Toshiba P100-437 And Suse 10.3 Nvidia Heat

hello
i am a new user of linux and i made the installation of suse 10.3 because all the other distro s have not recognized the hardware of my laptop correct.
i have a toshiba satellite p100-437 t7400 cpu,2gb ram,200 gb hd,nvidia 7900gs 512mb,17 tft 1680x1050 res. everything gone fine with the installation,updates,drivers but my only problem is the nvidia card is overheating.
starts with 44 degrees celsius and in about 20 min arrives 104degrees!!! using only amarok,firefox and superkaramba.
does anybody have a solution? the cpu temp is stable at 38-45 degrees

thank you for the answers
