I used to have this noise, but i solved it now, it is the fan causing vibration to the case, and somehow this vibration met the resonance of the case. so it is actually the case was vibrating and releasing that noise. What i suggest you to do is to loosen the screw of the case and re tighten it. This is how i fixed it. btw this noise shouldn't cause any problem while flying.
Hey Alex, brilliantly simple solution. It may not work in all cases, but easy to try nevertheless.
Check out this break-down (of the P4 - the P4P appears similar in other photos) and note that one corner of the fan isn't secured and may rattle against the shell with the P4P as I understand it's a different fan (a miniscule piece of foam pushed under that corner would resolve if it is):

I suspect that loosening the closest screw and re-tightening may allow the shell to settle better. Otherwise, for warranty reasons, I'd suggest only this and not pulling the P4P apart as per the break-down above. It's at your risk if you do, of course.
Otherwise, the fan in my P4P doesn't vibrate against the inner shell but it is quite loud. I didn't realise how loud it was until I pulled my P4 back out. OMG! It's almost silent in comparison! |
