This guys got a problem with his cooling. My 14700K idles about 10 degrees C above ambient.

14700K all the way.

I’m using a NH-U12A air cooler and temperatures when gaming are around 60 degrees. You’ll get lower temperatures if you have a 360 mm AIO.

I upgraded from a 12600K to a 14700K. I also have a 4080 (and the same case). Definitely worth it as it will allow you to get another 3-4 years use of your motherboard and RAM. And don’t believe all the negative reviews - the 14700K is a very good CPU especially if APO becomes more widespread.

I have my 14700K limited to 253W. Unless you bought your CPU only to run benchmarks 24/7 you won’t notice a difference in performance. It will use less power though which means less heat. When set to 253W my CPU will run at 5.5GHz in games on all cores so still a beast.
