When machine is asleep GPU temperature is resported as 510 degrees C #240

What is the expected output? What do you see instead?
The temperature of the GPU is reported as 510 degrees C after the machine is 
awakened from being asleep. The min/max can be reset but the graph is 
permanently scaled incorrectly on the Y axis, making all other temperatures 
difficult to track.

Could some kind of sanity check be done so that such figures are ignored?

What version of the product are you using? On what operating system?
3.2.1 alpha on Windows XP

Please provide any additional information below.
Oddly the graph only shows the maximum temperature to be roughly 260 degrees C.

This is a known (but not yet fixed) issue. As the other issue is in German, I 
will merge it into this.

This problem also occurs on my laptop with an ATI R7 M260 (switchable 
graphics), but the conditions in which it occurs may be different to the 
original poster. In my case, the erroneous temperature triggers when the ATI 
core transitions from the on state to the off state. When the bug triggers, the 
temperature remains at 511C until the core is turned back on (and when it's on, 
the sensor works correctly).

Here's a quick hack to fix the issue for me:

Note that the check would need to be reduced down to 510000 to fix the OP's 
issue, as there's a 1 degree difference.
