Need help determining fan size...

JustinSane07

So I have this case that has two case fan slots. On both case fan slots is two sets of screws. The interior ones I know are for 80mm fans, because, well, I had 80mm fans in there. The outside screw sets though, I have no friggen clue what size case fan they're supposed to be for.

I do know that from center of screw hole to center of screw hole diagonally on the 80mm screws it's like 98-99mm and on the exterior ones it's like 113-114mm. Going horizontal and vertical, the 80mm screw holes are 75mm apart and the unknown ones are 85mm apart.

Does anyone know what size fans the exterior set of screw holes are for?

I want to guess 92mm, but I'm not sure.

Your case documentation should say this. Do you not know what manufacturer and model your case is?

It doesn't. I dug out the manual for it.

And that's the case there. Nice little simple case.

I just got the idea to measure the 120mm on my current case. Those are like 148mm diagonally across, so I know it's not 120mm.

So I'm guessing they're either 92mm or 90mm....

A quick google search suggests that 92mm fans and 90mm fans are actually the same thing, and they're just named differently for whatever reason. Not sure if that's accurate or not, though.

EDIT: Thermaltake says 92/90mm is the same, and I'd trust them as they're a major fan and computer case manufacturer.
