Noctua is renowned for its quiet cooling fans, and their flagship NH-D15 is no different. It has two superior NF-A15 140mm fans with PWM support, providing automatic speed control that raises its efficiency.

These fans also provide extensive airflow to their surrounding components which is why NH-D15 ranks highly in terms of individual component cooling.

This time around, Noctua installed the heat pipes further apart, thus allowing the fan to distribute the thermal load equally and over a spread-out surface. Unlike other conventional fan coolers, the NH-D15 also has a dual tower design with a six-heat pipe installment that will cool the system much faster.

For easy application, the cooler comes with a thermal solution that is reliable and long-lasting, making the NH-D15 ideal for anyone who wishes to use water cooling for their PCs. It’s available in two colors; a dark beige-brown, and a pitch-black (not a lot of variety). With a six-year warranty, the NH-D15 is a great investment for a quiet and efficient cooling of your Ryzen Zen 3 build.

If you’re looking for a cooling fan that provides optimal cooling performance but doesn’t empty out your pockets, then the Mugen Rev B is a good purchase. It uses the Kaze Flex series for higher stability and performance, and is equipped with a PWM fan that can provide speeds up to 1200 RPM.

The design of the Scythe Mugen 5 Rev B uses a copper base plate and places the 6mm pipes along a slight gradient for efficient heat distribution. It also has a special oil film covering that reduces friction and vibrations, contributing to a long lifespan. 

The Hyper Precision Mounting system also allows easy installation, and if you need extra cooling, the Mugen Rev B also offers space to mount a second fan. This revised CPU cooler is compatible with AM4 platform, so you’re all set for either AMD Ryzen 7 3700x or Ryzen 7 3800x.

We’re in the big leagues now! Durability, ultra-quiet performance, and a high-quality build are just some of the features that you get with the Dark Rock Pro 4! It provides a TDP rating of 250W, which means you can have hardcore gaming for long hours while the cooler maintains the temperature of the CPU.

The six-pole motors and sophisticated aerodynamic design optimize airflow, and the Silent Wings 3 provides a high level of air pressure in order to evaporate heat efficiently.

Builders who are fans of quiet rigs will also be happy to know that even at maximum performance, the Dark Rock Pro 4 has a mild noise that’s just 24.3 dB(A).

This model is built with seven 6mm heat pipes and uses ceramic particles that allow quick heat transfer across the surface area and aids in the evaporation.

Be Quiet has also been innovative this time by including small dots on the surface of the cooling fins, which is an impressive way to improve air circulation without including any other parts.

The fan cooler integrates an array fin design with plenty of headroom for RAM clearance. 

The Dark Rock Pro 4 also owes its popularity among gamers to the black aesthetic that so many people find attractive. The jet-black color coupled with the aluminum brushed cover gives off an elegant vibe, an aesthetic that many gamers are after.

Considering Noctua’s experience with CPU coolers, it’s no surprise that their name appears twice on our list. The NH-L12S is quite subtle, so if you want the job done without buying anything flashy, then Noctua has you covered.

The cooler has a slim 120 mm PWM fan and is stalled below the fins, which means that the height of this cooler is just 70mm. Gamers also get an option to install an additional 120x55mm fan if they wish to get extra cooling.

Accompanied by the NM-I3 mounting kit, this cooler has an easy installation process for an mITX build. It also comes with a thermal solution designed to provide minimum friction to elongate the cooler’s life.

It looks like Noctua really believes what’s on the inside matters because the NH-L12S like the NH-D15 is more focused on performance than appearance. The cooler is a dull brown cooler, which may interfere with certain builds.

When it comes to liquid coolers, the CORSAIR H100i really steals the show. Sporting two 120 mm magnetic levitation PWM fans, this cooler can deliver speeds up to 2400 RPM and has a flawless airflow system with a silent operation that guarantees a cool CPU. Along with this, the H100i also has a 240 mm radiator with a broadened core that helps disperse the heat faster.

For this model, CORSAIR decided to use a cold plate and low-noise pumps that perform even when you overclock your system to the maximum. The Zero RPM technology also stops the fans completely at low temperatures, which contributes to the cooler’s durability. The mounting bracket that comes with the cooler also makes it very easy to install, saving you time and effort.

There’s also good news for the aesthetic builders! The Corsair H100i has 16 addressable RGB LED lights that can be synchronized with the rest of your system, and help you get that color coordination.

One look at this design is enough to convince you to buy this! The cooler reportedly went under a thorough designing process, and the results are impressive. It has a PWM controlled pump that has an exceedingly low noise level even during peak performances and consumes very little power. With a TDP of 200W, it can dissipate thermal build up incredibly fast, making it the ideal choice for build with either Ryzen Zen 2 or Zen 3 series.

The cooler consists of dense 38mm thick radiators and this allows for more water to flow through and cool the system. The fan is slightly diagonal and just 40 mm in size and operates without a sound (we know small fans are notorious for being noisy, but this one really proves itself).

The Liquid Freezer series is renowned for its compatibility with a range of systems, and the clean-cut look thanks to the tubing design makes the cooler the first choice on the market for the Ryzen 7 3700X.

However, if you want a perfect blend between CPU cooling performance and aesthetics, NZXT Kraken Z63 with it’s customizable LCD display and two PWM fans ticks all the right boxes.

In the AIO cooling system, it’ll be hard to find a better cooler than the S36 Prisma! This has everything you need, from geometrically designed fans for better airflow to LLS (Long Life Sleeve) fan bearings that allow it to work quietly. It boasts rotational speeds up to 2000 RPM, and has PWM control so once you’ve installed it, you won’t need to take care of anything else!

For distribution, the S36 Prisma has all the fan connections leading directly to the radiator, and this exudes a clean and fresh look with any loose wires hanging out. All the wires are tied in braided sleeves, also protecting them from any external damage.

The most popular reason why gamers love to invest in this cooler is because of how user-friendly it is. Firstly, the thermal paste for installation is pre-applied, thereby making it easy to install and a mess-free process. Secondly, the glass face featuring the backlit logo and addressable RGB LEDs means that it’s a great investment for people who want a fashionable cooler for their build.
