In fact, there is. Zalman's ZM80A-HP graphics chip cooler hasn't been validated for use with NVIDIA's upcoming GeForce FX, but the ZM80A-HP is a completely passive cooling solution for today's top commercially available graphics cards. Without moving parts, the ZM80A-HP promises to be impervious to fan failure and completely silent. It looks pretty slick, too.
Is the ZM80A-HP a worthy graphics chip cooler for an enthusiast's high-end graphics card? Join me as I examine the ZM80A-HP's impact on system noise levels and its ability to dissipate the heat generated by stock and overclocked graphics cards from ATI and NVIDIA.
Passive cooling solutions are usually pretty simple affairs, but the ZM80A-HP is quite a bit more intricate than even most active cooling systems. What's in the box?
First, the big stuff. Zalman's ZM80A-HP uses two massive passive heat sinks to radiate heat away from the graphics chip. A U-shaped copper heat pipe connects the two heat sinks, helping to share the cooling load between the two.
The copper heat pipe gets sandwiched between the passive heat sinks. Zalman includes two different block sets to accommodate mounting hole patterns on GeForce4 and Radeon 9x00-based graphics cards, and users may be able to install the ZM80A-HP on future graphics cards, as well.
Both the mounting blocks and passive heat sinks have grooved channels to sandwich tightly the copper heat pipe, which is long enough to accommodate even NVIDIA's behemoth GeForce4 Ti 4600.
Zalman includes all sorts of screws, nuts, and washers with the ZM80A-HP in addition to a tube of thermal compound. They even include extra thermal grease and a set of spare screws should a thick, shag carpet ingest one of the tiny screws. As if that weren't enough, Zalman also throws in a screwdriver. Everything a user would need for installation is right in the box.
