PBO Performance and maximum noise levels
We’re going to start this review’s benchmark section by focusing on a traditional maximum performance test, with the CPU cooler’s fans allowed to reach their fastest speeds, for the best cooling possible.Turning on PBO allows AMD’s Ryzen 9 9950X3D to stretch its legs to an extent and consume over 260W. Enabling PBO incrteases max power consumption and heat output. We use MSI’s X870E Carbon Wifi motherboard, and often the CPU will reach its TJ Max (peak temperature) of 95 degrees C (203 F) and thermally throttle to some extent with most coolers. When this throttling occurs, I’ve measured the average power consumption to determine performance.
High-end AIO liquid coolers, however, are expected to be able to keep AMD’s Ryzen 9 9950X3D under TJ Max during the duration of the benchmark – in these cases, we compare the CPU’s actual temperature.
Today’s review is a bit unique, in that we have the results from a prototype and final version of the AIO being reviewed today – giving us some insight into how these products evolve during the design and manufacturing process.
Both the prototype and retail versions of MSI’s MPG Coreliquid P22 360 handle this test with ease, with an average temperature of 84.7C (184.5F) – one of the best results we’ve seen on this test bench.
Some coolers perform well in maximum-strength tests, but run loudly at full speeds. Noisy fans in this scenario aren’t necessarily a bad thing; some folks prefer to hear them as a way to be aware when the CPU is getting hot.
One issue I raised when I tested the prototype of this AIO was that it ran louder than it needed to. 48.9 dBA is pointlessly loud for most users. MSI took that feedback to heart, and the fans included with MSI MPG Coreliquid P22 360 reach 44.9 dBA at 100% RPM, a moderate volume level that is much quieter than the maximum noise levels of competitor liquid coolers. Those who prefer to implement speed restrictions for silent operation need not worry; our noise-normalized benchmarks show good performance even when the fans are set to run quietly.
200W thermal benchmarks
For the next thermal test, I leave the motherboard settings at their defaults, which results in a power limit of 200W when running Cinebench R23.
In this test, with a standard power limit enabled, MSI’s Coreliquid P22 performs in the middle of the results we have from other liquid coolers – 1.2 degrees C behind our best result, and 3.6 C cooler than the worst result from another AIO.
150W + GPU thermal results, noise levels
Our next test runs Cinebench on the CPU with a 150W power limit, while also running Furmark on MSI’s RTX 4070 Ti Super Ventus 3x OC. This causes the GPU to consume ~295W of power. This test is designed to emulate the thermals of games, which stress the CPU and GPU.
In this test, designed to emulate the thermal conditions of a CPU-intensive AAA game, MSI’s P22 continues to deliver outstanding performance – the result of 37.1 C over ambient (59.1 C actual temperature) is our third-best result, and an improvement of one degree compared to the prototype of this AIO.
Noise-normalized testing
Most testing is performed with the cooler tied to the default fan curve of our MSI X870E Carbon motherboard, but some of y’all prefer to see tests when the noise levels of coolers are equalized. This is especially important to those of you who prefer silent computers. This next test has the CPU cooler noise-normalized to 38.9 dBA, with PBO enabled for the Ryzen 9 9950X3D CPU. Most coolers will not be able to keep the CPU from reaching its peak temperature (TJ Max) in this stress test. So we’ll look at this in terms of average CPU power consumption, which averaged 255.8 watts.
This test is especially difficult, because in addition to the reduced noise from the CPU cooler, our current test bench’s system fans are configured to run extremely silently, below the floor of the noise meter I use to measure dBA.
While I prefer to look at the power consumption in a scenario where the CPU reaches TJ Max (the processor’s peak temperature), I’ve also included the average CPU temperature in the chart below.
Karhu DDR5 RAM thermals testing
Your CPU cooler does not operate in isolation. It has an impact on not just your CPU’s temperatures, but also the other components in your build, like your RAM and GPU. To that end, I’ve run the Karhu RAM stress test. This places a load of ~153W on the CPU and ensures system RAM (DDR5 in my case) is fully stable. In this type of scenario, most AIOs tend to produce worse results than air coolers.
DDR5 temperatures were excellent in this test, on par with ASRock’s Steel Legend, which features an integrated VRM fan. The only result showing better performance is from Silverstone’s IceMyst Pro, with fans that directly cool system DIMMs.
Conclusion
MSI is back in the AIO game with the MPG Coreliquid P22 360. This AIO has a relatively low price tag while featuring a 2.1-inch IPS display, excellent thermal performance, and low noise levels in common scenarios. It’s a solid choice if you’re after a cooler with a round display that cools well. Just note that if you can live without a display, there are excellent options that cost quite a bit less, like Arctic’s Liquid Freezer III Pro, which sometimes sells for less than $85.
