Review on 🖥️ HFEIX 140MM PC Fan Dust Filter 5.51x5.51 Inches (LXW) - 10 Pack, Black (140x140) by Casey Vance

I have a server/workstation combo with 7 fans. 2 are exhaust fans, and sometimes (usually after opening the case to clean everything, reinstall circuit boards, etc.) the power cable (or the controller cable going to the liquid cooling system) gets caught in one of them, and as long as there isn't any damage , the noise is very annoying. And of course I also have to open up the case again and route the cable etc. Placing one of these on top of two exhaust fans makes it easy to fix this problem for good. I already installed them many years ago, on another 6 computers here, and they worked fine there - I ordered them when I finally found them on Revain (too lazy to do a proper search to find them sooner , I guess - or maybe it was out of sight or out of audibility = out of mind). They work particularly well with the bottom intake fan located next to the PS where a fan is more likely to have an intermittent wire snagging issue on the fan blades (off etc) than the top outlet. They work well as dust filters on all bottom fans by the way and I would say they are very useful. By the way, they work well for both 120mm and 14mm fans. Although IIRC I had to drill one of the sets of holes (120 I think - but it's been a few weeks and it might have been 140's. Sorry), an operation that took a few seconds at most. Definitely helpful and highly recommended.
