Phanteks P600s Matte White Temp and Noise Tests

A Note on Testing

For our 2022 case testing, we’ve updated our testing thesis and test methods. By selecting a set of air-cooled components that present a very high thermal challenge for cases under review, we have moved away from using thermal probes as a point of comparison.

Instead, our goal is to show whether or not a case enhances or inhibits performance, as well as the thermal and acoustic results recorded during testing.

Our primary focus is on the performance of the installed 2022 Review Rig, and our presented test results are taken under the following circumstances:

  • All stock – CPU defaults on the MSI Z490, three Phanteks case fans
  • Overclocked – CPU set to 5.0GHz, GPU power raised to 150% (315w), three Phanteks case fans

Our tried-and-true loading method is to use a combined load of Cinebench R23 multi-core and the default Furmark GPU stress test. With the CPU overclocked to 5.0GHz and the GPU power and fan limits raised to 150% and 100% respectively, the 2022 Case Review Rig is able to pull a steady 800w at the wall and produces 54dB of noise if all fans are run at their maximum.

How we interpret the results

Things to keep in mind:

  • Lower power usage directly correlates to lower system performance
  • Lower temperatures at the same power usage result from superior cooling

We are admittedly somewhat surprised at the results. While the P600s handled our stock load effortlessly, it did struggle to keep the CPU cool in the overclocked configuration, with our 5.0GHz air-cooled 10900K hitting its 100c limit in Cinebench R23.

Further, despite having the front cover installed to dampen noise, we didn’t see better than average results – and the system only got louder with it removed, but the CPU didn’t get cooler. As adding a fan to the top of the rear would likely increase noise, we opted not to experiment as any conclusion drawn from the resulting data would be fairly subjective given the number of potential configurations.

What we do feel this data shows us is that the stock configuration is sub-optimal for air cooling a hot CPU alongside a hot GPU and that Phanteks’ P600s is really tuned for watercooling either or both sources of heat.
