Try undervolting it. Stock voltage on these chips are overkill. The only thing I did on my 14700k is undervolt by -40mv on core and ring. 100% stable with 24 hrs of stress testing and no crashes in any games so far. and max temps at full prime 95 and cinebench 24 hovered around low to mid 70 with like a quick spike to 78c max. I am using a 420AIO. with max CPU package power staying under 270w. Did a quick throttle test on cinebench 25l4 for 10 minutes all clocks 100%. Max power draw was 248.045w. enjoy the beast
I undervolted through my motherboard bios. I am using a Gigabyte z790 board. If you don’t want to mess with BIOS you can always use Intel XTU. The program does make it easier to mess around but I always like doing it through the bios. Trying to avoid any apps if I can. My advise when playing around with voltage. Start small like start at say -30 or -40 Mv undervolt on cores and run a quick cinebench 24 multi core thermal throttle test. If cinebench doesn’t crash go down 5 or 10 mv test again and so forth. First do the cores. And then do the ring. When I originally did mine on stress test I could get it to -80 MV cores and -50 ring stable but then when I started gaming like cyberpunk and Hogwarts legacy would crash in 2 hrs gaming sessions so I went down to -40 MV on both and since then no crashes whatsoever. I am running a phanteks g500a air flow case with 6 140mm fans. The 420aio is at the front blocking a lot of incoming airflow but it’s still really staying cool in there. Normal gaming temps for cpu around 45-55 max and GPU goes around 65-70 max. Both cpu and GPU are undervolted and I actually gained performance by undervolting them both so I think it’s a must to undervolt the 14th Gen CPU for sure. Good luck playing around with it.
