The motherboard supports a 5800x or 5800x3d processor. The power supply circuit only provides three voltage phases, and the components handling the heavy conversion lack heatsinks, causing them to overheat. Using a CPU cooler that directs air downward will help dissipate heat more effectively. Vertical tower coolers with front-to-back airflow tend to trap heat on the chips, leading to high temperatures. Avoid tower designs that push air backward; they won’t cool the components well. If you opt for a vertical style, ensure adequate airflow across the chips. The chips in the yellow boxes are the ones with DFN5x6 packaging, meaning they occupy about 5mm x 6mm of space. A 10mm by 5mm heatsink could suffice, or a larger one placed at an angle between the capacitors might work better. You can find suitable options here:

If you skip heatsinks entirely, consider installing a larger fan (80mm, 92mm, or 120mm) on the side panel to blow air directly over the hot area.
Reviewed the MS Industrial Iron videro, it appears the top of the case might not fit Arctic Liquid Freezer II well due to the thick radiator. Visual cues are unclear, but it could be too tight for a 25mm radius with 25mm fans. There appear to be multiple versions of the Industrial unit. Following mariushm’s advice with VRM heat sinks seems reasonable. I’d opt for a TR Phantom Spirit dual tower cooler with a round 140mm fan that has 120mm fan spacing holes for the center fan, allowing airflow underneath to reach the heat sink fins. I implemented this setup for a previous system, though the VRM originally came with stock heat sinks. I’m considering a Scythe 140mm fan I purchased over twelve years ago, but I’m unsure where to find alternatives except online, where prices seem high.
During maximum CPU usage, such as when rendering, the performance is affected.
A more efficient CPU cooler might actually increase heat buildup. If the CPU stays cooler, it could run at higher speeds more often, using more power and generating even more heat. The cooling fins help spread warmth away, but they still need airflow to work effectively. A fan that blows cool air directly onto the motherboard and the chips can improve cooling further by carrying heat away. The copper layers on the board also help dissipate heat, so overall cooling depends on both components working together.
I don’t know what to do right now. I need a CPU right away since I play games that require high CPU power. I also see my PSU is outdated and my motherboard/chips are acting up. Most of what you mentioned I get a bit confused about—I’m not sure how to set up fans above the motherboard or fix things properly.
