120mm Fan Dust Filter Mesh 4.72inch Magnetic Frame PVC PC Computer Case Fan Dust Mesh Cover Grills Black 5-Pack

Work Well, easy to clean. Airflow is somewhat restricted but acceptable.

There is not much too these but compared to others I have seen the finish is nice with the edges being clean cut around the magnet shape, to the point you could have them exposed and it not look sloppy. They do what they claim, magnetically attach on the case and act as a filter before the fan. While this is not going to keep all the dust out it will help capture some of it before the fan blows it all over inside of your computer.

Looking through the comments I've seen some reviews mentioning that they don't seem to stick well, but honestly they seem to hold themselves on perfectly fine, at least for me. They actually look really nice too, the edges are rounded off really well, they have no creases or damage whatsoever, and overall construction feels great.They do a great job catching dust, I'll give them that. However they restrict airflow a ton, the holes are TINY. This isn't an issue for the PC i used them on, because i really just wanted to cover the unused fan grates so the CPU cooler would stop pulling unfiltered air through the sides and top. But if you require high airflow for your PC, these are going to cut it down a good bit. Blowing through them feels like a good 50% reduction in flow.

These fit my intake fans perfectly. Do not put them on output fans, the reduce airflow and you are only trying to keep dust from being drawn into the case.

I used this item on the rear fan since I swapped it from exhaust to intake. Definitely has lowered dust ingress. Magnets make them super easy to remove.

No matter how clean you think your house is, it's amazing how dust is drawn like a magnet to cooling fans. Having these screens prevents that dust from entering my entertainmnet center. They're easy to remove and clean to keep that equipment 'breathing' healthily.

To start off, this is a very well made product, the quality is really good and the dimensions are on point. Having said that, buyers please be aware that the holes are the size of pinholes. For decent ventilation, with this material (not foam), you want the holes the size of ballpoint pen tips. Make sure what you're getting into before you get dust filter with holes in this size. It may work for some people who don't really game and only watch movies and web browse with their computer. If you're a power user who stresses the CPU and GPU, you want fan dust filter that will allow more air through to prevent raising temperature and throttling.

I only needed one of the because for some odd reason the corsair 750D doesn't include a mid bottom filter. But that really doesn't matter. They work, though. can't complain.People complain that these restrict airflow...Yeah they do! anything you put in front of your fan is restricting airflow. Use high pressure fans. Mind blown
