ive just bought a 150mm systemair fan and its really noisey how can i make it quieter, cos noise may be a bit of a problem for me. i dont really have much space for a silencer but i may fit one in as a last option, and plus i heard that it reduces the amount of air the fan pulls through it........if any one has any ideas or solutions plz throw them my way........
Damper collars(rubber inserts), seperate metal contact of fan to duct
If nothing else put it on a dimmer switch
often a dimmer switch (setting your fan to a lower speed) will cause more vibration..
and more noise...
not always..

also if you're gonna be using a dimmer switch you have to get one that has the proper rating to suit your fan... You can't get a two bob switch designed for a house light cos it won't work (trust me).
humm interesting that I did not know
it works great for a smaller fart fan though.
but still noisy though, however not even half the noise of the bigger vortex fans :D
