Gigabyte Motherboard...

[-Exi|e-]

I know that my mobo has 3 sensors on it, i know the 2nd one is the cpu temp and the 3rd one is the case temp, but what is the 1st one for? Right now im registering 23/33/33 degrees respectively (its very hot today). My mobo is a Gigabyte model 6VXC7-4X, anyone know whats its for?

I suppose that can be the sensor for Mobo temps, generally referred to the North Bridge :-)
