My setup includes a very cold system with four thick fans and more than twenty fans. The GPU stays around 40°C while the CPU is at 70°C—the X3DS is getting quite hot. It’s not something I noticed before, but it seems the southbridge gets really warm on my AsRock Taichi X570.
It’s a borderline situation, but definitely risky. I’d begin to feel uneasy if it drifted into the 90s. That level of heat is unusual for a southbridge since its role is mainly I/O, not memory or PCIe management. You’d need to investigate the fan placement—those 20 fans seem mostly exhaust. Manufacturers often use inexpensive heatsinks on the southbridge, relying on case airflow, which isn’t always reliable. VRMs also tend to overheat without proper CPU cooling. If temperatures climb into the high 80s, consider adding a fan to target that component.
I have 12 fans, but where are the others? It looks like a drain port, so at least it’s simpler to drain that loop.
Absolutely, I get it. You were really confused about the exhaust setup. It looks like those fans are pointing into the case, which is unusual. For the Corsair 1000D, you should stop buying it since they no longer make replacements or anything else for it—it's a big hassle now.
