Hi, is those temperatures common to the rest of the computer, CPU for instance as well as the graphics?
Also as you haven't said is this a desktop or laptop computer?
The temperature you mention is a little high for normal use if it is the graphics card and suggests that the computer could benefit from a good internal clean, dust and fluff slows down air flow preventing proper cooling.
If a desktop, cleaning yourself is not too difficult, first turn off all power to the coputer after a normal shutdown, then remove the side panel, look for dust and fluff on all the metalic fins of heat sinks, including those on your graphics card.
Touch the case with your hand to prevent static damage, then using a can of compressed air in short bursts and a none nylon small paint brush, dislodge and blow out any dust or fluff. Do not use the can of air in prolonged bursts as liquid may be expelled with it.
