation. A good amount of copper and nickel is also used in its construction. The Noctua NHD15 is the best CPU cooler Ive ever used for my Intel Core i9. Its super silent, and it performs well too.

It can handle any CPU, and its performance is excellent. Its also super easy to install. You can get this for $40 more than the Noctua NHD14, but thats the price of a great cooler.


  •  Suitable for only Intel sockets
  •  Some have complained that this cooler has a low cooling capacity
  •  It has a plastic top cover
  •  It can only be used with Intel sockets

2. Corsair H150i Pro

The Corsair Hydro Series H150i PRO RGB AIO Liquid CPU Cooler is one of the best cooling solutions for enthusiasts, featuring RGB LED lighting that can be customized to match your build.

There are two main advantages of this cooler, the first being the RGB LED lights. These allow you to customize each color’s color, intensity, and placement and make the cooler pop.

The second advantage is that the pump head is designed to produce a lot of airflows, which is ideal for todays CPUs. The H150i has a radiator with a 360mm x 90mm design, which is a decent size.

The pump head can produce 47.3CFM of airflow, which is great. However, the fans themselves arent the best. The Corsair Hydro Series H150i features three 120mm ML series PWM fans, which are low-noise fans that are good for quiet operation.

The fans can produce up to 25.0 dB of noise, which isnt very loud. However, the noise increases when the fans are set to full speed, so keep the fans at minimum speeds.

The Corsair Hydro Series H150i is compatible with both Intel and AMD processors. You can also use the Corsair iCUE software to control the RGB LEDs, monitor the temperature of your CPU, and even set the pump head to zero RPM mode.

The Corsair Hydro Series H150i is one of the best liquid CPU coolers on the market. The RGB LED lighting is fantastic, and the pump head provides great airflow.

The Dark Rock 4 is also a great option for overclocking, and its six highperformance copper heat pipes can disperse heat efficiently.

The Dark Rock 4 supports 120mm fans, but there are a few limitations. It can’t support 240mm fans or any other type of fan that isn’t PWM. The size of the mounting hole is also small, so a larger fan will be difficult to mount. However, if you’re looking for a quiet and efficient CPU cooler, then the Dark Rock 4 is a good option.

Thing To Consider Before Buying

The i99900K processor is among the top-of-the-line, and when it comes to cooling, we’ve found some key things to consider.


First, the price will be the first thing you need to look at. The average retail price for the i9 9900K processor is around $360.

If you’re looking to build a high-end gaming PC, you can expect to pay much more for a processor of this caliber. For the same price as a 9900K, you can get an Intel Core i79750H processor, which would be considered midrange.


Next, you need to look at the features of the processor itself. A few of the most important are listed below.

Core Count

The processor’s number of cores is one of the most important factors to look at when shopping for a CPU. This will determine how many threads the processor can handle, and it will also impact how fast the processor can run.

The more cores, the better.

When shopping for a processor, you can look at the core count and see what it is. For example, if the processor you’re considering has eight cores, you can get a rough idea of how powerful it is.

Cores Per Socket

The second most important thing to consider is the processor’s number of cores per socket.For example, an Intel Core i9 9900K has a base core count of 20 cores per socket, while an Intel Core i79750H has 18.

The latter is a better value, but the former is a much more powerful processor.

Base Frequency

The base frequency of the processor is the processor’s speed, which can be seen on the specifications. The base frequency is the speed of the processor when idle.You can also see the base frequency in GHz, and this is how you can tell the difference between the 9900K and the 9750H.

The base frequency of the 9900K is 3.1 GHz, while the base frequency of the 9750H is 3.2 GHz.The 9900K is faster, but if you’re building a gaming PC, the 9750H is a better value.

Turbo Boost

  • The third most important factor to consider is the turbo boost.
  • This is the maximum speed of the processor, and it will depend on the core count and base frequency of the processor.
  • For example, the base frequency of the 9900K is 3.1 GHz, while the 9750H is 3.2 GHz.
  • So if the 9900K had a turbo boost, it could go to 4.3 GHz.
  • The turbo boost will vary based on what motherboard you have installed.
  • Intel Core i9 9900K vs. Core i79750H
  • The Intel Core i9 9900K is a better processor than the Intel Core i79750H.
  • The 9900K has a core count of 20 cores, while the 9750H has a core count of 18.
  • The 9900K has a base frequency of 3.1 GHz, while the 9750H has a base frequency of 3.2 GHz.
  • The 9900K is a better value, but the 9750H is still a good processor if you’re looking for midrange performance.


If you buy a CPU cooler, you want something that can keep your i9 9900k cool for long periods. The best thing you can do to ensure that is to pick a CPU cooler with a fan. If you are looking for the best CPU Cooler for the i9 9900k, I suggest you buy the NZXT S340, a high-end CPU cooler with a 360mm radiator. Its the best CPU cooler for 9900k.
