Intel 12400 consumes more power than 7700K during idle?
Intel 12400 consumes more power than 7700K during idle?
This isn't a big deal. I don't know if it can be helped. I just moved from a 7700K W10 to a 12400 W11, changing only motherboard and cpu. Somehow I'm monitoring the PSU fan speed which is still regulated by the PSU. With the 7700K the PSU fan speed stayed always at 600rpm at idle (Arctic P14 PWM Fan ramping up to 1700rpm). Now the PSU fan speed stays at 800rpm at idle. My new system needs more power at idle (probably also at full load). While Afterburner shows around 6W for CPU and 14W for GPU. But the 12400 is, with 48°, hotter at idle than the 7700K was. (I did undervolt the 7700K from 1.35 to 1.20V because it got really hot, but this shouldn't matter) Any ideas ?

Execute the 12400f to 100c setting without issue, as you don’t have a BCLK board. It’s safe even under load reaching 100c. For reduced idle power draw, adjust the BIOS and apply a VCore offset.
But what was your operating temperature with the 7700K? I believe 48 degrees isn't a big issue if your room stays warm and you don't rely on air conditioning constantly, especially in a hotter area. I'm in a comparable climate and I prefer not to keep the AC running while sitting, since I dislike being too cold. My 13900KF reaches about the same temperature when drawing just 2-5 watts, which is minimal. I also have a 420mm AIO installed. However, my fan curve isn't very aggressive, particularly below 60 degrees. I've set my maximum temperature to stay under 85°C even during heavy load.
Around 39° seems to be the case. I’m sure the temperatures aren’t an issue—my CPU hits 80° when fully loaded, which is fine. However, it feels like I should now be paying more for the same performance, whereas I expected a lower cost. As mentioned at the beginning, it shouldn’t be a big deal, but I might have to adjust if I can fix the situation.
It really isn't that way. The gap between 39 and 47 is just a small surface difference. 39 feels similar to your body temperature, while 47 is a bit warmer. It's likely due to variations in design, size, and complexity. You might also consider trying contact frames with better thermal paste.
I understand your point of vue, I know it, I've had it. But here I have another one. It's difficult to explain. My system draws more power than it did before for a similar use. I don't care about 39° 48°, those are not related to system power draw (if better thermal paste lowers temperature it won't lower the system power draw)
I see, I missed the details about your worries regarding power usage and temperatures. It seems the PSU's fan might not be the best indicator—using a power meter could help you accurately measure draw at idle and under load. Also, consider checking your motherboard’s impact on overall power consumption and whether it’s causing the PSU to overwork. That’s likely the full picture I have right now. Please let me know if you need more guidance.
