stupid question about evercool fan

I just bought a couple of evercool aluminum 120 mm fans. The screws they supplied (4 of them) are kinda short. I intend to mount it to or screw it to a homemade shroud...but the fan is too thick and the screw is too short...

is thtis the intention? how do you mount or screw this ting?

I would go get threaded rods from you local hardware store, and flying nuts.

Use robber grommets when tightening the nuts to limit vibrations from the fan against the shroud.

What he said...
6-32 bolts or rod with #6 nuts and washers should do you swimmingly.

thanks, now I have a number to go by while at Homedepot...number 6!!!

What the heck are those screws that they supplied do? too short to fit anywhere
