Some of the new Barker cases, I'm doing them all at once.
The whole case has to be pulled, you've got to pull the plenum out just to get at the fans.
Yep, a couple of cheap 9watts make good sense in that case

There is a proper position for a fan blade within the plenum, and installing a larger (or smaller) sized motor can and WILL change that postition, altering airflow for the worst!
Replace the motor with the proper sized one.

Going higher in wattage will use a thicker motor and place the blade above the plenum. Going lower in wattage will use a thinner motor and place the blade below the plenum.

Yes JP and it would be a very bad idea for me to disagree with another fellow
CM that has all those rounds on his profile page
By all means always take my 45 years of information with a grain of salt as I
don't mean to criticize others and there are how many grains in those rounds?
I am so thankful for this forum as it often shows many of us that some of the

Always go by mfg specs first then if that doesn't work go right to the source
and ask the mfg application engineer
They will help you as they are proud of their product and their reputation

I'm new to markets but in my short experience I would have to agree that this case probably needs to stripped down and cleaned, and possibly even tape off some of the lower louvers to forc
