Fans mounting holes

[SlaveInabox]

Are you aware that the mounting holes on the 40 x 40 fans measure 3.5mm?

Do I have to drill them to 4mm?

I was not aware of that. The last shipment batch had a different brand fans because the usual supplier couldn't deliver. I assumed the dimensions of the holes would be the same, because the outer dimensions and specs are, but this appears not to be the case. Drilling them out to 4mm should not be a problem as long as the blades and cables stay intact.

Sorry for the inconvience,

Guillaume.
