Review on SilverStone Technology SST-FF81 SST-FF81B 80mm Fine Fan Filter with Magnet Cooling - Black by Ronny Goodman

Does the job; The screen corresponds to the description. I chose it because people liked the manufacturer. It has a magnetic frame that allows it to stick to the PC case on top of the rear fan, but no wonder it's a weak magnet and can fall off if touched, so I added two small fridge magnets and it works fine. I can add a stronger fridge magnet. The filter screen doesn't seem to slow down the airflow appreciably. Note that it covers the intake fan. Maybe it'll be blown away by a strong fan blowing outwards, but I still think it's a good idea to add fridge magnets. I considered many possible solutions before settling on this one. Beware of positive reviews from people who don't pay attention to whether or not a particular solution is blocking airflow, because things that block airflow *act* to cause the internal temperature to rise, but it's not noticeable unless , you watch the temperature - - except the components can fail much sooner due to overheating, and in some cases they can throttle themselves to avoid overheating, reducing performance. I deducted a star for such a weak magnetic frame.
