I sympathise, many PC's these days are unbearably noisy. I got one that was
unacceptably noisy and simply took it back to OTA the next day and asked for
a quieter fan. They obliged. That's the easiest and simplest solution.
Incidentally, a larger fan is quieter for the same volume of air because the
fan blades can rotate more slowly.
If a quiet fan isn't an option, there are ways to quiet the device.
Basically, you have to put it in a sturdy enclosure with a labyrinth (a duct
with bends in it) for the cooling air to pass through. The labyrinth is
lined with absorbing material that absorbs the sound.
You may have noticed a generator wagon on film shoots. The thing is
generating thousands of watts of electricity from a diesel generator, there
is a plum of exaust gas coming out the top, and it can hardly be heard at
all. So it is absolutely possible to quiet a PC.
If you like, I can provide more details, I used to do consulting in
acoustics and noise reduction.
