A few questions how does sound work? If i get a 18dba fan say and i get 2 does that mean it will be 36dba?
I mean this is in my bed room how quiet will it be?
Still need help :'(
Ah physics--that I can help with.
dB is a logarithmic scale, so things do not add linearly. It's designed to reflect the way the ear responds to sound, where twice the sound power sounds much less than twice as loud, and 1dB is about the smallest change in volume a person can easily detect.
To cut to the chase, if two fans put out twice as much sound power, they would measure only 3dB higher. Something that *sounds* twice as loud *measures* about 10dB higher, and requires about 10 times as much sound power.
In practical terms, multiple slow-turning fans will sound quieter than one revved-up fan moving the same amount of air. And, all else equal, a big fan will sound quieter than a small fan moving the same amount of air.
So the best strategy for silence is to buy as many big, quiet, low flow fans as you need to move a given amount of air. I have multiple Nexus 12cm fans doing this--each one is almost inaudible, and additional ones don't increase perceived noise much, if at all.
So for silence, go for:
- Big, slow turning fans, as many as you need.
- Smart airflow (radiator shrouds, balanced intake/exhaust, correct paths).
- A quiet pump, well isolated from its mounting surface--hung by elastic is ideal. (High flow is not as important as many think, and increases noise, pressure, and likelihood of leaks.)
- As big a radiator as your budget, space, and aesthetics will allow--radiators are a silent way to increase your cooling capacity.
The loudest noises in my system are the very quiet pump, and the occasional seek from the hard disk. Definitely quiet enough for a bedroom.
Hope this helps.
