Pros: I have a PC with an AMD XP1800 CPU that was running 55c/64c, which is way to hot for this CPU. After installing the fan (see cons), the temperature dropped to 36c/43c, over 20 degrees C! It is quiet and is doing a great job, especially for the price.

Cons: When you first unbox this thing, you are overwhelmed by its size. It's huge! If you are restricted in space in your case, then this is not the fan for you. But if you have space, its perfect. It has a pyramid design, from big to small, with a huge heat sink and a huge fan.

Overall Review: Great packing, great workmanship, great fan.
