Zalman has been a popular name in aftermarket cooling solutions for over a decade now. Its best known products are aimed at processor cooling, but the company also provides quiet power supplies, water cooling systems, chipset and graphic card cooling solutions. The latter is what we're looking at today with the VF3000A, a heat sink kit for AMD Radeon 5800 series graphics cards. Zalman's products usually aim to reduce noise and/or temperatures, and with the VF3000A, both goals are targeted thanks to manually adjustable fan speeds through a single knob that controls a pair of 92mm fans that sit atop a finned heat pipe structure with five heat pipes. Aftermarket heat sinks such as this are generally bought to reduce video card operational noise or temperatures to a much more comfortable level, and since some manufacturers are now allowing the installation of aftermarket heat sinks, you no longer have to worry about voiding their warranty in those cases.
