Was transferring about 80g of files wondering why taking so long, seems the integrated WIFI module was cooking itself, running at 105 - 108 C (rated 20 - 80 degrees).
Guess it's a hiccup in the mobo that it doesn't ask the fan to speed up to compensate unlike when the CPU or main chipset gets hotter. Anyhoo apart from not being healthy for the module (luckily it didn't die even though I left it like that for a hour) the noticeable effect is throughput throttling / stuttering.
FYI: Most other references I found were in laptops - they too often overheat the WIFI module if there's not good enough/clogged airflow, and apart from burning your legs the usual result is, "damn the WIFI really sucks here."
Disabled the integrated WIFI, plugged in a T4UH (from previous machine without built-in WIFI) - so instead of the chintzy antenna hanging out the back on a 1m cable there's the T4UH (it's on a 1m cable plugged into a USB3 port) ... bonus: T4UH actually get's a better signal too - 4 bars compared to 3 and noticeably better speed (diagonally through a reinforced concrete wall).
As promised for the Rasberians
did find reference to the same happening in the Raspberry Pi ... enclosure too small / bad airflow, doing a lot of WIFI work (i.e used as [busy] AP) will often lead to it's WIFI module overheating and thus reduced throughput.

How many files is 80g? Because in electrons that's around 8.782153e+28 ...

This made me think about my laptop fan bays and started me thinking about cleaning the dust out of them.

I have the wifi disabled on my pi's, but it's because i don't need wifi on them.

This one ... well, yes, ok - some of it is a good idea, maybe. Learning frets and such, yeah: https://popuband.com/[^]
But it's still a ukulele chaps. That's never going to be a good idea, unless you want to be a George Formby impersonator.

Perhaps I should upgrade my ancient guitar so that it spares my neighbors from having to call the police because they think I'm torturing cats again. That reminds me that I have not yet tried to learn to play a guitar this decade.
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

Good grief. Get a strat for cryin' out loud.

A piano key weights much more than a keyboard key. An important aspect of learning how to play involves doing finger exercises to strengthen one's fingers. Practicing those exercises in a keyboard won't be as efficient, and will have an impact in the agility of your son's fingers. That doesn't mean he can't be virtuoso with a keyboard, but it'll be harder. So I would advise against it.
However, I also live in an apartment, so I understand the dilemma. A good compromise (and what I did) is to buy a small electric piano that fits nicely in your living room. Plus, you can wear headphones, should the neighbors complain. The sound won't be as neat as with a normal piano, though. Just make sure that the weight of the keys are close enough to those of a normal piano.
Should you decide for the keyboard, make sure that it has at least seven octaves. The common keyboards have five octaves, making it impossible to play most of the common classical pieces. I did learn in one of those, and it was very frustrating. Seven octaves will cover almost every easy and medium level pieces, and a great deal of the advanced ones.

THANK YOU thousand times! You explained it very very good! Now, because of the circumstances he most probably needs to decides for a Keyboard... and I have to give away my old piano 
Seven octaves: yep, that was my "biggest" worry, but I googled sevreal and found also several with with 88 keys. So for this we are one the safe side.
Thank you very much again.

Do you have a Suggestion for a specific brand/model (yahama, roland, ...)? Thank you again.

The one I have is considered to be a digital piano with semi-weighted keys and I think it feels very close to a real piano. I don't think it's even made any more but I like it. It is an Ensoniq Avista. I would recommend a digital piano for learning in an apartment environment.

Thank you very much for your Response. "Ensoniq Avista" is very new for me. Because of the background that I'm a Drummer I was searching for Roland. Need to check "Ensoniq Avista."
Thank you, Bruno

I mostly agree with Fernando's reply, but just wanted to add a few things.
A digital piano (keyboard) is definitely the way to go, but I'd strongly encourage a full 88 key model with weighted keys. It will never need tuning, and has other advantages over an old piano such as MIDI ports which can be used to drive a virtual keyboard/synthesizer on a computer, or to work with learning software...lot's of possibilities. I bought a really nice Yamaha as described for about $450 a few years ago, the prices will be lowest through the holiday season. Good luck!

Ahahhh, so you're cheating your bass with a Keyboard
"With weighted keys": What this means exactely?
Thanks, Bruno

They feel and play pretty much exactly like real piano keys.

Now, that I'm playing myself piano, until now I never experienced a Keyboard which responds nearly the same as a conventional piano

A friend of mine has one with a full 88 weighted, velocity sensitive keys. Sadly, I can't remember the name on it, but it cost about $3,000, 20 years ago.

Ok, I will Google for this "weightedm velocity sensitive" keys. Thank you.

At the Moment I think I will go for a "Yamaha YDP-S52WH" (about $1000). Not easy portable, but that is also no Need. Next Weekend I will go to test it. Let's see

Weighted keys feel much like playing a real piano with all the moving parts...like they have some weight to them and not just cheap plastic. I forgot to mention that the keys should also be velocity sensitive...most of the decent ones are.
Yes I'm cheating on my bass! Thanks for remembering! Lately I've been playing bass lines on an acoustic guitar...put on Pandora Classic Rock and just play along.
