This product was designed to optimize heat dissipation for excellent cooling performance. Dual heatpipes increase heat transfer speed and enhance the cooling efficiency. The fanless design ensures complete noiselessness and maintenance-free operation. RAM heatsinks for cooling the VGA RAM. Compatibility with virtually all types of VGA cards allows reinstallation when upgrading the VGA card. (Incompatible with VGA cards that do not have original heatsink holes measuring 3mm in diameter, or VGA cards on which the ZM80D-HP interferes with the card’s components.) An Optional Fan (ZM-OP1, sold separately) can be attached to the heatsink directly without using a separate bracket.

Weight : 350g Heat Dissipation Surface Area : 1350㎠ Heatpipe : Gold plated copper tube VGA RAM Heatsink material : Anodized Aluminum Dissipation material : Anodized Aluminum VGA RAM Heatsink weight :      Frontside : 2.9 g (EA), Backside : 1.2 g (EA)

This product can be used with any video cards that have heatsink mounting holes. Note 1) If you are using an nVIDIA GeForce Fx5800, an ATI Radeon 9800 Pro, a Matrox Parhelia, or a more advanced model, an Optional Fan (ZM-OP1, sold separately) must be installed. Note 2) This product cannot be installed on nVIDIA GeForce 6800 GT and 6800 Ultra because they do not have 3mm heatsink installation holes. Also, this product cannot be installed on nVIDIA GeForce 6600 GT AGP, 6600 AGP, and PCx 5*** series products. Note 3) Zalman does not recommend VGA card overclocking. Zalman is not responsible for any damage from VGA card overclocking. Note 4) Since this product weighs 350g, always firmly fasten the VGA card onto the case with a screw. Special care should be taken while the computer is being moved. Zalman is not responsible for any damage arising while moving the computer. Note 5) To enhance the performance of this product, the use of a fan on the rear panel of the system’s case is recommended. Note 6) After installing this product on a VGA card (Video Graphics Card), the PCI slot adjacent to the AGP slot will be unusable.

The computer should be placed according to the following diagrams in order for the product to function properly.   If it is set up in such a way that the video card's GPU faces upwards, then this product cannot be used. Also, if you attempt to adjust the positioning of the computer by flipping it in a reverse direction, the product will not function properly either, so you should place your computer case in its normal position.       1) Good (AGP slot is under the CPU) 2) Good (AGP slot is under the CPU) 3) Bad (AGP slot is over the CPU) 4) Good (AGP slot is on the right side of the CPU)     To Enhance the Performance   You can expect a satisfactory cooling performance with ZM80D-HP alone, but this product is also designed to accommodate a noiseless fan (ZM-OP1) on its heatsink. Therefore, should you want even more stable performance, you can attach the noiseless fan (ZM-OP1) as needed.     When installing a video card that has this product installed into a computer system, open up the PCI slot cover under the AGP slot to lower the GPU(VPU) temperature by around 4 to 5 degrees Celsius.

Video Cards with the Heatsink Mounting Holes   Installable on video cards with the heatsink mounting holes     Interference with the Motherboard Components and Other Peripherals   If the northbridge heatsink that is 25mm or taller in height (measured from the motherboard's surface) is away from the AGP slot in the direction of the CPU by 5.5mm or farther, this product can be installed.     If CNPS7000 (Zalman's noiseless CPU cooler) is also to be installed, the CPU retention guide needs to be 35mm or farther away from the AGP slot for this product to be installable.
