Can't beat the price
Not the best style of fan, but it is definite the most affordable. It is 80mm from corner-to-corner not from center of screw to center of screw.Got this as a replacement for another spindle-type cpu fan that had got a lot of gunk in the spindle and could not be taken apart to cleaned or even oiled. Hence the flaw with the spindle-types. However, i loved the little rubber pads it came with to help reduce rattle. Even without the rubber pads, it runs quietly. Screws it came with were the right size.Only criticism is that the plastic packaging it came in was a little roughed-up. Box didn't look new, but the fan definite did. Maybe repackage? Or fell off the back of the truck? Who knows.In all, i'd gladly replace more spindle-types with this affordable model.
