This selection of suppliers found at these Web sites is frequently updated and not intended to be a comprehensive listing of all heatsinks that support AMD Opteron processors.
5.3.2Thermally Tested Populated Chassis Server Solutions for AMD Opteron™ Processor
AMD internal labs have tested the thermal performance of the server solutions outlined on our
Web site at
EMEA, please visit http://www.amd.com/opteronhardware. A thermally tested server solution is defined as chassis, heatsink(s), motherboard, and power supply. This testing is strictly limited to a thermal evaluation under AMD’s internal tests for AMD Opteron processors at speeds to be released through the end of 2004 and does not include electromagnetic interference (EMI), or other component testing or considerations. Furthermore, AMD has not conducted individual thermal or functional testing on the power supplies and heatsinks in these systems.
