MoKo 140mm Dust Filter for Computer Cooler Fan, [4 Pack] Magnetic Frame PC Fan Dust Mesh PC Cooler Filter Dustproof PVC Cover Computer Fan Grills - Black

My system is set up with 1 140mm fan at the front as intak, 120 at the back right past my cooler and a 140 at the top above the cooler both exhausting. My PSU is also exhaust. I had three spots for 140's that were empty and the negative pressure was pulling dust in the machine and I had to clean it often. Bought these and used them to cover the 3 openings that aren't being used since the exhaust was pulling in dust. The magnets are more than strong enough and the screen will keep dust out but the mesh is not so small that it will impede air flow being sucked into the case passively. The mesh is very flexible and the 140 size I purchased worked perfectly. Now I can just take the screens off and blow them out periodically instead of bringing my computer out on to the porch to blow it out.

The 120mm 0.5mm filters work great. Might be a little restrictive on airflow but I have a mesh case so it combines really well with my setup. It also looks good with the rounded corners. Magnets are stick fairly well too. The 1.0mm ones might be a little too big depending on your use case so make sure to check what's best for your case.

Easy to use, and they work great

First off, for how much this set costs, I have no room to be making any complaints. They work as advertised, the quality of the screen is great, they're a good product. That said... the magnets around the edge are poorly attached. Instead if being a square framed magnet, it's got separate straight line magnets attached to each individual side. Those magnets come off after a few dozen uses. But for the cost, you can easily replace them if/when they fail

I've been using these on my SAMA IM01 now for over 6 months at this point and I don't have too many complaints. I find the magnet strength to be satisfactory. It's not choking off the airflow for my PSU, they couldn't be easier to install, and they work with both of my metal cases. Overall I'd buy it again.

The magnets do not stick very well, and you have to arrange them in particular ways as the polarity doesn't match consistently. They definitely weren't strong enough to stick to the metal fan screws

Nice! I got it right with the first filters I ordered on Amazon after spending 15 minutes comparing them all... The perforations are perfect for keeping out dust/debris without constricting any appreciable amount of airflow. The filter holes actually match the size of the other filter holes that came with my computer case's fan grills. I bought these larger 120mm filters to cover an inconspicuous 80mm fan on the bottom of my case, thinking it to be less restrictive than a tight fitted 80mm filter. What also makes these perfect is they're easily removable for cleaning by using a magnetic border vs screw holes. The magnets are not strong enough to potentially affect my moving spindle backup hard drive towards the bottom of my case, but strong enough to keep these MoKo filters attached to the bottom of my steel case. These really are exactly what I was hoping to find...

I've had a problem with dust getting inside by Tower. I've used other products but the mesh was not fine enough. So I'm going to try these as they have the finest mesh. I proactively added a couple more powerful case fans to make up for any added resistance caused by the fine mesh.
