Asus z590-E Rog Strix Wifi PCH operates at 65°C during idle mode.
PCH operates more when gaming lightly, though much of its function isn't tied to that. It manages USB ports, SATA drives, I/O, possibly lower PCIe slots, etc. Gaming could slightly raise temperatures, but it stays safe. The 65C might run a bit warm, which is normal since the PCH is naturally cooled. In short, don't be concerned.
Asus PCH handles temperatures up to 108°C [Z590]. Asus ROG Maximus XIII Hero features PCH designed for high heat resistance. Page 3 highlights this capability.
