Completely strange question, but I can't find the answer anywhere...

I bought from a junkyard a Intel SC5250-E chassis to attempt to make a overclocked Haswell build.

It has a front fan slot near the "PCI guide area" that has in the horizontal direction 113mm of distance between holes, but in the vertical direction 96mm

What fan was supposed to go there? Or what device? I can't find anything that fits it!

I attempted that in the past, I asked around in a couple places actually, it was a full-on downvote fest :(
