Need Help Quieting a 10" Can Max Fan... Should I use a Rhetostat or?? Please Help!

Hello all and thanks for helping! I purchased a 10" Can Max Fan to push air through my air cooled lights, yet it is VERY loud. I even added TWO of the Phresh Duct Silencers, one before the fan and one after the fan to try and kill the noise... I must say that the silencers do work but each one only killed about 10-15% of the noise, but its still too much. I have it running full speed at 1014 CFM and I am thinking that with the use of a rhetostat I could slow it down another 20% and it should be very quiet and still have super high CFMs... I do hear noise coming from the intake on the Phresh 10" x 32" filter as well, which I would also like to quiet... I also read on here about making a DIY box around the fan body and filling it with memory foam or dynamat to kill the motor resonance. Do you have any links to a good DIY fan box that would work for the 10" Can Max Fan? I read that I cannot use a cheap speed control like the speedster or titan speed controls, because they do not work like a rhetostat and I thought I read on here that you can ONLY use a rhetostat on the CAN MAX line of fans... Please provide me with a link to a rhetostat that will work with the 10" Can Max Fan, and links to a DIY fan housing muffler box, if that is the correct route to take... Please help me get this fan setup quieter as I need the high CFMs this fan puts out, I just can't have the noise... THANK YOU ALL IN ADVANCE!!

Is your ducting insulated? If not might wanna consider that route if the noise is to loud from fan. When I didnt have insulating ducting to my exhaust it was quite loud.

Sorry forgot to say, yes all ducting is insulated...

Yeah dude get a controller for your fan and turn it down some. That will quiet it down for sure.

I wish it were that easy... I read online that the speedster fan controllers and titan fan controllers will NOT work with a Can Max Fan.... Only something called a rhetostat will work, and I am not sure if it has to be the Can brand or not... Anyone with knowledge please advise as to which specific Rhetostat I can use... Thanks again all for your help, this issue is really stressing me out!

Is there anybody out there with a 10" Can Max Fan dialed down 20% on a speed controller that is not buzzing or overheating due to the speed control? I heard the speedster type will slow it down but also make the motor buzz more. I know the Can brand speed control that doesnt cause buzzing and is a rhetostat but its $300...

The high dollar controller is simply a "variac"... Google/eBay amd check these forums with that keyword....

fill out the contact form on their site, see if they ship to the states. Looks good not much info on them though

There are tons of variacs listed on eBay...

Get a router speed control from harbor freight. How is the fan mounted too? Hanging from bungee cords is the best way to isolate vibration.

Can somebody please delete this post, for some reason there are no delete options available!
