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.
Anything below 90C would not damage the card. The ideal is to have it below 80C and the best is for it not to run over 70C. Your card is alright, though at web browsing 40C is a little hot. It could be the batch of card your seller received has a bad cooling card. It should be fine. Don't worry about temperature until it reach over 80C and around 50C when idle.
