/csg/, I took into consideration of your wisdom (and insults). I applied more epoxy to the fan blade. It works. The fan blade has held up. For now. I applied a glob to the opposite side of the fan to balance the weight. A bit janky but it works.
It's one of those handheld mini fans. Someone was junking it but I think I've managed to salvage it.
Though I still doubt this epoxy is strong enough to bond the physical strains of a laptop hinge as stated in the guide.
