4790K Volts

Okay so recently built a system using a 4790K and a Noctua NH-U12S cooler.

I haven't overclocked yet per se, instead I've used Intel XTU to increase the Turbo frequencies so that all four cores can run flat out at 4.4Ghz and this works fine. Max temps I've gotten on the CPU is 75c during heat stress test.

So what about voltages? I have set 0 LLC in the BIOS but the voltage is dynamic. Highest I've seen reported is 1.22 and this goes much lower when the CPU is C-stepping down to lower frequencies.

Question - there seems to be a consensus that a fixed voltage is better? Is there any truth to this and what, if any benefit, am I going to see if I manage to set it up this way?

Less extreme spikes of voltage when using heavy loads. With adaptive your gonna see more volts pushed through your CPU under artificial stress testing (prime for example). If you're not overclocking and your running temps are fine then there isn't much need to switch from adaptive IMO.

Only time I've seen my 4790k draw more than 1.774 is prime, where it draws 1.884 at stock this is ofc.

Thanks, so basically not much point unless OCing. No plans to push it faster at present so I shall take your advice and leave it as is.
