Ok, i detached silencer, filter. Only fan in a box. Motor makes some noise still on 3. It can be heard as i switch it back and forth beetwen 2-4. Its just quieter than air sound that is now louder. It is amplified as soon as carbon filter is present. In my opinion on level 3 rpm its making...

Its venting into another room, through silencer. Frequency starts after a few seconds it settles on 3. Its noticeable at few angles. Saw mentioned that on amazon reviews. It must be bearings/blades/motor. The previous one was humming on other levels. It means they assemble it not precisely. Not...

Yeah so what is ?

How do they perform in contrast to HCSF ?

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...

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...

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...

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...

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 :P. Its funny that i didnt had this problem when running 5-6 in...

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...

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...

How do you guys put silencers or other part of equpiment outside ? My gorilla tent is 210 cm high so i would have to build some stand for silencer to be on that level lol

That is correct. I saw it mentioned like that on (and other places). Although my logic tells me its buds surface temperature thats most important for terpenes evaporations. Many of them still evaporates under 80f but after 80 this process is amplified and more of them start to do it...

In my opinion thats good as a baseline, not every fan produces same pressure with same cfm so some can lose as much as 50% some only 30%. Plus LED's convert more watt to light in contrast to hps if i understand it correctly. There is lot of good explanation on another forum in thread...

On what level you run your infinity in this 2x4 ? I just tested and my inf 6 on level 4 with box and silencer gave me 40db with phone measurement. Without box i had ~50db on level 5 (around 44 on 4 but i dont remember exactly). Every curve of duct will reduce cfm and the air battling those and...

I think thats another great option, you can wrap/cover fan even with some blanket to reduce noise from fan and motor sitting outside. Plus having only carbon filter inside you can place it in the middle of tent so you can intake passive from both ends of the tent.

I have 2x4 and im finishing setting up silencer with boxed ac infinity (for me they vibrate and make some motor noise) and filter. I just hang 2/3 of the silencer in the box, 1/3 is outside - i use 2 straps to support part thats inside. Thats how i v been able to fit everything in a straight...

Infinite times, cause water flow from my head to my fingers (endless flowing cycle)

Jesus i just ask to know what temps people have with their set ups and fans cfm… out of straight curiosity. Yeah indeed i am exhausting air from tent with air conditioner and i cool it with fan lol, i live in a different dimension where physics are flipped 180 degree

Hand is not good device cause ur feeling will change with humidity level (the drier the air more water from your skin cools you). But thanks :). Yep indeed i need to set up good circulating fans - i think i would set up those pointing upwards blowing above canopy level - to push hot air from...
