As the title would indicate, I'd like to know the exact hole spacings (and also diameter) of the mounting holes for a 140 mm fan/rad. I'm looking into making a small-ish AIO that needs a 75x75mm to 140x10mm adapter. But given the width and height of the fan itself is 140x100 the mounting holes would be smaller and I need the dimensions to create an accurate bracket with.

Thanks in advanced

mount for 140mm fans are 125mm, for 120mm fans, they're 105mm. Holes are 7.5mm from the edge of the fan if it has a full frame. As far as hole diameter, I think they're between 4mm and 4.5mm usually.
