I bought a pair of blowers for the Cobalt and they are so darn noisy. Has anyone bought a brand they like that's fairly quiet? I know a flange mount would be quiet but I'm not spending $400 for 2 blowers.

I want to hear them a little but I don't want to have to turn the stereo up when they're on.

Thanks

I mounted mine on pieces of 1” rubber hose, instead of screwed directly to the fiberglass. Cut down on noise a LOT as the rubber acted as a dampener. Screw a section of hose to fiberglass, bolt blower to hose.
 
A big box store will have vibration isolator pads for air compressors for a few bucks a piece. For example Home Depot online carries powermate brand. They’re made for the purpose flyboy suggested. Also good for under generators.
 
Sadly they are loud just marginally quieter vs non isolated brand . ITs the design. Cheap Small wheel spinning very fast vs large squirrel cage wheel spinning slower but moving more air . The squirrel cage fan is much more expensive.

I installed Jabsco continuous duty rated squirrel cage blowers which are quiet; so quiet I sometimes to forget to turn them off. Money well spent.... The only real issue is the circuit breakers needed to step up from 5 amp to 10 amp. My real purpose for them is engine room cooling.
These will probably be the last blowers you will need so from that perspective - cost effective.

What was the specific Jabsco model number? How hard was it to swap out the breaker? The latter part seems like it would be kind of complex on my '07 310 DA, at least replacing the existing OEM breaker.

They are P/N 35770 flex mount http://www.xylemflowcontrol.com/files/357X0_43000-0673.pdf
The breaker change was the easiest part. You probably have the A-Series protected off in your main circuit breaker panel like these https://www.bluesea.com/products/74...Flat_Rocker_Circuit_Breaker_-_Single_Pole_10A
Inside of the circuit breaker panel one of the terminals is screwed to a copper buss bar and the other to the wire to the blower. Your wiring should be 14gauge so plenty large enough for 10 amps.

Thanks. I didn't know they were Blue Sea (and/or compatible with Blue Sea) breakers. For some reason knowing the breakers are fairly easily replaceable makes this seem easier, even though I suspect actually getting at the blowers themselves might be a PITA, actually replacing the blower itself doesn't sound hard.

I am going to look at this, I would like quieter blowers. I don't know if I can afford to make the generator quieter (mine lacks the sound shielf), but making the blowers quieter would make the general racket less obnoxious. There's times I think the blower noise is half the problem.

if access to the current blowers is difficult you could just reposition the new blowers in a more accessible spot in the ER and run power and ducting to the new blowers.....

I guess my thinking was that replacing the blowers is one of those tasks that has its own obvious complications in terms of access or needing to replace ducting or something, but ultimately hinges not on that, but on replacing a circuit breaker.

If the breaker wasn't easily replaced it seems to become kind of a bridge too far unless you wanted to go down a more complex path of running new wiring and a new switch to control the blowers or some other rube goldberg system like re-using the existing blower circuit to control a solenoid which actually powers the blower.
 
I replaced my old probably original blowers with the Atwood's and the were much quieter. You can still hear them, but they are not annoying like the originals.

This is what I wanted to hear. I got the Attwoods last night and I am getting ready to install them now. I don't mind hearing them I just don't want them to sound like a cat going through a lawn mower.
