These are good coolers, especially for the price. But I have destroyed two of these by not having the pin fully in the hole when you click it. It rocks back and forth and is really hard to see the holes unless the mb is removed from the case. So if you want your F7 to last more than two installs, always install it out of the case. The plastic pins on the F7 are of much softer plastic than the stock Intel pins. So they can bend sideways very easily if they are not aligned perfectly in the hole. As good of engineers as the Germans are, I'm sure this was not just an oversight...and they got $40 out of me.
