Does the noise level table reflect the faulty power supply or the fully functioning version which they sent you later?

The fan noise listed is for the original PSU with the defective fan. I did not do a full re-test on the second PSU. I mainly wanted to confirm the fan was operating the way it was supposed to and it did. The fan in the second unit started up at power on and was very quiet through mid power (29.8 dBA at 3' with a background of 27.4 dBA).
