Do Silencers work??

Title says it all really, so i have just purchased a 8 inch fan and filter to go in my 8x4 tent and fuck me its loud next door and underneath will think the planes are landing up hear..... what way do i quiet it down without spending £200+ on an acoustic fan......

Do these work

And the insulated ducting

People are going to tell you to wrap fan in sound damping. Careful with that, if sound canr get out then heat cant either. Can be dangerous.

I would try silencer and maybe some sound damping material on walls around it.

I’d also try the sound damping on the walls like a studio. If that doesn’t work a fan id recommend is one of ac infinity’s in-line fans they work like a charm and pretty quiet.

Doesn't the heat just blow out with the fan being a fan?

Oh this was totally not the conversation I thought it was.

Hang your ventilation and duct fan from rope hangers or something like that. Mounting stuff directly to the wall and ceiling will cause loud vibrations.

Oh you're in a tent, getting a fan speed controller and turning the speed down could help a lot. Just make sure its still giving proper air flow.

I second this. You really shouldn’t need an 8” running full bore for a 4x8 tent. Running it at 60-70% will greatly reduce noise.

Yes i think my fan mighg be faulty as he gave me a controller but it is noisier on lower setting untill really low il try uploads a video

Love the name, I am a huge Fallout fan. Well, the older games up to #4, the newer ones they didn't put any effort into. Fallout Tactics is my favorite but I haven't got to play it in a while.

It could have a broken blade, it will throw it off balance and cause a lot more noise.

If you have it set too low it will produce a loud humming sound. I have to keep my controller in the middle of medium or higher or else it produces a humming sound and struggles to get up to RPM when it cycles on.

Thanks man! Glad to see another gamer around these parts! Thought it was fitting to kind of reference towards cannabis colas too, I always spell it with a K though even though I know it’s incorrect lol.

Yes rhat what it seems like a huming sound when controller just over middle setting, nd like you say its quiet at nd quiet at low but thw sweet spkt humms qmd to loud on full the neighbours will hear..... should i get a silencer or insulated ductin or both.. i have send the grow shop guy a video off my fan

Is it a turbine fan or an aluminum duct fan?

Moving air will always cause sound and vibration, I don't think you will be able to fully silence it. It will all involve slowing air flow, so you might be better with a 6 inch fan.

This is what I bought for a 4x4 tent

How close are you neighbors? Do they have an issue with pot or you? Is pot illegal in your area?

Pot is illegal where im my neighbours bedroom on the next room qnd downstairs sittingroom is underneath the room tent is... il get a pic of my fan now

Here it is, its more or less to stop the dragon worrying a bit which stops the headache for me....

Yes they work (the ones with foam inside). They will reduce the noise signature around 50% in most cases depending on cfm.

Any right bends you have in your ducting will dramatically reduce air flow and probably contributes to the sound.

Your best bet for stealth would be a smaller fan, a 6 inch. Your tent is going to hum either way though.

Yes 1 right angle, will it be better straight with a silencer....

I have found that when using lengths of galvanized snap seam on the blower (both ends of it) that it gets really quiet. The slinky duct not so much.
