hi,

how does having multiple fans affect the db rating. ie is having 4 20db fans going to be louder than having 3 20db or is it just the highest decible rating that will be roughly the ammount of noise your pc makes?

thanks

Doubling the number of fans adds 3db. Every 10db if noise increase doubles the volume. So going from 1 to 10 fans doubles the noise.
