GTX 860 drivers

hello guys,
i used to use Windows 8.1 then i installed fedora 21 but after installation and while using the laptop i noticed that the laptop temperature increased and the fan works continuously and after searching on internet i knew that this problem is because i didn’t installed NVIDIA drivers and i didn’t find a solution for this problem so i returned to windows again
i knew that fedora 22 is released and i want to use it but i have a fear from facing this problem again so what can i do to install a stable version of fedora 22 and keep the temperature of the laptop fine ??
my laptop is Lenovo Y50-70 with NVIDIA GTX 860
