The driver for the Radeon chips is maintained by the radeon driver
maintainers, so you might want to ask at dri-devel@lists.freedesktop.org
(copied with this reply). The driver supports different chips with
different methods to read the temperature, so it might help to know
which chip is in your system (lspci -nn should tell you).

AMD CPUs are known report wildly off temperatures especially at
low temperatures. Does the temperature increase with load ?
