Well this is a very efficient cooler, it cools very well the processor with a minimum price, I buy because the original cooler with legs no longer hung on the motherboard (force to remove it). There is exactly the same system to attach it to the motherboard, it is a bit annoying but a good system must be there. For that price I'm not at all disappointed with the performance: my processor runs cooler than with the old CPU cooler (original). I recommend it if you need it only.
