for you i guess it is.
i like coolbits, myself. but i did have the problem with it dissapearing once, and once i uninstalled 93.71 drivers, it worked fine. so i think probably that the drivers are the problem, not coolbits.
and like i said, coolbits works within your nvidia control panel that you access on your desktop, and that is pretty handy.
