Do all fans provide sensors data? Not all fans do so. Are all fan connectors on the motherboard have sensor chip connections or do they just provide power? What do you mean by "control": speed regulation or just getting the fan speed value? > I run 2.6.14-1.1653_FC4smp kernel and there are no fan, processor, > thermal.... modules available; are these modules necessary to control > all these hardwares and, if yes, how can I compile them for my kernel? I > read http://fedora.redhat.com/docs/release-notes/fc4/errata/#sn-kernel I am sure the kernel has the required I2C modules. Did you run sensors-detect? Did you compare the motherboard manual information about the sensors chip with the information about the lm_sensors software? > "7.2.2.4.

The Pentium IV and Xeons reduce their clock speed to avoid a burn out, i.e. if the cooler is not working properly and temperature values are left. > Last question: I cannot start cpuspeed service, how can I do that and > how to configure this service. Why can't you start that service?
