Best CPU Coolers for Ryzen 7 3700X

Ryzen 7 3700X and Ryzen 7 3800X are set to hit shelves across the country on July 7th, and with this release many AMD builders, first time or seasoned, will be looking to build their Ryzen 7 3700X/3800X system – whether it be a high-end, mid-level, mini-ITX, micro-ATX or ATX 3700X build.

Whatever your type of Ryzen 7 3700X build, to get the most performance out of your system, you need to pick carefully which components you will want to pair with this Zen 2 processor – to maximise cooling performance as well as other factors such as noise reduction and even aesthetic of your Ryzen 3000 build. Early rumours are coming out that the Ryzen 3000 series with the stock Wraith cooler will run pretty toasty, so if you are looking to make one upgrade to your Ryzen Zen 2 system to maximise performance, we recommend that being the CPU cooler.

In this particular guide, I will show you the best CPU coolers, air and AIO/liquid, to pair with the Ryzen 7 3700X or Ryzen 7 3800X for a variety of different builds, such as the best SFF cooler for mini-ITX Ryzen 7 3700x builds, or perhaps the best cooler for overclocking Ryzen Zen 2. Note, for a CPU cooler to be compatible with the new Ryzen Zen 2 processors, you will have to make sure it uses the AM4 socket – since Zen 2 compatible chipsets such as the X570 motherboards utilise the AM4 socket.

This is a successor article to my Ryzen 7 2700X cooling guide, so if you are still planning to build with the Ryzen 7 2700X – then i recommend also checking that out.

As usual, any questions or comments about my CPU cooler selections for the 3700X and 3800X, or want to ask something I may have not covered – let me know in the comment section below! Enjoy.

Noctua NH-D15 – Best Air Cooler for 3700X

noctua-nh-d15-se-am4

The Noctua NH-D15 is hands down the best air cooler on the market for the Ryzen 7 3700X and 3800X in 2020, and we don’t expect that to change anytime soon.

A successor to the hugely popular NH-D14, this dual-tower design air cooler has dual 140mm fans and offers cooling performance comparable to a 280mm AIO liquid cooler. In addition to the cooling performance, the fans are super silent in operation making this an ultra-quiet CPU cooler for Ryzen 7 3700x builds.

Before 2020, this CPU cooler wasn’t compatible with the AM4 socket, but thankfully now it is possible to mount some of the older NH-D15s or even non-AM4 versions using Noctua’s official AM4 mounting kit, the NM-AM4 mounting kit, by ordering it here from their official website.

The NH-D15 has a height of 160mm, so it’s certainly not the smallest cooler – but we recommend if it fits in your 3700X or 3800X build then go for this cooler.

If the colour scheme isn’t for you, you’re in luck – with Noctua announcing a new sleek black version of the D15s! Alternatively, the Dark Rock Pro 4 is a common option for those who don’t like the color scheme but want a comparable performance to the DH15 for Ryzen 3700X and 3800X systems.


Scythe Mugen 5 Rev B – Best Budget Cooler for 3700X

scythe-mugen-5-rev.b

The Scythe Mugen 5 Rev.B. is my second recommendation for cooling the Ryzen 7 3700x – this is a very capable air cooler that goes toe-to-toe in performance with the Noctua NH-D15, and features a more understated clean design. This cooler will certainly be capable of overclocking the Ryzen 7 3700X and even 3800X without issue.

Being a bit smaller than the Noctua NH-D15s height at 154.5mm, this will be slightly more compatible with more PC cases used for Ryzen 7 3700X builds – but still will be slightly too large (in most cases) for small form factor Zen 2 setups.

The Mugen 5 Rev.B. is the cheapest CPU cooler for the Ryzen 7 3700x on our list at just under $50, making it our recommended CPU cooler for budget Zen 2 builds.

The Mugen 5 Rev.B. sure makes for a great upgrade over the stock Wraith Prism 3700X cooler in 2019.


Be Quiet! Dark Rock Pro 4

The Noctua NH-D15 and Be Quiet! Dark Rock Pro 4 are two coolers that are often compared against each other due to their similar, excellent levels of thermal and noise performance – even comparable to the performance of a 240 or 280mm AIO cooler!

With a TDP rating of 250W, the DRP4 can handle any of the Zen 2 CPUs, and with its seriously impressive cooling performance, it will be able to handle high overclocks for the Ryzen 7 3700x and 3800X without issue – given your case has decent airflow.

The Dark Rock Pro 4 will be a great candidate for an ultra quiet Ryzen 7 3700X/3800X build – with two 140mm PWM fans offering virtually silent operation.

If the Noctua’s color scheme isn’t for you, or you want to have a great-looking, sleek CPU cooler whilst offering best-in-class performance, the Dark Rock Pro 4 gets our recommendation for cooling the Ryzen 7 3700X and Ryzen 7 3800X in 2019.


Noctua NH-L12S – Best Low Profile Cooler for Ryzen 7 3700X / 3800X SFF Builds

Noctua-NH-L12S

All CPU coolers mentioned in this list so far are for regular ATX or mATX builds, and most will not be suitable or have enough clearance for mini ITX and small form factor (SFF) Ryzen 7 3700X builds.

Our recommended low profile cooler for the Ryzen 7 3700X and 3800X, coming in at 70mm height, is the Noctua NH-L12S. This CPU cooler offers fantastic cooling performance for such a small package, and really has a nice solid, premium feel to it. A slim 15mm 120mm PWM fan is included with the NH-L12S – and like with most of Noctua’s air coolers, offers virtually silent operation even at high CPU load.

If you’re looking to do an ITX Ryzen 7 3700X build, you may also be interested in our X570 Mini ITX motherboard comparison, as well as our favorite ITX cases for SFF builds in 2019.
