VCool for FreeBSD - Cooling software for AMD Athlon/Duron CPUs
FVCool is the FreeBSD version of the famous VCool software http//vcool.occludo.net which changes the PCI configuration data of some chipsets and thus allows AMD Athlon/Duron CPUs to go into power-save mode. This makes the CPU consume a lot less electric energy, and it produces a lot less heat as well. This trick is not a secret - on FreeBSD, you can actually achieve the same effect which this software has using the “pciconf” command.
Please note that this software may have a negative impact on the system’s stability and thus should not be employed in production or mission-critical environments.
