Hi again, Doc.
No, I'd say it isn't. I learned in the military that brushes in high speed
fans can fail after only a few days. That's why computer and equipment
cooling fans don't use them. And these guys have a two year warranty.
Some modern fans can generate EMI if the the motor driver or tach-output
oscillate at RF. Soetimes leads provide a UHF "tank circuit" that helps
