well if you are not crashing then you are fine. you can use msi afterburner to crank up the fan settings. laptops are designed to take higher temperatures. on my desktop my video card does not go over 76c
I was having these temps too on with my Alienware with a 525m. I was noticing the graphics card stuttering and dipping to below 10fps as the card tried to cool down. I took an air compresser and blew the dust out from my fan, and my temps went from 90-95c to 50-60c on load. It's simple but makes a huge difference.
fixed it....mine was reaching 90-93 degrees..then throttling begins..go to the link below and look for my name Aeonia (page 4) for the fix..start reading from there...now my temps rarely cross 79-81 degrees on 797mHZ
