Got the same score as yours with 4 heat-pipe air cooling and seems like there's even room for me to go higher. At full load, 100C is too high for water-cooling on just a 12600K, if I only hit 79C on a CM Hyper 212 RGB Black Edition, you shouldn't be hitting 100C with liquid cooling and just 200Mhz higher. I suggest checking your AIO, especially if its an MSI AIO as they have had recalls recently for imminent clogging and higher temps. Or getting more case fans/better airflow case, idk ur situation but yeah. Seems like you should have a lot more head-room than your temps lead on.
