You're probably wondering why I'm asking for metal fans, here is why. I hate all these d##n computer plastic fans because they all have the same problem, they smell bad… For instance, if your computer has been running in a humid basement for a while your computer fans will keep on running with a humidity odor for years and years no matter how hard you'll clean them. I tried everything I could to clean my computer fans in order to make them odorless like they were when they were brand new. I even used pure bleach and pure Vinagar but they kept their humidity odor and this is totally annoying. T
