The reference is lohgue, well it is because the product is very big. Top quality, high-tech cooling, BUT Be careful how you will incorporate tower. Indeed, once placed on the motherboard, then your motherboard, your case will close IF there is no ventilation in the côtéd'installation. For example, do not provide this cooling with Advance 8702B Turboost case. I took out the 30cm fan outside (nothing too serious) and everything works fine. Cooling is optimal.
