Review on 🌬️ Noctua NH-U12A Premium CPU Cooler: High-Performance Silent Cooling Solution with NF-A12x25 PWM Fans (120mm, Brown) by King Reeves

I really believe this is the best cooling system for 95% of PC manufacturers. Cooling performance is almost the same or better than AIO, no worries about pump failure or leaking, it's quieter than AIO and small enough to work with most cases, motherboards and RAM. I even have it in my mini itx h200. If you're not using a gapless case for the CPU, you'll need something cheaper, or you'll need extreme cooling like phase switching, or maybe custom circuitry; it really seems like the best choice.
