Question: What does the word “whine” mean in this context?

Answer:

“Whine” here is being used in its literal, non-figurative sense — a high-pitched, continuous sound, similar to the noise a small child makes when complaining (“whining”), or a mosquito’s buzz, or a small motor running at high RPM. In audio/electronics terminology, “coil whine” specifically describes:

Pitch: high frequency, often 1 kHz–10 kHz range (whistling/singing quality), as opposed to a “hum” or “buzz” which implies lower frequency (50-500 Hz, more of a vibration-you-can-feel quality)
Character: steady/tonal, sometimes with a warbling or pulsing quality that tracks CPU/GPU load changes

Your original description was 滋滋 (zī zī) — in English this maps more to “buzzing” or “crackling” rather than “whine.” Zī zī suggests a lower, more textured/electrical-sounding noise (like static or a faint sizzle), whereas “whine” suggests a cleaner, higher singing tone (like a jet engine spooling down, or a dog whimpering).

This distinction actually matters diagnostically:

Term	Sound quality	Typical cause
Whine	Clean, high-pitched, tonal	Inductor coil vibrating at its switching frequency — classic “coil whine”
Buzz / crackle (滋滋)	Lower, textured, electrical-sounding	Could be coil whine too, but also: loose component vibrating against something, a failing capacitor, or even a fan bearing issue as your friend suggested
Hum	Low, steady, droning	Usually mains-frequency (50/60 Hz) related — transformer hum, ground loop
Click/tick	Discrete, repeating	Relay switching (some PSUs click when protection circuits engage), or mechanical fan contact

Since forum posts (which I cited) use “whine,” “buzz,” and “crackle” almost interchangeably when people describe electronic noise in English, I’ve been treating your 滋滋 as covering the same general phenomenon — but if you want to nail down the exact mechanism, it’s worth describing more precisely whether it’s a clean tone or a grainy/textured sound, since that would help distinguish “definitely an inductor” from “possibly something else mechanical or electrical that just happens to also come from near the VRM.”
