Yeah thats what i thought (need a probe) but i thought maybe they have them. Well thanx. And my card is an NVIDIA 5600XT I know its not a very good card but i dont game that much, mostly 3d modeling and web design and stuff like that. And i think i will install a probe on it instead of my cpu because my cpu has one already so u think i should take the probe that came with my case and put it on te VGA?
