Temperature of ATI AMD Radeon R7 M265 Series (Dell) in a Inspiron 7548 laptop reading 511C!! Help!

This is obviously not true, but i was trying to get to the bottom of a noisy fan issue, and i think this misreading of the graphics card might be culprit.   

I have updated the latest gpu drivers and ran the dell detect with no new drivers returned.  Still programs like Speccy and Speedfan are giving me this 952 F  reading, which would melt into a puddle if it were the case. 

I am trying to stop the fan in this laptop to stop continuous preparing for take off fan noise when i am browsing the internet, it cannot be taxing the hardware this much.

Any replies or suggestions for this issue would be greatly appreciated.

Thank you

Kevin
