In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.
Graphics card temperatures typically range from 30c to 40c at idle and from 60c to 85c under load. Most high end video cards typically have a maximum temperature between 95c 105C, at which point the system will shut off to prevent damage. A video card is not considered to be overheating until it exceeds 90c under load. At this point, artifacting may start to occur up to the point of thermal shutdown.
and gfx card temps are always higher than cpu temps. its natural. and not all gfx cards support temp and fan speed sensing chip. it would be more helpful if you post the make and model of your gfx card. well i meant to say that the heat from my graphics card is heating my cpu heatsink..and my gfx card is an x800 agp.
