I'm getting a noise coming from mid/front/driver's side possibly. It sounds almost exactly like our car's air conditioning going full blast. Like a sound of air rushing past something. The noise really starts to be audible at around 3k+ RPM until I shift then I'll hear it disappear briefly until re-engaging the next gear.

I've been wearing a beanie while driving during the winter so I don't think I've ever heard this noise before. I keep hearing the noise coming from under/in front of or to my left while I'm driving. I checked if it had to do with wind rushing past my car but I can definitely hear it getting louder as I increase RPM.

If it increases with RPM it is possible that it may be belt driven. Taking the belt off is very easy and only takes 1 minute.

If the sound goes away when the belt is off, try using a screwdriver or something similar as a stethoscope on the different belt driven components (while the belt is on) to see if you can find the anomaly.

Also videos always help.
