Have been using one of these for over a year with no problems on my PRUSA MK2 which has been upgraded to MK2.5S. The second is in the box as a spare until needed. This fan works well enough for a parts cooling fan without overcooling the hot end, which can happen with this printer model, especially if there is a heating issue. The fan works well, but sometimes the control logic changes the speed a bit, which is audible. The fan is certainly not to blame! In short, it works well, isn't overly powerful or noisy, and has lasted quite a while so far.
