Silverstone Technology SST-FF123B-3PK 120mm Ultra Fine Fan Filter with Magnet Cooling

Some of these reviews had me hesitant but I had to remove the front cover of my new overheating PC and needed something amazon fast. This brand has a solid reputation and arrived in branded packaging that looks legitimate. The magnetic frame works great and the only reason I can see it falling off is if the wrong side is used. Unfortunately, my tower has screws in the way so I have to screw them on. One downside to that is the top filter bulged out a bit when tightening it on so make sure you don't overtighten the screws and it should be fine. Idk if the 3pk I bought is of the highest quality they make but the price was decent and the filters do a great job without obstructing much airflow. My temps stay below what's recommended to safely idle and run games without having to add fans. You can't buy any random filter. Most use PVC and other materials that obstruct too much air. I wouldn't settle for anything other than nylon and this brand has lived up to its reputation.

Please people, buy filters. Keep them clean. Your PC will thank you. These are great filters - fine enough to filter small dust without being overly restrictive. Many filters are so large they'll filter pet hair but hardly any dust. These are the perfect size, easy to clean, and have sufficient magnets to hold them in place.

The filters that LianLi includes with a lot of their cases (I have the 011 Dynamic and Lancool II) are very restrictive for air flow. For a while I just took them off and dealt with the dust, but no more! I bought a HTPC case from Silverstone and was very impressed by the included dust filters and I wanted the same solution for my 011 Dynamic. These dust filters are magnetic and super easy to install on the 011. They work amazingly well and the fans keep the same volume level with the filters on and off which is not true with the included LianLi filters.

Very fine filter, the filter is high quality. The magnet is pretty weak, though, and when I put 3 in a row for the top of my case, they are slightly too big (I screwed them in, but there was a small bulge on each filter's magnet surround). But I cannot find anything else with a filter this fine, and these keep the cat litter from my cats' fur from dropping into the case (they really like to lay on top of it lol).

Worked very well, mounted great, has a nice fine mesh, and the magnet could hold it to a pc case. Works very well and allows more airflow than the foam filter it replaced.

These dust filters are well made and can filter very fine particles. I used to buy cheap ones like these but the magnets usually separate and are somewhat flimsy. These are stiff and sticks well

Replaced the original filters in my Lian li O11 Air Mid Tower. I've had this for a week now so I can confidently review that after replacing, the fans are less noisy and have lower rpm. Temperature for cpu and gpu are consistently lower too while running games so airflow is much better. You can either screw it or just stick it on your case (if your case is steel) with the magnets.

The weak magnets made installation difficult. The filters kept falling off with the slightest bump to the chassis. This forced me to mount the filters with screws, which will make uninstalling/cleaning/reinstalling more difficult. The filters themselves seem sufficient to the task.

Wished the magnets were stronger. Doesn't impede airflow much. Dust collects on the filter pretty fast so make sure to clean the filter often. I've been using them on Tecware Forge M which has a mesh front but the case doesn't come with filters. 2 months in and there's just a tiny tiny tiny layer of very fine dust on the PSU shroud that was able to make its way through.

Die Löcher sind kleiner als bei Konkurrenzprodukten, daher klare Empfehlung. Lassen sich durch die magnetische Ladung quasi überall befestigen - verschrauben eben auch.

Me encanto, la malla es super fina por lo que complementa perfecto los filtros del gabinete que tiene orificios más grandes. Encaja perfecto en las fuentes grandes, además todo el marco es magnético y se agarra bastante bien. Lo he lavado y no se ha maltratado. En la bolsa se incluyen 3 piezas.

Quedaron a la medida son de 120mm los que yo compre la tela es fina por lo que se deve de tener cuidado a la hora de limpiarlos, eficiente para ese polvo finito que se acumula 100% funcional en la pc.

Magnets are weak.. mesh is great allowing airflow while catching small dust. Magnet function is non existant for my fractal north case
