I ordered a NH-D15 G2 HBC twice now from Amazon. The first time I immediately saw bent fins on the top of the front tower (
first unit fin damage). So I returned it immediately and ordered a second unit hoping that I just got unlucky. Second unit arrived today and I again have bent fins at the top of the stack of the front facing tower (
second unit interior corner fin damage,
second unit exterior corner fin damage).
I never got to the point of installing these coolers and testing if it has a rattling issue, but it seems consistent with the possible cause that Noctua identified.
I have a brand-new NH-U12A on hand that I'll use for my build instead.
P.S. Customer service is trying to blame Amazon for trying to sell a used product as new. Despite mentioning "Rattlegate" (and that Noctua has publically acknowledged the issue) they seemed unaware of the issue. I didn't really expect CSR to help me...I was just hoping they would pass it along to manufacturing to help track down this issue. Well, I tried at least...
