Enable CPU Power Management
It's very easy to implement CPU PM for your Core i Intel CPU. All you need to do is place the correct
SSDT.aml for your processor into the correct folder of your installation drive's EFI partition. For the HP 6300/8300 you need to be using the iMac 13,2 SMBIOS. Find the i5-3470 and i7-3770 SSDTs attached below.
NOTE: This step is optional and not mandatory for you to implement.
/Volumes/EFI/EFI/CLOVER/ACPI/patched/
Use either EFI mounter V3 or Clover Configurator to mount your EFI partition then drag and drop the file there.
After you've done that make the following changes under the ACPI tab in Clover Configurator in the
Drop Tables section and save the changes :

If you don't have the i5-3470 or i7-3770 CPU generate your own SSDT.aml by using this guide:
Generate SSDT for CPU PM
You can also download the
Intel Power Gadget for Mac to check your CPU power usage. Download AppleIntelInfo.kext and run that via Terminal to see if you are getting all the p-states that you should for your specific CPU. See the SSDT guide linked above for complete instructions from tonymacx86.

At idle my i5-3470 stays at about 25 degrees C and only uses about 6.5W of power. That is quite impressive.
