Review on ThreeBulls 12 Pcs 120mm PVC Black PC Cooler Fan Dust Filter Dustproof Case Cover Computer Mesh - Keep Your Computer Dust-Free and Efficient by Marco Carpenter

I love her! They appear to be of good quality. You're not skinny and I'm glad I have all the extras that the other guy has. As you can see from my photos, I have smaller fans. Two 60mm. Two 92mm radiators on my processor. Standard exhaust with a diameter of 92 mm. You can easily cut it with regular household scissors ✂ which is what I had to do. I stuck them behind the intake fans and radiator. My pace is still the same. No changes. Only time will tell how much they really help. And how often do you have to clean them. I will add in the future.
