Mesh filters Help

[Samuel Hammond]

Hi not sure this is the section to post.

My pc case is: Lian Li O11 Dynamic XL (ROG Certified) Aluminium Full-Tower - Black and I am looking for 120mm Fan Mesh Filters Magnetic but bigger holes than the mesh filters it comes with for more improved airflow but still managing to collect dust. I can't seem to find the size of the holes.

Kind regards.

If you want to replace the long ones, (side panel, bottom and top), can be tricky to find substitute. If you want to add individually to each fan, a much easier task, as can be fitted sandwiched between the case and the fan. Just watch out for filters that may sag and catch the fan or filters that, being too close to the fan, will add some undesirable noise.
What locations are you looking to use the improved filters? Also, what’s your fan layout? Intake and exhaust and location?

3x Noctua 120mm NF-A12x25 PWM Chromax Pressure Fan with Swappable Anti-Vibration Pads Bottom and 3x Noctua 120mm NF-A12x25 PWM Chromax Pressure Fan with Swappable Anti-Vibration Pads they're intakes and exhaust fan one on the rear and 3x on top. I would like it for the intake fans for better airflow I think the Lian Li mesh are really small.

You’re correct. I found the O11 XL quite restrictive, maybe because the panels are quite restrictive too.
If running without filters isn’t an option for you, I would try some individual metal ones first. More like a mesh than a filter, if that makes sense.

Demciflex are quite popular, but never used them.

Demcflex are good filters, they catch a fair bit of dust while maintaining good air flow.
