The VRMs are the voltage regulation units on the mainboard, responsible for reducing the 12V from the power supply to about 1V for the CPU. They can only manage a specific load before overheating or failing, and a 3800X will approach their maximum capacity
The data shows that significant airflow is suggested. So, it seems a cooler upgrade would be beneficial.
The guide focuses on cooling the VRMs, not the CPU directly. The parts labeled as VRMs also need airflow for proper cooling. Simply replacing your existing cooler with an AIO might reduce airflow, causing them to overheat. For better performance, choose a larger cooler from brands like Noctua or BeQuiet and ensure a fan directs air over the VRMs.
Looking for alternatives to liquid cooling? Noctua and BeQuiet offer reliable options. Examples include the Noctua NH-D15, BeQuiet H3, and other high-quality fans for various setups.
In your situation, it won't work. If you don't wish to swap your mainboard, it's better to opt for air cooling with plenty of airflow around the board.

Your motherboard lacks heatsinks on the VRM, a component that supplies power to the CPU. When the processor draws excessive current, the conversion chips may overheat. The BIOS notices this and automatically reduces the processor speed for a short period until temperatures drop. Simply cooling the CPU won’t be enough; actually, better cooling allows higher frequencies, which demand more power and cause those components to get hotter. The 3800x model has a high TDP of 105 watts. On boards without VRM heatsinks, using a processor with around 65 watts would be ideal. The chip will still run hot, and intense workloads could force it to throttle further. To enhance cooling, consider upgrading to a larger case (80mm, 92mm or 120mm) and installing a fan that directs airflow directly over the chip. Alternatively, you can add small heatsinks to the chips for extra cooling.
