I've already contacted the computer's manufacturer and they did not
know.

There are 4 empty screw holes where a bigger fan would fit into. The
distance between and including these screw holes is about 87.5mm. I
know the computer cannot handle a 120mm fan as I mistakenly bought a
fan that size and it is too big to fit into those empty screw holes.

I feel like Goldilocks. I need a fan that fits just right. How do you
determine the size of the biggest fan the computer can handle if I
know the distance between and including the the screws?

You can always retrofit the 120mm fan either by drilling new holes or
make a bracket. The trick is to mount the fan securely so it does not
vibrate. The fan should have at least 70% of the airway unobstructed.
