It doesn't take a boffin to know that if you turn a fan very slow, it
won't make much noise. Trouble is, it won't move much air, either.
Isn't the issue whether it moves _enough_?
It might be that the Noctua fans have a blade design that moves an adequate
amount of air with unusually low noise.
Absolutely correct.
Two or three small, quiet fans, will probably do a better job than one
large, "noisy" fan.
Nearly right. A bigger fan is better because it can spin slowly and
therefore be much quieter than the equivalent small fan. This is why
if you become interested in PC silencing as I am, you will quickly
find out that it is better to have a slow spinning 120mm fan than a
faster, noisier 80mm fan.
I do know that I wish
the fans on my computer were quieter. They're not noisy in an absolute
sense, but I'd rather they made no noise at all.
If it bothers you enough you will research the issue and replace the
loud fans on your computer with quieter ones. And if you spend long
enough and try out enough fans, you will eventually realise that
Noctua make the best silent fans available.
If you are using the stock cooler that came with your computers CPU, I
guarantee your computer can be much, much quieter. Likewise if you are
using a power supply (PSU) with an 80mm fan; your computer is making
more noise than it needs to be. PSUs with 120mm fans are always, in my
wide experience, quieter.
On most computers the PSU and the CPU cooler are the 2 biggest sources
of noise.
