Hey guys/girls.
As some of you are aware (And if you're not, you've learnt something.) If you buy a cheap fan speed controller (Varii speed controller ect ect..) You'll find once you turn the speed of the fan down, it will make a humming sound (Not all fans do this as far as I am aware). And this could be a serious breach of being stealth, and even if noise isn't so much of a problem, it's just nice to not have the fan humming in your ear while you're working with your plants.
So in this real quick tutorial, I'll explain how to build a silenced fan box
Please note: I take no responsibility if this doesn't work (I've not made it yet ) and I take no responsibility for what you decide to use it for either.
Tools needed:
1x Toy box (Can be bought in various stores in the UK such as B&M, QD, ect ect)
1x sheet of kingspan/celotex ect ect..
1x pen
1x cutting tool for plastic.
1x glue spray/liquid.
Step one:
Take your fan, and circle round your fan where the ducting conects, and then cut out the hole do this on both sides.
Step two:
Take your insulation and cut it into sections so that it fits inside your box perfectly. Also cut sections out for your ducting.
Step 3:
Glue/tape your insulation to the insides of your box including the lid.
Step 4: put the fan into the box and then push both pieces of ducting out of the holes. And put the lid back on. (do not attach to the carbon filter just yet.)
Step 5: Plug fan in, and keep lowering/heightening the speed to check for noise.
Step 6: Once you've checked the noise levels of the fan, then connect it back into your Carbon filter.
Step 7: If you're having your fan inside of your room/tent then attach it with rope or something simular.
Step 8: Everything should now be pretty much silent (If not silent a hell of alot quieter).
Step 9: Post here with your results
