Any way to have CPU temperature in the menu bar? I tried SMC fan control and Temperature Monitor but it does not update the temperature and I do not wish to change the fan speed.
Temperature Monitor was last updated in 2009. So maybe it is not compatible with your OS. 

I recently abandoned the fantastic MenuMeters (free) for iStat Menus 5, since the later provides even more info on practically all Mac sensors. Hardware Monitor and System Monitor are also capable of showing sensor information in the menu bar.
