Noctual NH-U14s Rattle

[WozT]

I installed the U14S last night and thought everything was OK. Today I started threading cables etc and noticed any touch on the case produced a high pitch rattle / twinkle. Even a light thump on the other end of the table induces it.
Any tap on the U14S produces it. All the subframe and mounting screws are tight.

Help and advise appreciated.

I had one myself and it did this too. Only while the case was laying down on its side. Is this the same as with your problem? If so, it's quite normal.

I'm using a Aerocool DS case, the motherboard sits horizontally, in this postion it rattles.
So I turned it on it's side and it went, turned it back upright and it's there again.
I bought this cooler as i thought i'd have no hassles, gutted it's twinkling away, nice to see I'n not alone though.
