Washer Size

[Vulcanrvn90]

Hi,

Im currently trying to find the right size washers and grommets for mounting my 120mm fans to my case and my 360mm radiator to my case. I want to install grommets for everything if possible but if not then definitely use washers. I feel like however that most that i find have a hole much to large for a typical fan screw, so what is a good size of washer to get? Isolate It! and McMaster-Carr have some really really cool products but I have no idea what size the inner diameter I would need or what size outer diameter I would need, ideally the washers would be just slightly bigger then the screw holes themselves as to not stand out.

 

Anyone have any idea of these numbers?

 

I have rubber fan screws for the case fans but obviously I cant use those to mount the radiator to the case, what would y'all suggest to act as a dampener between the radiator and the case? I have a radiator gasket for one side of the mount but on the outside (where the screw head is) I have nothing.

 

Here are some of the cool parts they have, does anyone think that these push in bumpers could be adapted to work as radiator screws?
