Hi there guys

I recently purchased the 6600 GT 128 bit AGP. I would just like to know if there is a program that monitors it + fanspeed etc. I would just like to see if it is running at full capacity. Also in the settings there is an option to tweak it mhz etc. I clicked on "Optimal setting" which produced more mhz. Could this damage my card in any way?

Any comments appreciated.
