With live-cd or hdd installation of Kali-Linux 1.0, I got my laptop fan run constantly (Vostro 3350) and make lots of noise and heat.
It turned out that this issue is with graphic card GPUs as vostro has two GPUs (http://www.notebookcheck.net/Review-Dell-Vostro-3350-Subnotebook.54680.0.html) (Intel and Radeon) and Radeon drivers are buggy (http://askubuntu.com/questions/94852/disable-ati-radeon-hd6470-in-dell-vostro-3350-and-use-integrated-intel-in-core-i) . using lm-sensors and sensors-applet the radeon temprature was constantly at 63c and this kicked the fan at high speed.
One alternative to fix this is to disable modeset on radeon:
/etc/modprobe.d/radeon-kms.conf
options radeon modeset=0
reboot, and after while fan stops working when you are on battery. Currently with wifi on I have around 4:30 hours battery (You should also setup laptop-mode-tools for power saving.)
Fans goes on and off every now and then but it is way quiter than before.
