I forgot to mention that I have a GTX 460 which also raises the temperature inside my case. I gave Asrock support a link to this forum. Maybe it will help them.

I have an idea to build some isolation like in this motherboard http://pl.asus.com/Motherboards/Inte...ABERTOOTH_P67/ This could help separate warm air from the heatsink to do not touch a sensor. But its only an idea.
