In fact, this filter material is indistinguishable from the filter that was included with the Lian Li 011 Dynamic EVO. I run an unconventional air flow setup in this case with the top and bottom radiators as exhaust and the side and rear as intake. So, I needed to filter the rear 120 and two vent sections on the side panel where air is drawn into the case. I was looking at much more expensive custom made filters, but read a lot of reviews about the rise in temps due to further restricted air flow. I am happy to report this DIY filter media cuts down on dust intake and does not negatively effect my temps. Cutting the material was super easy with a box knife and the magnetic strip's adhesive sticks well. Overall, awesome kit. Review: The magnets are pretty strong - Got a case that came without filters, and these worked great as a replacement. The filter is easy to cut, the magnets aren't hard to cut and apply, and they stick really well to the case. They also look good. Also haven't had any airflow problems. The temps stayed the same with and without the filters. ## Features - 【Superior Dust Protection】: Keep your PC components clean and extend hardware life. The ultra-fine PVC mesh effectively blocks 90% of dust while maintaining optimal airflow for cooling. - 【Hassle-Free Magnetic Mount】: No screws or tools required.
