Obsessive-compulsive attention to detail led to all sorts of weird spiders for Newtonian secondary mirrors.
Perhaps we can start a small revolution in cooling fan motor support and protective grilling?
Noise is one of the major issues with cooling fans in all fields of use.
Air turbulence could easily be part of the unwanted noise issue and could cause flutter vibration in imaging applications.

Hi Chris,

I checked my images and the stars are still round and do not have a feline eye shape yet ...
About the shape of the spider ... perhaps elongated drop shape like the wings of an airplane but that would be for this ridiculous fan application too much ...
Look at the price of NOCTUA fans from Austria and simple fans from WINSINN from China ... NOCTUA adds some special supports for vibration reduction and that ¿ is the reason for being 5x more expensive ? ...
regards Rainer
