Should I Use Something Other than NullCpuPowerManagement

I just got an i7 4790K upgrade to my CPU.
I'm currently using NullCPUPowerManagement as per the instructions of my old CPU (G3258).

I wonder if I need to upgrade to another CPU Power Management module.

Something like IntelCPUPowerManagement?

What do you think, since I want to utilize sleep/hibernate features.

You shouldn't need the NullCpuPowerManagement with the i7 as it has power management built into the CPU.
