Questions about MikroTik Cloud Router Switch CRS310-8G+2S+IN

Does anyone have any experience with the volume of the fan? - If anyone has even unscrewed the thing, does the fan use a standard PWM interface, so that a Noctua might also fit in an emergency?

Is this one compatible with the Fiber7 10 Gbit/s setup from Init7? I think the fact that there are 2 SPF+ ports should suffice, but just wanted to make sure if there is anything I'm overlooking?
