Hello, when the 0db mode is activated in the power supply, the fan starts up during intense gaming sessions, but before it activates, a peculiar buzzing sound occurs, similar to what was shown in the video (video not mine). I understand this is normal, but is it really? The noise bothers me, so I need to disable the 0dB mode to eliminate it. I used Google Translate, sorry for any errors.

The faint whistle sound could be from the fan bearing, especially at low speeds. Fans typically run within a certain RPM range, generally between 600 and 2000 RPM. It's uncommon to find a fan that works efficiently at just 0-500 RPM unless it's specifically built for that. A whistling noise from the bearing usually appears when operating below 600 RPM, which is quite typical. Not every fan makes this noise at low speeds; it's a normal occurrence. You might want to avoid using 0dB(A) mode or consider upgrading your PSU if you want quieter operation. For example, Seasonic PRIME models have 0dB(A) mode without any fan noise, and I've personally experienced this with two of them.

Yes, it's the noise when the fan begins at 0:08 in the video, like a buzzing sound. It's normal, so no need to worry. Thank you for your answer
