Tent height and heat using same wattage

Nice one on the replacement fan dude!!
Thats Great customer service when they go beyond what's written in the terms and conditions

Yeah, thats fricking awesome. I need to research more on terpenes loss regarding to temperature cause info over the internet is very different. The 80 (26,6 C) thats what i heard From the stash podcast, but people also use co2 and higher temperatures so it cant be very huge loss

Thank you very much, i have some exciting news (for me but also future customers) that ac infinity sent me an replacement without any charges although im out of US ! And i can keep my current unit. Their site clearly states that their non charge policy is applicanle only for US. As for measuring heat thank you for your explanation, that can describe why my white cable thermometer showed lower readings. I will read more about leaf vs air temperature, for now i thought that they just cool down them self and always have lower temperature and thats it. Love exploring science with you guys !

Yay! Glad to hear they sent you another one. Now go make some dank stank!

I will . I tested today how new fan sounds connected to silencer and carbon filter and voila this high pitch is not present like in the faulty one. They even included controller 69 instead of 67 with replacament. If i turn off heating in room etc i can reach 65-66 degree ambient temperature so ill experiment some. If ill have temperature/sound problems still ill just grow with half of my tent, doing some mini sog or something like that. Hate this apartment cause i can hear neighbor talking, sometimes even understand full sentences, shitty old building :/

After some time of playing around with this fan. The new one whines at level 3 instead of 4, so it must be motor problem. Ac infinity sucks all the way, i will have to attach another silencer/acu ducting beetwen fan and filter or just save for other fan. I cant believe how poor this product is for its hype. Another apple - like company but shitty made. F**** ac inf.

I never understood the blind loyalty to ACI. People will defend them as the best in the game. The amount of paid advertisement the company does should be a red flag to everyone. Every podcast, website..etc

theyre just another vivosun-Esque style company with a better marketing department.

Exactly. I have to say that i came across same whining noise related issues across internet regard infinity so that speaks for itself. Whats the point for me to run it on level 2,4 but avoid 3 like hell lol, the old "faulty" one whines across 4-5...
People reviewing it throw "32 db" numbers comparing it to 50 db of other fans, but other fans at least mentiones distance etc of measurement. AC infinity not and call it "total noise", lol if it'll have 32 db on max i would grow 1000w led in apartment, but that amount of noise is not possible for fckin 402cfm fan.

Never had any issues with mine

It appears always after connecting carbon filter, maybe my filter is resonating, maybe it adds too much resistance. Maybe other people are not worried about this sound like i am and dont notice it. Im just tired this endless battle . Its funny that i didnt had this problem when running 5-6 in 2x4 and now it creates problem with my 2x2 on lower setting. I heard that it whines a little when switching levels so i guess changing pressure drop in system can help. I hope just that my neighbours wont notice it through ceiling. I cant hear it through nearest wall. I have prima klima's filters pressure drop chart and bigger filters create less resistance in summary (less stepped curve). Im literally laughing at myself for how much i overthink it and how long this thread has become. Has anyone used two silencers in a line and notice big difference in airflow beetwen 1 vs 2 of them ?
A lot of amazon reviews and videos mention/shows that motor is not silent (8 inch and 6 inch). Quality fan + quality controller would cost me more, i should stick to my head wise words of mine friend "if something is for everything, its useless".

I do think it's probably some sort of resonate frequency been created by the filter or the connection.
It's not something I've ever noticed and the tones that used to bother me was fan hum which passed through brick walls easy.
I've always used a reasonable length of duct between fan and filter and fan and exit.

Aslong as its a constant humming you will have no problems turn it on when you have loud music and everyone will get used to it by the end of the day.

Thats what im hoping for (people assume another home equipment), im paranoid because of thin walls but hey people use air purifiers, white noise machines etc that are more noisy. It sounds like humming but not like buzzing but constant frequency of about 250-500hz. It would be pretty sad to give up again cause i already germinated seeds. In future im going to support silencer outside tent to make room for more ducting beetwen filter-fan. But this type of frequency is hard to block. Another silencer, building support for outside all of this gonna cost less than new quality fan but im afraid all other soundproofing is gonna be failure. Hate to say that i boxed my fan in mdf with 4cm dense foam and result is poor. I worked 3 days 24/day on a movie set to afford this infinity. Funny how much work i putted with this. Im hunting for coreywebster’s fan (boxed one). I watched some td silent videos but those fckrs make very noticeable high hum. I dont know any other good quality fans. Local shop sells some mdf boxed centrifugal but it will be another gamble for a lot of money. Lot of people mention panasonic whisper and i found Panasonic FV-30NFL1 WhisperLine Remote Mount In-Line Spot on amazon it seems its similiar to Coreys HCSF (although not, it have AC motor and probably isnt centrifugal)

I was hoping its that but previous one (which i still have) hummed with different filter. Silencer lowers this hum on outlet side. Now im pretty sure its motor. First one hummed on levels 4-6, newer one on level 3. It can be heard when its ramping up levels. As you said earlier it can be bad balanced blades or just motor that is poorly assembled and resonates at certain speed (frequency). Fortunately its not as loud humming as first one so im gonna take a risk now. I literally watched most of videos showing cloudline working and in every of them you can hear one frequency breaking through airflow noise. Not what i expected from EC motor fan, and that was one of main reasons i choose it. Maybe they work better with US electricity as my is 230v/50Hz and US is 110V/60Hz

I'd say its an issue with some other variable other than the fan, Not saying that its not possible to have two faulty parts but its highly unlikely

Whoever knows man... i once talked to a sound engineer who had very precise hearing. He told me a story that one neighbour was drilling few days and he left his drill connected all the time. Sound guy heard some low frequency at night and it was annoying for him and couldnt find the cause. Turned out connected drill made some radio interference that was traveling through building wires/structure. So everything possible. My noisy upstair neighbours gonna have to live with my new "air purifier" frequency in tent lighting hours lol.
Amazon review video check this vid, for me its not just air movement sound.

Well stick some egg cartons on the top wall if you are paranoid about sound soo much.do some sound proffing of the walls

Egg cartons dont block or absorp sound. I checked and its around 400hz hum, not bad as people voice is 85-255 hz (yes, my place lets me hear a little muffled conversations). I was thinking of soundproofing but my building is just shitty build and if i soundproof for example a ceiling, sound will flank by walls - waste of money. Paranoia is one thing, but shitty fan is a bigger one.

Yeah a lot of those other box fans are made to shift huge amounts of air and aren't that quiet.
Gecko and hurricane types.
I even bought one from black orchid and that was loud. I must of loaned that out cuz I can't remember seeing it for ages.

I bought that bundle of 6" fans I told you about second hand.

Costs 1000s to soundproof .
Would literally need to have a room within a room fully isolated.
It's a lot of work.

Then buy a big fan and run it slow or one of those bladeless fans

How do they perform in contrast to HCSF ?
