No sensors for Ryzen 2600

If i do watch sensors, I get no information about cpu temperature, but do for every other device I can think of - pcie, nvme, acpi, gpu. I saw some posts saying to manually load it87 with modprobe but it doesn’t find a device so doesn’t load.
I have a ryzen 2600 and this gigabyte b450 motherboard.
I have also tried running sudo modprobe gigabyte-wmi a couple times, where it87 seems to be found fine, but there’s an acpi warning on each attempt, don’t know what it means though?
