Actually, now that you mention it, it could be 92mm. I only roughly measured and don't believe 95mm is a standard fan size. 92mm with 2500 RPM sounds like it should fit. But then again, you'll be looking at sinking even more money into an already expensive and not really ROI'ing device.
I don't know the place you are holding this Apollo device in your house, some different room or basement, and maybe you don't have problem with noise that is creating.For my devices I am always trying to reduce noise by doing some modification, but I am silence freak and I don't recommend this to anyone else.
If you are ok with setup you have now, don't cut or change anything
But you can surely tinker with this, if that's your thing. As I said though, there's only so much you can do when facing 200-300W and trying to cool it with a single fan. Just consider gaming PCs (at least a few years ago) pulled barely more than that; often shipping with 500W PSUs, and using chunky tower coolers and multiple fans in the system.Coreboot is a great addition to a trust-minimized node setup. It's questionable if that's needed for someone installing nodeJS 9 and a proprietary miner binary, though..
My point was that I can use those laptops for multiple use cases, for anything related with Bitcoin.I am much more limited with Rpi devices.
