Korean Patent Application No. 05-45737 Korean Design Applications No. 05-15303, 15304, 15306, 15307, 17970, 17971 Patent applications pending in over 20 nations around the world including USA, EU, and Japan. The maximum weight for a cooler is specified as 450g for Intel Socket 775 and AMD Socket 754/939/940. Special care should be taken when moving a computer equipped with a cooler that exceeds the specified weight limit. Zalman is not responsible for any damage that occurs when moving a computer. Fan rotates at 2,600rpm when directly connected to 3-pin header on motherboard, without using a FAN MATE 2. Zalman Tech is not responsible for any damages arising from using the product outside of its intended purpose. CPU and/or motherboard may become damaged if the product is incorrectly installed. Familiarize yourself with the ¡°Installation¡± steps before installing the product.
