“Good replacement for the fan on the stock case. Keeps the machine cooler and makes less noise, and you can take the lid off without worrying about what to do with the fan cable. (unplugging the fan can be problematic, it would seem that it's fairly easy to bend the connector pins!) That said, by default the CPU temp is still hotter than I'd like and it makes a little more noise when loaded than I would like. Would choose this over the case fan every time.”
