Hi everyone,
So ive got a problem. 2 fans and $450 later Im still not happy with the fan I have.
So far I started out with a 6inch Silenced Hyperfan. I was not happy with the high pitch occilating whine sound like a jet engine.
So I threw it in the bin and got an 8inch Silenced Hyperfan, in hope to run it a lowest speed and not have any sound. Instead it also has a Whine noise, particulary at lower speeds.
I grow with a 315w CMH in a 4x2x6 wardrobe. I have acoustic ducting and a carbon filter, so the Air Movement sound is not an issue.
The other problem is that the 8inch Hyper fan with the silencer is about 22inchs long and 10inch round! I have had to construct a giant box that sits on top of the drobe, but its just ridiculous and overkill for such a small space.
I keep getting mixed reports on weather or not Mixed Flow fans make more or less noise than Centifugal fans. Also the fact that Hyperfan is chinese made, maybe be the issue.
I have heard this whine/whistle jet engine noise on every hyperfan I have come across, but thwen have been in other people grow rooms over the years and some of them have silent fans.. I have no idea what they were, but i know this does exist!
I have come across the Blaubergs at a good price... Either the Turbo G or Centro G... Can anyone tell me if these things are silent operators?
I really need something small, 6inch is maximum, would prefer 4 inch! but this will make a lot of noise compared to a 6inch i understand... What if I get a 4 or 5inch and sound insulate the shit out of it and run at ful speed?
Im really out of options and its pissed the hell out of me for the past 2 years! Need this problem solved..
Another thing is that I cannot see any fans in person. I am disabled and do not leave the house much, I am also pretty far away from major shops.
Thankyou for listening and helping
