seem to be working very well
by CharlieBought two of these for two intake fans on the side of my case that I think were letting a lot of dust in. Only a 4 because they do look quiet different from the picture, the mesh is actually white so they do really standout on the side of the case and tbh I think my case looked slightly better without them.Still they seem to work incredibly well as, I tried blowing through them before I installed them and the air hit my hand unimpeded. I assumed they probably would not stop much dust. But already a large amount of dust has built up on the bottom one ... looks like I will be cleaning them alot but at least it means they are working well.I think it is a 3 for aesthetics and a 5 for performance which averages out at 4 stars.Still all in all definately worth the money even more so if the intake fan is out sight.
