You can try, HWmonitor. Also go into Catylst Control centre and go to the overdrive for your card, you should be able to see temps there.
If not I would say there is something wrong with your card, or drivers. Try reinstalling drivers.
No i tried looking for the temperature there but it showed 0
Try HWINFO.

Post back if that shows your temps.
Also there is a rare batch sometimes that have sensor problems, so other than that I think your card has some defect.
Although also try reinstalling drivers.
-good luck
