XFX7600GT Diode &PC Wizard2006

Yesterday my XFX7600gt eXtreme Edition came, and today when I decided to look at the temps with Everest (Ususally I use ATItool) and noticed that GPU diode in everest is always at 704oC.

I know this isn't true so I'm not worrying but, could this become a problem in the future??

Here's a screenshot:

I dont trust Everest. Gforce Drivers/Control Panel have temp monitoring for your card.
