Try to clean the blower section of the fan. Dyson fans are notorious for getting clogged with dust at the bottom section and the turbine blades. This may be causing the motor to work extra hard resulting in the noise

I have posted an article on how to do this at the following link:

The OP didn't specify the model, but if it has a filter like the TP01 then there should be no dirt getting inside the fan, only on the exterior and in the filter (which obviously if it is dirty will cause the fan to heave a bit as it tries to move air), but at least for the tower fans (TP01 specifically in my case) there are 2 other distinct noises caused by other issues outlined below.

From the link, I can see the AM07 has an updated design and foam on the retaining ring to stop the plastic squeaking I mentioned in the post below.

Out of the box, my Dyson TP01 had 2 sounds going on, a high-pitched plastic squeak and a metallic rattle like a bearing going out. Customer service were idiots and could only send me links to videos showing how to clean the exterior. This was after multiple attempts to get them to do ANYTHING.

I tore the fan down and found the plastic squeak. The motor sits in a ball (visible from the top) on foam (underneath only visible after completely disassembling) and there is a ring around the top of the motor cage with 4 flat spots that sit loosely on top of flanges from below. Adding some small strips of foam insulation tape between the motor and the ring stopped the plastic squeak.

I also ended up taking the whole thing down to the motor and while spinning with a drill, I added small amounts of synthetic grease to lubricate the motor bushings. This stopped the metallic rattle and the fan is super-quiet now.

Thanks so much.

Could you explain how you lubricated the motor? Ive gotten to the motor, but read that you shouldn't unscrew the single nut holding the fan in place and can't see where I would put grease.

[split into 2 posts because of the character limit]

To remove the fan blower assembly:

They use some pretty hefty threadlock, but you can move the nut enough to slowly remove it. Use a screwdriver in the slot on the opposite side of the armature (motor shaft) then with a wrench (I forgot what the size was) to remove the nut. The blower/blade assembly is pressed on and needs a puller. With the motor off the ground, I used a couple small pieces of wood to brace the back (motor side) of the blower and tapped the motor shaft with a punch until it was off.

To lubricate the motor bushings:

I wrapped the shaft in a paper towel and fastened a drill so I could spin the shaft (didn't need to fasten the motor housing to anything as it spun freely, but you can steady it with your hand). While tilting the motor so lubricant can drip down the shaft, I had the drill going pretty fast and added small amounts of synthetic grease (I used amsoil spray grease) while watching it get sucked into the motor bushings. As soon as the grease disappeared, I tipped the motor so excess would drip back down the shaft while it was spinning (to keep a bunch from going past the bushing and into the motor windings). I did this about 5 times on each end of the motor and never had any grease come back out, but I felt there was more than enough to last a while.

Reassembling everything was just as easy as pulling it apart and haven't had any high-pitched rattles at all in the month or so it's been running non-stop. The first time it got turned on my wife even noticed how quiet it was. :)

Thank you for this write up. Mine has been making a high pitch noise that is so annoying.
