Question PC working after disabling Enhanced Intel SpeedStep Technology (EIST) and Enhanced C-states (C1E)

Hi everyone! So basically I have a friend who’s brand new PC was constantly freezing when at idle, but worked perfectly fine when gaming. After some researching, he tried disabling the Enhanced Intel SpeedStep Technology (EIST) and Enhanced C-states (C1E) in bios, and it worked! Now his PC isn’t freezing when at idle. However, this makes the CPU run at high frequencies at all times, which of course isn’t good as a long term solution. My question is, since this solved the problem, how can we solve the issue without having to disable these settings? Does this means that the CPU isn’t working right at low frequencies and needs to be replaced? Or maybe we need to update bios to the lastest version? Thanks for your replies!

Here are the specs btw:

- i5 12400f

- B660M DS3H AX DDR4

- Corsair Vengeance 3200MHz (2x8)

- Samnsung 970 Evo Plus 1tb

- RTX 3070

- Corsair RMx 750w

You could go into power/advanced settings and under processor power management set your own minimum at rest percentage to see where you can make the freezing at idle go away.

Do you think that the problem is directly related to the CPU? Would you recommend RMA the CPU for a replacement?
