I have HP ENVY dv6-7357se laptop i was running windows for about a year yesterday i switched to ubuntu <3 but i'am facing an always noisy fan and heating of my laptop
with windows i never faced overheating problems today on ubuntu my laptop turned off because of heat (i was only using vlc and firefox).
maybe it could be an incorrect graphics card ?
any ideas ?
EDIT: here is my laptop's specifications except i added 4gb of ram now it is 8gb.
