Catalyst Control Center no longer providing accurate temps

[Sonikku]

CCC has worked for a long time. But now whenever I open it and go to the overdrive tab to see how it's doing the temp seems locked at 47c and the fan speed is always appears to be 40%. This isn't accurate, as other utilities like speedfan will show. No matter whether I'm idle or running a game it always shows the same 40% fan speed and 47c core temp on my radeon 7770. What could be causing it to become "stuck"? Closing it and reopening it seems to do nothing to solve it.
