[@oby-1607]

Good tips there. So many people just put up with the noise when it can be better. The bigger fan with reduced speed was the best.

[@heididecker707]

You are incredibly informative and you packed a lot of real set-up information into a short video! Thank you.

[@nunyabeezwax2059]

For ducting insulation I recommend sweat pants. They come in pairs for both the intake and exhaust sides.

[@Silver1080P]

Darn, this is a really good idea. Does it work nearly as well as all purpose insulation though? That stuff can be pretty cheap, only downside is slightly more assembly

[@josebrown5076]

Bro.....you are the man right now to the third power......i literally thinking damn my inline fan is way louder then i wish it was and the cardboard box is major since i already had it connected directly to the filter ... thanks bro

[@ThisTall]

I have that exact fan built inside a wooden box, with 6 feet of flexible aluminum ducting running from the intake to a window. And the intake is actually quite loud, but it is still loud overall.

[@pasgas12safe58]

Thanks mate, simple but effective demonstration with the cardboard box & to build a wooden box, wth 2 holes to snugly fit around the ducting going into & out of the box will retain more noise from the fan.👍

[@richardstuivenberg4618]

I have primaklima 350cfm inside my 5x5 led grow tent. I put it on mode 1 of 2. Carbon filter on one side and insulated ducting on the other. I can sleep next to it. Because of LED Lighting you dont have to run powerful fans anymore. As long as you have a negative air pressure inside the tent your good. Keeps the smell inside and plenty circulation. I do like that box idea. Especially with some eggfoam. Maybe ill take the fan out of the tent and test it out.

[@worstHorse12397]

Loooove the insulated cardboard box idea. My budget is happy. Thank you.

[@kaceydamas6517]

Dude, you rock - thank you! I am building a lampworking studio and this will significantly decrease noise.

[@truescotsman4103]

i use a 20x20x1 air conditioner return filter and the grill for mounting it installed on a plywood box with the fan inside. it filters the air and keeps the fan much quieter. I have the inside of the box carpeted. filtering the dust and mold spores out of your circulated air increases the commercial quality of your stuff exponentially as an added bonus.

[@muhammadusman2045]

Come on dude whats the point of playing Music will testing (plus Music with bass)

[@ATH3IST-FLuKE]

Fantastic tips, but I do wonder if this isn't producing an accurate noise without the ducting hooked up to the Carbon filter?

[@joel1544]

you can hear the hum the speedster causes on the lowest setting. A variac is a better option it changes the voltage input instead. Worth the money and have removed that hum from 3 different brands of fans with them. hope this helps.

[@tinderella2386]

Yeah without getting into proper VFD/VSD drives like they use in industry, the SMSCom hybrid pro controller seems to be the Only hobbyist level fan speed controller id trust, and is a 5step transformer it clunks between and is actually a solid and very heavy piece of kit. No humming and I highly recommend them

[@ceili]

Complex yep, this

[@Silver1080P]

Better demos of the sound differences would be nice. Maybe a couple different kinds of ducting or box solutions

[@davidlopez-trujillo2419]

Do you think the speedster will work on a squirral cage homemade 2 speed fan ? Or nah

[@StAnger561to770]

Awesome video guy. Was debating insulated duct. What do you think about running extended duct inside the edges of tent on the floor sealed at the end with vertical slits throughout. In essense an air diffuser to better bring air throughout tent instead of just at the end of the shorter duct. Another consideration is with extended duct the intake fan weakens. So you need a stronger intake fan for the same effect as before. Finally what about reducing the intake/exhaust fans speed at lights out? Especially if the fans are bringing colder winter air in at these times.

[@StAnger561to770]

Got another idea how about a coffee can insided a cardboard boxes. With something around the fan and boxes like a carpet. Or that polyfill stuff.

[@1999straker]

REMEMBER all fans require a certain level of ventilation for them not to overheat as a retired electrical engineer i would not put a fan in a box because it could overheat and set for to your grow room buy a better fan

[@richardwallinger1683]

oops big metal blender must NOT introduce fingers .. Great video ..

