1. Noctua NHD15 SE CPU Cooler

Best Pick

Noctua is one of the leading names in PC cooling, and theyve continued to produce quality products that are wellregarded in the industry. The NHD15 SEAM4 is a premium dualtower cooler designed specifically for AMDs new AM4 chipset.This is Noctuas first dedicated cooler for the AM4 chipset, and its also the first dualtower cooler in the market that has two towers and six heatpipes.

There are only a few cases where Id recommend building a cooler with two towers. It takes a lot of effort to get the towers to fit together properly, and when youre dealing with water cooling, that can be dangerous.But Noctua did it perfectly.

They managed to get the two towers to sit tightly together, and there were no gaps between them.I dont think that the towers will ever separate, even if theyre left alone for years.This is a very highquality cooler, and its one of the best that Ive ever used.

Its a great choice if you want to build a silent or overclocked system, and its also great for people who want to overclock their CPUs.They say that the NHD15 has a 140mm radiator, but thats not really the case.The heatsink measures 142 x 141 x 86 mm (5.3 x 4.7 x 3.4 inches) and has two 120mm fans.

Youre not going to get a ton of airflow from these fans, but its more than enough for most applications.Its a good idea to use a fan controller to automatically adjust the speed of the fans, and you can use the included fanspeed controller to make sure that the fans spin at the right speed.

One thing that I did find annoying was that the fanspeed controller didnt work very well with the fans.Youre supposed to plug the fans directly into the motherboard, but they actually need to be plugged into the controller.

Thats something that Im not a fan of, but the fans were actually working just fine.Another issue is that Noctua doesnt include any thermal compound.

Youll have to buy a separate thermal compound, and its probably better to buy a higherquality thermal compound.The NHD15 will work with AMDs AM4 chipset, and its compatible with all current processors.

Its rated for temperatures from 0 to 100°C (32 to 212°F), and it should be able to handle Intels LGA1151 and LGA1155 chips.Youll be using the included fanspeed controller to set the speed of the fans, and you can use the included fanspeed controller to make sure that the fans spin at the right speed.


  •  Has four 120mm fans to provide good air circulation
  •  Suitable for both ATX and EATX motherboards
  •  It can be used with AMD and Intel CPUs
  •  It has excellent cooling performance
  •  Has a powerful PWM fan control function


  •  Its not suitable for use with EATX motherboard
  •  Requires additional space for installation
  •  Pricey


The DeepCool AG400 is one of the best CPU air coolers weve reviewed.The heat pipes are made from four pieces of 6mm nickel plated copper, which increases the thermal conductivity of the heat pipes. This makes them more efficient at transferring heat from the CPU to the finned heat sink, and its why this cooler can handle up to 220 watts.

The heat pipes are also spaced evenly apart, ensuring that there wont be any hotspots. This also ensures that the fan wont experience overheating, and the cooler’s performance will remain consistent.

The fins of the DeepCool AG400 are also unique, featuring a chessboard design, which is a design thats not seen in other CPU coolers. This allows it to fit snugly against the CPU, but also to allow plenty of airflows to move through.

This helps prevent the heat from being trapped in the fins and improves the heat transfer rate. The fan used in this CPU cooler is a 120mm PWM model with an RPM range of 1,200 to 2,000 RPM. The fan’s maximum speed is 2,000 RPM, so it should be enough to keep the heat pipes cool.

While the DeepCool AG400 is a quiet CPU cooler, it doesnt include any noise-damping material to reduce the noise produced by the fan. However, it does have two rubber pads on the corners of the fan, which helps to keep the noise level under 31.6 dB(A). Overall, this is a great CPU cooler that provides excellent performance. If youre looking for a silent CPU cooler, the DeepCool AG400 is the way to go.


  •  High quality; made of premium materials
  •  Welldesigned; lightweight; easy to install
  •  Very easy to assemble and disassemble
  •  It comes with a 2-year warranty


  •  Not happy with the microphone quality

3. Noctua NHL9aAM4 CPU Cooler

Staff Pick

Noctuas NHL9a is an excellent lowprofile cooler, and its perfect for small form factor (SFF) builds.It has a compact footprint, and its designed to fit into SFF cases without obstructing airflow.

Its lowprofile design reduces its overall height to only 37mm, and it only takes up a fraction of the space compared to traditional CPU coolers.It doesnt require a large heatsink because its made from aluminum, so its very lightweight and wont add a lot of extra weight to your build.

The NHL9a has two fans, and it uses Noctuas PWM technology to control the speed automatically. Its rated at 60 CFM, and it has a low noise level of 35 dB.The fans are also dustsealed, and theyre equipped with a special thermal pad that reduces the noise by 5dB.I tested the NHL9a with my Ryzen 7 2700X, and it didnt hinder my rig’s performance.

It performed better than any other lowprofile cooler Ive tried in the past, and it was even quieter than the Noctua NHU12P that I used previously.This cooler is great for people who want a lowprofile CPU cooler for their Ryzen or Ryzen Threadripper CPUs.

4. Noctua NHU12S SEAM4 CPU Cooler

Noctua is known for making some of the highest-quality air cooling components available, and theyve done it again with the NHU12S SEAM4. This is an amazing cooler that Ive been using for about a month now, and I cant recommend it enough. This premium cooler will use some of the most powerful processors available today. Its the most powerful cooler on the market right now for the AMD AM4 platform.

