8 Air Coolers tested on AMD Ryzen – May 2024

Lately we have been inundated with CPU air coolers to review, but to do individual reviews of them all would take the best part of the next few months – so like we did recently in our AIO cooler roundup, this article will be in a similar format but looking at a bunch of new air coolers and testing their performance against some well-known opposition. So now you know what this is all about, let's take a quick look at each of these coolers and get on with some testing.

In this multi-review, we take a look at several recently launched CPU air coolers. We split them into two categories for testing, to give the smaller coolers a fighting chance they are tested on a new Ryzen 5 7600X test system while the larger dual tower coolers are tested on our current AIO cooler Ryzen 9 7950X test system.

We've rounded up all the specs, features, and the usual pro's and con’s, as well as the performance charts below for you to browse through. However, if you want to see the coolers in all their glory make sure you check out the video in the YouTube link at the top of this page. There's a lot to get through so let's get cracking.

Testing Methodology:

We are primarily focussing on the performance of each cooler at 100% fan speed and also when locked to 40dBA noise output. We will focus on cooling performance using a manual overclock with all-core frequency and VCORE locked and Precision Boost Overdrive performance.

• The test data is logged using HWINFO and the final 10 minutes of the data is calculated to find the average CPU temperature and CPU clock multiplier (PBO Test) and then plotted in the charts.
• For testing, we use a 30-minute looped run of Cinebench R23 and record the steady-state CPU temperature at the end of the test. This ensures that the CPU has had ample time to warm up and reach a steady state under all of the coolers.
• The ambient is maintained at 19-21 degrees Celsius. Where there is variation beyond this temperature range, we add extra repeated tests to ensure consistency. However, this is well controlled now with A/C.
• We also test each cooler with at least two fresh installs (typically three) to mitigate the likelihood of poor mounting spoiling results.
• Ambient temperature and humidity are controlled via a mini split air conditioning system inside the test room. Ambient temperature is maintained between 19-21C, Temperature delta figures are shown in the charts (ambient temperature is deducted from the measured component temperature).

Test Results: AMD Ryzen 5 7600X

Acoustics

Let's take a look at the performance of the smaller coolers first and start by looking at noise output as this gives us a good indication of performance based on noise.

With just one fan running at maximum speed the Arctic Freezer 36 is the quietest out of all, just edging out the Noctua NH-U12S. The U12A with one fan, the Freezer 36 with two fans, the Endorfy Fera 5 and the Cooler Master Hyper 212 are close behind.

We added the Cooler Master Hyper 622 to the smaller cooler tests due to its performance on the higher power system, you will see why later.

Thermal Performance

With all coolers running at maximum fan RPM the Arctic Freezer 36 (Two Fans) produces very impressive thermal performance, at 30°C over ambient it matches the much larger Cooler Master Hyper 622 while running slower fan speed and with much lower noise output.

The Freezer 36 also trades blows with the much more expensive Noctua NH-U12A with both fans running at maximum speed. However, the Endorfy Fera 5 is just 1°C over ambient higher while using just one fan, which is equally impressive. However this test is only a thermal load of approximately 50 Watts, the PBO test later will be double the thermal load.

Still with the CPU at a fixed frequency of 4.7GHz and locked voltage, we limit the fan noise output to 40dBA and run the same thermal load test again.

Results are very similar as most of the coolers don’t exceed our 40dBA limit at max fan speed, but it is worth pointing out that the Arctic Freezer 7 X which only uses a 100mm fan and a smaller heat sink, isn’t far off the performance of the Cooler Master Hyper 212 which uses a larger heatsink and bigger 120mm fan, which is disappointing from the Hyper 212.

In the PBO test the important metric is clock speed, the thermal load in the PBO test is doubled from the previous test at around 100W.

The larger coolers such as the Noctua NH-U12A, DeepCool AK500 and the Cooler Master Hyper 622 Halo are expected to do better in this test so it's no surprise to see them topping the charts with the higher clock multiplier.

But again it's very impressive to see the Arctic Freezer 36 (Two Fans) holding the same average clock multiplier as the much bigger and louder Cooler Master Hyper 622. It is astonishing to think that this cooler can be purchased for around £20 currently which is more than half the price of the Hyper 622 but thermal performance is equal.

The Endorfy Fera 5 again shows great performance in this test with a clock frequency to match the larger and more expensive coolers but the Cooler Master Hyper 212 Halo is rather disappointing considering it’s running a similar size heatsink and 120mm fan like the Fera 5.

Test Results: AMD Ryzen 9 7950X

Acoustics

Again looking at noise levels first with the dual tower coolers, the be quiet! Dark Rock Pro 5 lives up to its name with low noise output at maximum fan speed, but it is a couple of dBA louder than the outgoing Dark Rock Pro 4, which is noticeable but still very tolerable.

The two larger fans running at higher speeds of the Dark Rock Elite increase noise output by another 4dBA, which starts to become more noticeable in an open frame chassis, but by far the loudest of the dual tower air coolers that we tested is the Corsair A115 at 51dBA, which makes it considerably louder at maximum fan speed than some 360mm AIO liquid coolers.

Running maximum fan speed tests the cooler's raw thermal performance. The Corsair A115 converts its high fan speed and high noise output into good thermal performance at max fan speed but it’s the two be quiet! coolers that impress the most here. Both are considerably quieter than the Corsair cooler but they match the A115 in performance at maximum fan speed.

What's even more interesting is that the Dark Rock Pro 5 almost matches the performance of the Elite while having a smaller front fan running lower RPM and quieter, which seems to point that be quiet! has a very efficient heatsink design.

The performance of the Cooler Master Hyper 622 Halo is disappointing, to say the least.

Tuning fan speeds to 40dBA creates a level playing field as it stops any cooler from brute forcing its way to top performance by using high fan speed with lots of noise.

But pegging both of the be quiet! coolers back to 40dBA noise output reaffirms their claims as top performers as both the Dark Rock Elite and Dark Rock Pro 5 are the top performers of all the dual tower coolers which is very impressive.

The Corsair A115 matches the legendary Noctua D15 performance at 40dBA which is good but the D15 has been around for a long time and its due to be replaced soon with a new revision.

The performance of the DeepCool Assassin 4S is OK considering it only has a single fan but again it's quite a poor showing from the Cooler Master Hyper 622 Halo.

In the PBO test the important metric is the clock multiplier, as the CPU adjusts clock speed based on a target temperature so the CPU temperature between coolers will be very close.

The top AIO liquid coolers produce the best clock multiplier in the PBO test but as we saw in the noise normalised test both of the be quiet! coolers are next in the chart giving a fractionally higher clock multiplier than the other air coolers.

The Corsair A115 can claw back performance in this test as it uses its brute force high fan speed to cool the CPU again, giving it a slight clock speed advantage over the Noctua NH-D15, but the lowest clock speeds are from the single fan DeepCool Assassin 4S and the Cooler Master Hyper 622 Halo black.

Discuss on our Facebook page HERE.

KitGuru says: We are very impressed by the low noise output and excellent thermal performance from both be quiet! Dark Rock coolers, however, the Elite can be a little expensive so it's worth shopping around for that one. The Endorfy Fera 5 black is a solid choice but the best performance and value choice has to be the Arctic Freezer 36.
