Re: How noisy are the cooling fans?
IT "basics" also includes a knowledge of electronics and radio. Most of my colleagues had no idea of how a computer and its associated electronics worked. Therefore they could not double-guess when underlying constraints in the technology might be responsible for intermittent errors in the system.
Even something as simple as the speed of propagation of electromagnetic waves through various media was a mystery to them.
I even had an official "network designer" once ask me about speeds - "What does 'mega' mean?".
