This disables CPU throttling and prevents the CPU from going into low power states. It will make the CPU always run at the 1.7Ghz speed in your example.
Some motherboards have a Windows app that allow you to do this from Windows. I don't think Lenovo has a similar tool (but I could be wrong there).
Running with passive cooling and no fans may greatly reduce your CPU speed (maybe to 500-800Mhz in your case...)
Windows can do it in power management settings. I have mine set to full speed all the time.
