Practical testing …
Temperature and volume
A Super-Silent PC system is used as the test environment. The reference PC system is neither audible nor measurable in idle. In absolute silence in the room, the measuring device captures 5-7db ambient noise.

The system and CPU temperatures were read out in parallel using two different tools, GPU-Z and the MSI Control Center. The fan speeds were read out via the MSI Control Center.
The system was equipped with the Arctic BioniX P120 as front fan and the Arctic BioniX P140 as rear fan.
The following scenarios were tested:
- open case, idle, fan on auto
- open case, idle, case fan at maximum speed (volume measurement only)
- open case, fan on auto, stress test CPU & graphic card with Prime95 and the Unigine Superposition
- closed case, idle, fan on auto
- closed case, idle, case fan at 50% speed (only volume measurement)
- closed case, idle, case fan at maximum speed (only volume measurement)
- closed case, fan off, stress test CPU & graphics card with Prime95 and the Unigine Superposition
- closed case, fan on auto, stress test CPU & graphics card with Prime95 and the Unigine Superposition

There are no big surprises with the measurement data. The Arctic BioniX P are quiet and smooth, even at maximum speed and with the housing open, the system is still in the “whispering” / “quiet wind noise” range at 25 dB. A vibration noise was not perceptible at all.
In order to cool the test system even under full load with Prime95 and Benchmark with the case closed in such a way that temperatures similar to those of the open case are reached, the fans do not even have to be set to full speed. This goal is already reached with 1600 rpm or 1800 rpm (70% PWM) and it remains pleasantly quiet with just 22 dB. Without the fans, the test system heats up by 10°C during the 30-minute stress test and the CPU temperature rises to more than 90°C. The test system is also very quiet with just 22dB.
