So I come (04/05/15) to mount it on another socket. I still maintain my 2 stars. I do not like this kind of fixation on the motherboard, I trust too mas I prefer the screw. But hey at this price ... But what bothers me most is the noise .. Too noisy. I even want to turn on my pc ... I decided me to change the fan Noctua NF-by A9X14 PWM with PWM at that. I do not regret it. It make up the price of cooler, but this time it's silent.
