I'm quite new to Ubuntu, but, sometimes, when I'm on youtube, or doing something else, GPU overheats, and cooler gets very loud, until I close everything I'm doing, than after few seconds GPU gets cooler...

I've be searching on forums for this problem, but I didn't find soultion...

I'm using Dell Inspiron 15 3521:

GPU: Intel HD 4000 (I hope) and ATI Radeon HD 8730M
CPU: Intel Core i3 3227U 1.9GHz
RAM: 4GB

I'm not sure what's overheating, but I think it's the GPU

I have the same notebook. If you need your notebook to be cooler you have to disable your discrete graphics card. You can do this by following these instructions:

Run this in terminal (open terminal by pressing ctrl+alt+t )

sudo gedit /etc/rc.local

Paste these before the "exit 0" (replace george with your username)

chmod o+rx /sys/kernel/debug
chown george /sys/kernel/debug/vgaswitcheroo/switch
#Comment next line when you need to turn VGA On By putting # as prefix like this line
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

I have also created a script for fan control but if you use it be carefull because after some time it stops: CPU Fan Control For Dell 3521
