Some Wire Mesh/Filter/Fan Grill Testing...

I know this is an old thread, but I'm looking for 120mm and 140mm-sized fan grills, and I'm trying to find the least (air flow) restrictive grills I can. From these tests, it looks like the hex-mesh provides the best air flow (least air flow restrictive), but I was hoping a circle wire grill would have been included in the tests, to see how restrictive it is.

To the OP - would it be possible to test a circle wire grill, to see how it compares to the hex-mesh for air flow reduction (which is more air flow restrictive)?

jbsteeves, are you referring to this style of grill:

The restriction to airflow with that style of grill is going to be negligible - I seriously doubt there'd be any impact on cooling. They're not going to keep anything out of the case except fingers, pets and tumbleweeds, tho! :D

Hi ScottAllyn
The very nice post about the dust filter materials for PCs. But today is 2016, on the market there are many other filters: DEMCiflex fan filter, DustEND fan filter, etc. Can you make new testing with the new fan filters and materials?
