Coolbits was a Windows registry hack for Nvidia graphics cards Windows drivers, that allows tweaking features via the Nvidia driver control panel (including overclocking). There is also a Coolbits 2.0, with extra features. These features provided by Coolbits are considered expert-only and thus the reason they are normally hidden in the control panel.
