I don’t think I mentioned this before, but back to earlier about hearing frequencies... I learned recently I can hear those things meant to deter young people from loitering/skateboarding/mischief through playing higher frequencies only they can hear in the area. Be glad you cannot hear them, they grusome.
That might also explaim why I can hear strange noises from my computer that isn’t from the speakers, and no one else complains about. If I sit in the wrong place with my laptop the high pitched noises drive me crazy. I think they might have to do with WiFi, not sure.

Those frequencies keep you away, what about the youngsters, the intended targets ?.
HD and fans could make HF sounds.
Are you sayin' that you are 'hearing' or sensing RF or RF modulations ?.
Dan.
Funny that hasn't stopped many kids from playing computer games (some almost 24/7 unfortunately).
I seem to recall reading of a fish and chip shop which had a problem with youths hanging around outside and making trouble. They dispersed them by playing Mozart though some external speakers. The shop was investigated for age discrimination and making a public nuisance.
Many moons ago, I worked in a classical records shop catering for the older and wealthier folks. Came closing time, we'd play "London Calling" by The Clash full blast, and that cleared the shop in record time.
The problem is, even if you stop playing Mozart, it will not stop the nuisance.
Because "The silence that follows Mozart is still Mozart."
So to speak, I'm an expert in clearing rooms. One hot summer day the DJ on my fave college station said OK everyone let's clear you a space on the beach.
😀 I had a friend that was a professor of art history that told all his students to remember that Mozart was still lighting farts when he wrote most of his music.
It’s coil and capacitor whine from the buck converters for the CPU. When the CPU load ramps up and down it changes C states and the transients make it sing. Almost every motherboard and laptop makes noise like this.
Does anyone here know why silicone rubber is a real no-no in nuclear submarines? And how does this affect many volume controls?
As to internal equipment environment, I am a fan of sealing the enclosure and using silica gel as both a moisture absorber and vibration damper. Also silver anti tarnish sheets are included.
Silicone rubber out gasses and causes the carbon brushes in the drive motors to fail extremely quickly.

Must be the specific formulation. Because saying silicone rubber in such a general way is the equivalent of saying "all steels are unusable outdoors uncoated" while completely ignoring the hundreds of stainless alloys.
If those sounds don't work on young kids they're masochists. It's not the HD or fans I hear, it could be a bad solder joint or something - it's very high pitched and reminds me of a 56k modem a little.
