The Jet 7 from Coolermaster is one of the more unusual models on the market.
Based on the low power dissipation produced by the Athlon at a few hundred megahertz, passive cooling even becomes feasible. The only prerequisite is a suitably dimensioned cooling element.
Many CPU coolers available on the market offer the option of stepless fan speed settings. We tried some coolers at the lowest and highest possible speeds and with the fan turned off. They were the Jet 7 from Coolermaster, the SLK-800A from Thermalright and Zalman's CPNS 700A-CU. All allowed stepless setting of the fan during operation and are thus perfect for our requirements.

A good-value model: SLK-800A from Thermalright

CNPS 7000A-CU from Zalman
