Fan Noise
For easier comparison of PSU fan noise results we have separated our test results into three groups with a chart each:
- Up to 500W: Typical PSU ideal for a single video card system.
- 500W to 750W: Plenty of power available for most single and dual video card machines.
- Over 750W: For the most hardcore, power hungry and overclocked setups.
With such a high efficiency (= less heat inside the PSU) I can't understand why the fan of the NRP-MC851 is running so fast and loud. It would have been easy to start the fan extremely slow and ramp it up as power draw increases.
