Why are synthetic tests relevant? We use the computer for games and applications. For that we chose a "be quiet! Dark Rock 4". It has a fan and why should I use water for electronics, it doesn't make sense. Instead, we have a lot of case fans. The CPU only gets warmer than for the invitation.

Hello I'm too late but you have to change the cpu frequencies in the bios and set it to the base value + 0.25 and after that the cpu will never exceed 50C. Flemme d'explique mais en gros les fabriquants sont des gros c*n et veulent gagner sur les benchmark par rapport à leur concurrent donc il mette que le cpu essaie d'atteindre la valeur max atteignable sur un SEUL cor but la ils mettent sur TOUT les cores ce qui donne des voltages abusée qui abime votre cpu dans l'durée et créé beaucoup de chaleur.

Unfortunately, I haven't done any benchmarks yet and only measure the CPU heat when gaming, etc.
75°C was the maximum I have ever seen. I have installed a Deepcool AK620; similar to the Noctua...

In any case, use an AIO cooling system with at least 2 cooling fans. Unfortunately, I can't provide you with any data, but so far there has been no noticeable throttling. Your cooler distributes the heat in the case and also slows down other parts such as RAM, graphics card, SSD, etc.
