Case Fan Roundup: Twenty Three 120 mm Case Fans Tested

Case fans are supposed to cool your case. Some vendors still refer to all computer fans as “case” fans. But in this review, we will use the term “case fan” to refer to a specific kind of cooling fan — a fixed speed fan designed to cool computer cases. Today we might want to call them non-PWM fans. These fans are “set ’em and forget ’em” fans (except that some of you insist on using fan controllers to vary the speeds of your fans, imagine that!). In any case (get it?) we’re going to look at 23 case fans in 33 different settings.
