I have an EVGA P2 750 that's been serving me well for about a year. It's developed some coil whine but that's been behaving fairly well for now. However, the PSU fan itself has been making a noise that sounds like air being forced through a tight passage. It's not a whine, not a buzz, not grinding or anything like that. I almost thought it was coil whine again but realized the sound vanishes when I turn off the fan via econ mode. I can hear the fan motor slowly power down and the whistling fades out when the motor stops. Turning it back on, the whistling returns immediately regardless of the motor.
I recorded the sound as best I could (it was difficult) --

I found one other example of someone else with the same exact issue --

(In this one you can hear the fan being switched off and the noise fading, then coming back immediately when switched back on)
The sound is audible if my room is dead silent, from about 2-3 feet away from my PC. It's entirely possible the sound has been there for weeks as I constantly have fans inside and outside my room going, basically overpowering any noise from my PC. I only heard it when one day I turned on my PC before turning on my fans lol.
EVGA wasn't very descriptive, simply saying "fan problem" and offering a RMA which I'll take eventually. Can't afford to have no access to my PC for 1-2 weeks, don't have spares and don't have money for a cross-shipment RMA. I will in maybe a week or two so I'm gonna cross RMA it then.
For the time being, I'm just wondering what the cause of this sound could be. It's not dust or obstruction, I cleaned the hell out of the PSU and had no change. Switched to a different outlet and the sound persisted. Almost sounds like it's 2 separate sounds, because I can clearly hear the dull hum of the fan motor if my ear is pressed against the PSU. It doesn't change depending on load/temp, it's basically the same pitch with no interruptions power on to power off. It also doesn't sound like fan bearing grinding to me, like I mentioned I almost mistook it for coil whine. Tilting the tower left or right has no change, nor putting pressure on the fan grate. I've noticed it a few days ago and haven't heard/seen any change in volume or behavior.
