Fan constantly running even after updates

view story

http://askubuntu.com – I have recently installed ubuntu and i have also installed Bumblebee which caused the fan to run constantly due to hybrid graphics card. I also also installed Jupiter to switch my laptop into power savings mode. Even after all that my fan is still constantly running, i believe its due to the harddrive, but i may be wrong since im not an expert. Also i feel as if my intel graphic card isint updated because videos dont feel HD when i play them. Thanks. (HowTos)
