Thanks yeah I think I will keep this noisy fan for another grow is thier any ec or variac fans you recommend something quiet and not to pricey I am looking at the acinfinity cloud line fan ? Thanks for taking the time to help someone starting out
A variac is just a speed controller.
Any brands you would recommend?
www.growell.co.uk
At that price you can get a top of the line AC infinity blower with a smart controller and you won’t be disappointed
You might try a PC fan(s) if money is tight, pwm speed controls are as little as $3 on ebay. I'm running six of them, plus an AC Infinity. I really only needed the temp/humidity controller 67, but got that and a T4 for $90 on ebay.
Wow, that thing is loud, 60 dBA. Good thing it's variable speed.unfortunatly I'm in the EU rather than USA, the brands are a bit different, so I can't make a specific reccomendation.
I'm using one of these (6 inch version) and it's super powerfull and compact... it does get kinda loud at 100% ... but I don't even need to turn it up to 50%.
I could have easily got away with probably a 5 inch version but hey.

I have thread about duct silencer types here. „Egg crate” foam is used in studios to dissipate sound - change reflected direction to many angles instead of straight bounce of a wall. But this foam dont absorb or block sound. I bought one of those growshop-hyped silencer with foam and was dissapointed with sound lowering. Plus i believe the irregular shape of foam just reduces airflow much by air turbulence - same as when your flex ducts are not straight. The really good silencer i bought after was the one with glasswool insulation - glasswool can really absorb energy. It made things quieter. Both of them works by expanding duct diameter thus slowing down air movement, but foam dont do shit for absorbing sound energy. This is shitty marketing trick based on popular myth that egg crates soundproof band reherseal spaces - but all it do is improve acoustic inside room but neighbourd are gonna be still pissed off.
How many watts do you use in that tent if i may ask ? What are your temps in and outside when you run s6 on 30-40% ?
i've just set s6 today, until now was working with prima klima it had 2 options 220/440m3h, so the temps weren't going more than 28 on low circ, with 75% 200w viparspectra p2000, if you're asking power draw, no idea, don't mind it.
AC infinity dont even mention sound measurement surroundings and distance. 32db they list as "total" noise which i dont understand is it maximum or average from all levels. Any way i tested with phone app (not precise as professional with microphone) my 6" ac inf and i get results - lvl 3 - ~39db, lvl 4 - ~44db, lvl 5 ~48 db, lvl 6 - ~51db. Keep in mind i tested it with silencer on exhaust side and carbon filter on intake. In my opinion ac infinity is over hyped and they are mainly focused on having grow equipment completely controlled by one controller. Plus they use a lot of youtubers etc to advertise their stuff (if something needs much advertising it means its not as good to hold its popularity in a specific market on it own). The only reason i bought is because of EC motor adjusment is told to be most quiet instead of motor noises with normal speed controllers and buying expensive variac etc ones.Wow, that thing is loud, 60 dBA. Good thing it's variable speed.
AC Infinity is 32 dBA and most people run them at speeds 1-5.

T4 with 67 control. Low/high is set to 0-60% and it's been running at 10-20% recently.
