I posted numerous post on how to get the fan noise down and looks like no one even read it. Now you guys are trying ridiculous mods to bring down fan speed instead of using common sense!
I asked you a question regarding your "shroud" mod a few pages back, but didn't receive an answer. I'm trying again. You achieved a decent noise level reduction by installing the shroud, which judging from your photo also removed the finger guard. Given that removing the finger guard alone reduces the noise level, did you check how much reduction resulted from each of the two changes (shroud with guard, shroud w/o guard)? That would be helpful to know! Thanks!
EDIT: I just realized you responded to my earlier question with a PM. Sorry I missed it, please ignore this post!
