With any intel cpu from 12th gen and afterwards, idle power draw should be around 3 to 5 watts and browsing the web or doing simple spreadsheet work etc should be between 8 and 15. That’s if you have set up C states properly and balanced power plan.
My 12900k with 2 videos streaming (YouTube and twitch) browsing the web while on a discord call is below 10 watts.
Nobody can tell you that, and it entirely depends on the amperage going through your cpu, temperatures are not that important. If you are running prime 95 pulling 400 watts at 100c I don’t think it will last more than a year.
Define damage. Just using your cpu for anything basically damages it. Electromigrarion happens even at 50c while your cpu is idle. Obviously higher temps and higher amperage accelerates it.
The question is why would you want to run it 24/7 at 100c? Set an 80c power limit and you are good to go.
Intel cpus are incredibly easy to cool, but at the same time it left without any power limit they will literally draw up to 400 watts in multithreaded workloads. I’m running a U12A on a 14900k and it works like a charm, but again, it depends on what your goal is. By maxing the fans and letting the cpu get to 100c I get around 43k in cbr23. That’s both loud and hot. But on the other hand, dropping to a score of 40k will bring the temps down to 80c and the fans are just chilling.
If your ram was running fine at 7200 on the same motherboard then obviously the problem isn’t the motherboard as some people are commenting. Try to play around with SA and VDDQ voltages, sometimes lowering them does the trick. 1.45v is excessive for those speeds, I need 1.30 for 8000 mhz so…
There is no cpu that needs an aio. I have a U12A on a 14900k runs great.
