Well, did you try to run a 'top' in a konsole terminal or to run 
'ksysguard' (ctrl + esc) to check if there is a process eating the whole cpu 
time. This would explain why your cpu is eating and then why your fan is 
running fast to cool it down.
If find the guilty process eating all ur cpu time, you can then find the 
If the fan continuous run is not caused by a 'furious' process there is 
another solution : You can monitor cpu temperature and fan speed by 
installing lm_sensors (run sensors-detect to configure it) and ksensors (or 
gkrellm). if ur sensor chip is able to, you can also use /etc/sensors.conf 
(in lm_sensors package) to set the fan speed according to cpu temperature.
