This beautiful product is designed specifically to replace the cheap heatsink/fan combinations which are commonly provided with high performance graphics cards.
Fourteen fins made of pure copper are folded almost flat for maximum space efficiency, and the ends clamped tightly between two aluminum blocks. Two super-strong hex-head bolts are used to
compress the fins together in a multiple-layer aluminum/copper "sandwich" and rounded nuts tighten the whole assembly to very high torque level for maximum heat transfer.
Bore holes are cross-drilled through the block for extra airflow, and finally the contact surface of the heatsink is milled completely flat and polished so you can see your face in it! The heatsink is mounted directly to the graphics card in place of the factory HSF using two-part thermally-conductive epoxy (supplied). Detailed installation instructions are available on the website and an abridged printed version complete with colour pictures is included with the product itself. The design ingenuity and build quality of this product are awesome!
Product features
-
Reduces video card noise to zero - operates in absolute silence
-
Compatible with virtually all video cards
-
A fan is not required, so no vibrations are transmitted into the video card PCB, enhancing long-term reliability
-
Reduces power loading through the video card and computer PSU
-
Reduces dust build up on the video card for more pleasant servicing and again enhancing reliability
-
The graphics processing unit (GPU) on the video card runs cooler and potentially more stable even under extreme 3D processing
-
Because of the lower running temperature, video card overclocking becomes easier (overclocking is undertaken at your own risk)
Installation considerations
Please note that because of space clearance required, you will be unable to insert a PCI card in the one slot adjacent to your video card after installing this heatsink. Other slots are unaffected. Also note that a small amount of discoloration of the copper fins may occur after several years. This is normal and cooling efficiency will not be significantly affected. Finally, please bear in mind that epoxy glue supplied with the product is a permanent fixing solution and the heatsink will subsequently not be easily removable.

Video Card Compatibility
This is usable on all brands of video cards.
- For Geforce 256 DDR, Radeon DDR, and higher classes of video cards, the
ZM17CU must be used with a 92mm fan mounted over head with a fan bracket (ZOFBA)
- If the heatsink is in opposition with some video card components, do not
attach.
- The heatsink, once attached with adhesive, cannot be removed.
- If adhesive contacts skin, promptly clean off adhesive with water.
