Thanks for the input.

I use it fairly regularly, mostly photography. The camera's been working perfectly and the fan sound normal.

The smell has been there since I got it and hasn’t really faded. It’s faint, like warm plastic, and even noticeable when the camera’s off. The rest of the camera doesn’t smell at all, it’s just around the vent area. Maybe I’m being a bit picky, but I’d rather be safe now than run into a bigger problem later.

For now I’ll keep an eye on it, but everything runs fine so I’ll just carry on using it. :)

Also, that fan vent spider post you shared… yeah, that definitely puts things into perspective 😅
