I've thought about an external fan but haven't got serious about it. I still need to open it up and check for the noise.
I am no expert on it (since I don't own a PowerPro) and this is just what I read online, but the idea with this kind of solution is it keeps the PowerPro cooler. I think I saw 10 degrees cooler posted somewhere. Supposedly, the clean air getting pumped in from this HEPA filter causes a positive air displacement inside the PowerPro headstock, i.e. always air going from inside to outside through any cracks and openings. By creating a positive air displacement, in theory, no dust would ever enter the PowerPro headstock, so it cuts down on the stator position sensor errors that creep up from dust infiltration into the headstock.