[@HelloKittyFanMan]

And what's this inline fan used for that our air handler supposedly already can't... uh... _handle?_

[@jyj3843]

I have a situation where I only need to run about a foot , should I use the insulated ducting or use the muffler (duct silencer)? What say you fellas? Which is pound for pound more effective. I'm running it from the fan right to the filter

[@sheftWEB]

Hi...using Wood box dont over heat the motor?

[@dastanharris]

my thought exactly..

[@cbas1974]

Hi, great video! I'm looking for the best quiet fans with the most CFM for little windows 12 inch it's for my martial arts school facility . It' 80'x16'x24' we have a lot of windows directly toward the sun, so in the sumer it's huge hot inside! I want to change the air bettween, 10-15 minutes, so I need 2 or more fan but witch one I don't know... Before I saw your video I looking for: 2x S-1000 Vortex 1081 cfm or 2x AC infinity Cloudline T8 or Vivosun Inline 8 inch. But with you trick for noise maybe an another choice will be better... thanks

[@rickrappaport5920]

Oh, the Duct Silencers, assume they need to be of a certain length to work? Not much room to put an inflexible piece attached to the air purifying unit but how do I accurately measure the diameter and just how much room the silencers will take up? Assume I'd need them on the intake and outflow ports of the air purifier?

[@2GUNMASTER]

Adding a filter will reduce sounds but it I assume it also reduces cfm, correct?

[@nicewhenearnedrudemostlyel489]

i think hundreds if not thousands of amazon shoppers would get much better results or at least have more realistic views if they actually applied what they watched here.

[@rickrappaport5920]

Thank you for the great video. Just cut holes into my furnace (professional did it not me) and attached an extremely noisy air purifier via flexible ductwork to it. The purifier attaches to the cold air return and then again to the forced air into house part of the furnace so this 3' x 20" x16" air purifier has two 10" flexible ducts attached to it and it makes so much noise we are not using it! "Housing" it doesn't sound like a good idea since it has these big ducts attached to it and I'd have to work around the big ductwork (there are no louvers or air slots in the air purifier so it can otherwise be covered up in some way. What's the best approach? The speedster sounds promising but I don't want to defeat the purpose of exchanging the house air by reducing the fan power too much (and maybe what I'd need to do for noise reduction would defeat the intended air purifying purpose). Can't really put it in a cardboard box without cutting holes in the box for the ducts. Suggestions? Thanks!!!

[@shahrestoon]

Hi dear Monster Grower I accidentally(stupidly) put my hand in the Aluminium outlet of my fan to insert an ONA BLOCK inside but it blocked the airflow for a small time 2-3 seconds max and it made the fan sound louder for that period of time . Now I think that the fan has got Louder while operating . is this the result of a quick outlet blockage or that blockage won't affect the fan function at all ?I would like to know if its only in my head or the fan can get damaged/louder if the outlet is blocked for couple seconds ? Thank You for considering my question

[@goonernumone8444]

Dont know about using chains to hang one to a joist, a bungie cord is much better as stopping vibrations ive found !

[@WarriorBuddhist]

[@notsosure7757]

Fan should be mounted on either teaco pad or some anti vibes. There's nothing wrong with using stud as long as there's an anti vibration system in place (usually in the fans installation instructions) . Then a flexible canvas either side of the fan, connected to an attenuator/silencer. That's the only way a fan should be installed if you're worried about noise.

[@shadowplay2002]

If its in a growtent and i use ducting will you hear it outside the growtent? If yes, whats the best thing to do, a silencer or build a woodenbox around the complete tent?

[@MonsterGardensChannel]

Either or Copper -- Hyper and Can Fan offer their silenced fans, the STEALTH and Q-Max. Cheers!

[@shamanbeartwo3819]

I have a grow tent and no fan in the tent is nearly as loud as the fan in the living room all summer or the fan above the stove or the bathroom fan. And I don't have a model built for quiet or anything else done to help. The oscillating fan is louder than the inline duct fan. And in my last apartment, I ran an 8" inline fan and no one heard it. A fan turned on that is not connected to anything sounds loud. As soon as you connect it to any kind of ducting or lights, it gets quieter since you are damping the motor sound on one side. And if you put the fan in the middle with ducting on either side, it gets pretty quiet.

