Pretty self explanatory. I have a 120mm fan mount which does not have a fan filter. I need a fan filter for it.
So is there a link or shop to buy fan filters? I am located at kolkata.

If not then how to make a homemade one?

The best you can do is find a mesh, get a piece of sponge and slice a VERY thin layer of it, find a way to stick it in the mesh (fold the edges of it) and mount it on your cabinet via screws..
very DIYiy, might look ugly even, but this is exactly what is done in my cabinet (the air filters)..

Sponge? Won't it be too thick a filter? I need some good airflow. As in I need come air on the back and top of the motherboard area to keep the socket cool. And the 80mm fan at the back pushes a low amount of air anyway. Just want to know whether a sponge will restrict airflow too much or not.

Hmm I'll try out the sponge.

[MENTION=127841]nikku[/MENTION] where can I get AC air filters?

Will musquito nets or a pair of old socks work? :p :D

Hahaha, I just spotted an old unused net at the corner of my room :p Will try and use that.

Btw anyone knows where I can find 80mm fans that are 15 mm in width? All the ones on flipkart are 25 mm wide.
