This is a homepage of CPUHeat and CPUMSR projects. Those programs are for
power users only, especially CPUMSR can cause
your system harm if you don't know what it does.
We do not take any responsibility for any damage
those programs can cause you. You do everything on your own risk!
Note: Both projects are still in beta. They can show strange behavior in some
Help needed !
We need datasheets that are not available for download (eg. non-public
datasheets) and also bug reporting.

I added Intel Processor Maximum Power Consumption data. There are
currently 5 CPUs with more than 100W and 9 CPUs
with more than 90W of power consumption. In this case, power consumption is the
same as thermal power. If you want silent PC or conserve on energy, check this
