Just got the S8. Hooked it up to my 8 x 24 Phresh filter. Turned it down to 50%. Turned it down to 25%.
Put the fan back in the box and wrapped it up. Sent an email for an RMA.
Sorry guys but the fan does NOT run @ 39 db as advertised. At full speed the S8 was at least 80db. Damn thing sounded like a jet liner and was louder than my central A/C. At 50% is was probably around 60db. I'm not exactly sure because I don't have a meter but I compared it to my Panasonic 340 cfm @ 1.7 sones...
