How many fans are in the Axe 3? What size are they? How big are the heatsinks? Any pics?
It's in the previous posts.

Well but at that time, people wanted to swap a 60x60 fan for an 80x80 fan, changing the cross-sectional area.Volumetric airflow isn't the only thing that matters when you're cooling a CPU...or even the most important thing.
It shouldn't. But it sounded almost like an echo, as if there were a delay attached somewhere. It'd be an interesting experiment.
Agreed. But the proposal was to enlarge a hole, which would decrease the velocity.Well but at that time, people wanted to swap a 60x60 fan for an 80x80 fan, changing the cross-sectional area.

Understood. And I think you're right in that the discontinuity could add noise. But there would still be a reduction on air velocity (the area of the hole appears to be about 85% of the fan aperture), though I don't know the design numbers, so I don't know how much margin you'd be giving up if the hole were enlarged to match the aperture.Hi Rex,
If you're referring to my post, I was suggesting the hole in the aluminum was smaller than the outlet hole of the fan. I'd suggest though that the hole in the _center_ of the fan would be very close if not identical to the hole in the aluminum (Don't have my iii yet so just going on that photo a kind user posted). So - in effect, the hole in the aluminum is the same size (or real close) which means the overall velocity would be identical - Just that the air has to flow over an uneven path.
Thanks

Interestingly, the bulk of the noise in the video doesn't sound like wind noise. There's something else going on.

Lo and behold, I reassembled things and the low-pitched drone was gone. At least in my case, it seems like @kartman was spot on talking about uneven or excessive torque on the fan frame.
