The 412S has been proven and it is normal, it is efficient, well finished, not too bulky for a mere $ 35 approximately. Its only downside is not being eccentric and therefore the fan, if to the right, is above the memory. The fan is adjustable in height, but be careful before you buy, if you have the memory with a very large sink (like Corsair Vengeance) you have to put the fan on the other side otherwise it would be too reassembled. Its height of 160mm ensures compatibility with the vast majority of boxes.
