You're facing a tough decision with mixed opinions. Some users warn about overheating risks, while others believe it's manageable with proper setup. Given your good airflow—three 14 cm fans front, one in back, plus two Corsair H100i Pro units—it looks like you have a solid foundation. Whether to upgrade the motherboard or stick with the processor depends on your priorities: stability or performance gains. If you're confident in your cooling setup, going for the processor might be the safer bet. But if you want extra peace of mind and higher performance, upgrading the board could be worth it.
Ensure good airflow around the VRMs, which should help manage their temperatures. The AIO radiator above can assist with exhaust and keep things running smoothly.