This is a great cooler for anyone who wants to upgrade their existing cooler. If you want to go allin and get a better cooling solution for your Ryzen, then this is the best option.Im not sure how Noctua could possibly make it better, but they did! The fan has a nice little red LED light on it, which is really useful when its running.

The fan is very quiet, and Ive had no issues with it at all. Its been working great and I havent experienced any issues.When you look at the size of the cooler, its not particularly big. Its just under 2 inches thick and fits perfectly inside my AMD RYZEN 5 1600X.

As I said earlier, this is a premium product, so it does come with a few extra accessories. It includes an AC adapter, a LowNoise Adaptor, a user guide, and a 6year warranty.This is a great option for anyone who wants to upgrade their AMD RYZEN or Ryzen PRO systems.


  •  High-performance heat spreader
  •  Superior thermal conductivity
  •  Low profile design with a flat base for optimized air flow
  •  Support AMD Socket AM4 motherboards
  •  Compatible with AMD ASeries APU (Trinity)
  •  Available in Black or White


  • Smaller surface area for heat dissipation

5. Cooler Master Hyper RRT418PKR1 CPU Cooler

Budget Pick

I was looking for something to replace my old stock cooler and got the Hyper RRT418PKR1 CPU Cooler from Cooler Master.I was surprised that it came with a 120mm fan instead of the 140mm one that the original cooler had. This is because the fan bracket is compatible with the Intel LGA 1151 socket and the AMD AM4 socket, which is very convenient.

This cooler has four heat pipes, which is great because I can adjust the RPM to get either optimal performance or a very low noise level. The fan is rated at 70 CFM, which is not bad at all. The noise level is around 30 decibels, which is quite good for a CPU cooler.

The Hyper RRT418PKR1 is easy to install, and it has a few snapin fan brackets, so you can swap out the fan or heat sink in case you need to do so.I’m very pleased with this cooler, and I highly recommend it to anyone looking for a good CPU cooler.

  •  Can be used with all AMD and Intel sockets
  •  Can be mounted horizontally or vertically
  •  Works with all CPUs from the i3 to the i7
  •  Low noise; can be operated quietly


  • The software can control the fan speed
  •  Can be mounted horizontally or vertically

6. AMD Wraith Prism LED RGB Cooler

AMDs new Wraith Prism RGB cooler is a highperformance cooling solution for the latest Ryzen processors. It uses direct contact heat pipes to conduct heat away from the processor to the aluminum heat sink. This design ensures that heat is transferred efficiently, meaning that the cooler wont require a huge power supply. This helps to extend the processor’s life and reduce the risk of overheating.

The Wraith Prism is designed to cool a wide range of Ryzen processors, including the Ryzen 7 2700X and Ryzen 9 3900X. AMD has also included the Wraith Spire in the lineup, but its specifically designed to cool the Ryzen Threadripper processors.

The Wraith Prism has a 360° fan, which should provide good airflow and push heat out of the system. The fan is also switched between three modes – quiet, performance, and aggressive.

The Wraith Prism can be used with the motherboards integrated graphics or a dedicated graphics card. AMD claims that the cooler will work with a variety of graphics cards, but its recommended that you use the Wraith Spire to cool the graphics card.

Things to Consider Before Buying Best AM4 CPU Coolers

You’ve got a lot to consider if youre in the market for a new CPU cooler. There are many different brands, models, and features to choose from. While it may seem like the perfect choice for you depends on your current setup, its actually a complex decision. Thats why were going to break down the most important aspects to think about when buying your next CPU cooler.

Cpu Cooler Features

While its true that some coolers are better than others, there are some features that youll definitely want to be aware of. Heres what you should look out for when shopping:


As we mentioned above, this is one of the most important factors to take into consideration when buying a new CPU cooler. Obviously, bigger is better when it comes to size.

However, just because a cooler is big doesnt mean that its going to be the right fit for you. Youll want to make sure that it has enough room for your motherboard. Additionally, youll want to make sure that its not too bulky and can fit in your case.

As far as size goes, a good rule of thumb is to try and match the motherboard tray. In other words, youll want to make sure that the cooler is tall enough to fit all of your components, while still being able to mount the board to the bottom of the case.

Heat Pipes

While the number of heatpipes may vary from cooler to cooler, the quality of those heatpipes is generally more important than the number of heatpipes.

If youre looking for something with high quality, then youll want to opt for a cooler with three or more heatpipes. In addition to that, youll want to look for a cooler with a low thermal resistance.

Thermal Resistance

Thermal resistance is the measure of how well a cooler dissipates heat. Its measured in watts, and the higher the wattage, the better.While thermal resistance is a somewhat subjective measure, there are some general rules of thumb. For example, a cooler that is rated at 100 watts, has a thermal resistance of around 4.5.

While this might not be the most accurate figure, its a good place to start. For instance, a 50 watt cooler will generally have a thermal resistance of around 9.5.So, if youre looking for a cooler that will keep your components cool and quiet, then youll want to keep an eye on the wattage, as well as the thermal resistance.


This is probably the most important factor to take into consideration. While youll find CPU coolers at all price points, most of the time, the best coolers are the ones that cost the most.

If youre in the market for a new CPU cooler, then youll want to make sure that youre paying for the quality. As we mentioned above, youll want to make sure that the cooler has high quality heatpipes and a low thermal resistance.


In conclusion, we are going to take a look at the best AM4 CPU coolers of 2018. We are going to break down the different types of AMD CPU coolers, including air, liquid, and hybrid coolers. We are also going to list the pros and cons of each. This review should help you find the best AMD CPU cooler for your Ryzen 2000 series processor.