[@prof.dr.gambohechel4030]

Doesn't a fan heat up in a box, so it could start burning...even with that paper-material/cartonage....?

[@MRBROWSER2012]

Those neoprene clamps didn't work for me with an 8" ipower and filter (it leaked). Ducting on both sides of the fan is a must for that style of fan.

[@MRBROWSER2012]

I started with a 4" fan/filter combo kit and the filter mated fine with the fan because the fan port was tapered. Used duct tape to seal it and it worked fine but not enough CFM's for my 5X5X7.8 GG tent. So I bought the 8" fan and filter kit from Ipower. Different style ports didn't fit together well even though the vendor shows that configuration on Amazon. I had to use a few inches of ducting between the fan and filter with some 8" band clamps. Have everything hangining inside the tent with rachet cords. Vibration from the fan is completely isolated now. I was thinking about adding one of those inline sound dammpers as it's just blowing into the attic and worried my neighbor might hear the fan since my attic is level with their 2nd floor. For now I have the fan at about 1/4 speed so its probably not noticable at that speed but may want to up that speed as it gets hotter in my area.

[@MonsterGardensChannel]

How is the iPower working for you? Minus the compatibility, are you satisfied?

[@MRBROWSER2012]

Works really well. The instructions are lacking. More than enough flow for a 5X5. Bought the high CFM pole kit from GG to keep the tent walls from sucking inward too much.

how much CFM did it lose when the silencer was installed?

[@AffinityPhoto]

I don’t get why they used cheap “sound reduction” garbage foam that has extremely low absorption values (but it looks *cool* behind vloggers on their walls). Better off with Caruso isobond polyester which has absorption values around 1.0 for 150-5000Hz. For 6” ducting, get a foot of 8” pvc with two 6->8” adapters. Get the 1” (30mm?) isobond (or make it from magic eraser pads) and glue it to the inside wall of the 8” pipe. Assemble the ends and plug it into your blower. For sound coming out of the fan assembly itself, get a roll of dynamat and use the adhesive side to wrap around the blower excluding the controller which produces heat.

[@davewozere2k9]

How about a larger fan than you need, running at a slower rpm :p

[@MarcAntoine01]

That's actually one of the tip if you watched the video

[@Nine-Signs]

You can also make a slightly oversized wooden/fibreboard box, line it in mass loaded vinyl then closed cell foam then towel, then pop your fan inside it with snug holes cut for its in/out and pop the lid on. Should reduce the noise markedly.

[@suminshizzles6951]

USE a variac to control the fan speed instead of promoting trash products that will not only be louder but also dangerous. Those cheaper fan controllers most of the time use light switch dimmers "repurposed" as fan controllers and sold at markup accordingly. They will make your fan HUM really loud. And that will be noticable. This clip is advetisement for this guys. TRASHY ADVICE

[@joeblogs8589]

You completely missed the point of insulated ducting. Also, what is the point of slowing down a powerful fan to reduce noise? May as well buy a cheaper, low-volume one then.

[@I_am_not_a_bot-s6i]

Bigger fan on 1/2 power will move a lot more air than a small fan on full power and a lot quieter, air moving fast makes a lot of noise. I use a 8" hyperfan with insulated ducting in side a 1.2x1.2 tent with 10" carbon filter, you can stand next to the tent and cant hear anything. I run a 600w hps and it keeps the temps at 28c perfect. If I was to use a 6" on full even with everything else i would not beable to sleep next to it, also a bigger fan on slow setting with over sized carbon filter, you get longer carbon life iv had my filter over 2 years and the only thing you can smell are my feet lol. Trust me the cost is well worth it, smell free and silence i would not grow with out it you have to put your ear to the end of the duct to make sure it's on its that quiet. The Best, most cfm, and quietest fan on the market by far hands down. rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F322308062474
