Well today I am looking at two SilenX case fans. I know what you're thinking "Hey Andrew how can fans be so special?" Well I will tell you how. The first thing I noticed about these fans was there not like most case fans where the blades are just flat pieces of plastic slightly tilted. Oh no they have a nice curve in them also they are slightly cupped. What does this mean to you? It means the design helps pull in and push out more air! There for better cooling. Also I found with both the fans is there a heck of a lot quieter then stock fans. Even more then the 240mm cooler master fan I have. Another bonus I found with these fans was that they came with noise dampening rubber pins instead of screws. I think that is the biggest assist to lack of noise. They do come with standard steel screws also.
