PC Stats has posted a Vantec Mach 1 MP4-7015-FC Athlon64 Heatsink Review

There are heatsinks made for low noise computing, for overclocking, and then there are those built at an affordable price point which try to do both. The Vantec Mach 1 heatsink is such a heatsink; it's inexpensive and includes a sliding fan speed controller which adjusts the fan from 2800-to-3800RPM. The Vantec Mach 1 heatsink is compatible with sockets 478/754/939/940 thanks to a retention frame that accomodates both AMD Athlon64 and Intel Pentium 4 heatsink mounting spaces.
