Hi guys!

First of all, i know this is on my own risk and it is me who is fiddling around with my Nvidia card. So please, no lectures!

I try to overclock my Nvidia card just for fun and experimenting. I'm running Mint 17.2 Xfce and following this instruction. But i don't see the GPU Fan setting button under Thermal Settings nor do i see the Enable Overclocking option.

My nvidia card is the GeForce 8400GS (in a desktop system connected to my flatscreen tv). Has this type of videocard a limitation for overclocking? Did someone overclock this card?

Thanks for your assistance!
