which software to check temperature of VGA????

I'm using Geforce 6600,when I run with heavy applications,I don't know whether how much the temperature of VGA is?????everyone can show me software to check the temperature of VGA!!!thanks very much!!!!

The 6600 cards to have a temp sensor in the chipset, but not all makers have enabled it. To tell if your 6600 has the sensor enabled:

Right-click on any open area on the desktop, Properties, Settings, Advanced, geForce 6600, Temperature Settings.

If you don't have the "temp settings" option, then your card's sensor is not enabled. The only way (that I know of) to enable it would be to modify your card's bios.

and how do u do that?
