The most common problem of this sort is that when the RAM upgrade is done, the little fan control cable is not reconnected properly. Without that cable, the fan is set to default to run all the time at full speed.
I would return the unit to the dealer who did the upgrade and ask them to check and reconnect the cable if it is disconnected. It should take barely 5 minutes.
I would question the proposition that it is a prevalent issue, simply because we have no quantifiable evidence to show what proportion of systems suffer from it, either subsequent to service or even without being opened. We see a number of reports of it here, for sure, but that's not a reliable guide as to how commonly it happens in general.
It might be that the cable would better be colored more brightly such that it is less easy to overlook it, but I suspect it's purely carelessness - particularly when service was undertaken by an Apple approved service provider, who should certainly know better.
Problem solved in 15 minutes.
I don't have a putty knife so I tried opening Mac mini's case using this trick + two very thin knifes:
and after a close look, I've found a small cable near the power light disconnected. I just plugged it in gently and voila, no more fan running all the time.
Thanks for your tip, you were right!
I also called the Apple guy and he apologized a million times and told that yes, he forgot to plug it in again.
You're welcome, thanks again for your tip.
To help other Mac users with the same problem as me, here is a picture of the opened case
The small cable I am talking about is located in the front, exactly between the first and second white plastic pins/hooks/locks, counting from the right to the left.
