@lanodan In terms of size noctua already makes proper packaging for their iPPC line. And I'm quite certain they could've fit the accessories underneath the fan if they wanted, as under the cardboard sides holding the fan in place there's mostly empty space. Maybe make the packaging a few mm thicker if needed.

I have no issues with the accessories they include, that's great. The problem is that they package things so the inside of the box is mostly air.
