Fast raising GPU temperature

Hello,

I have recently bought the GTX 550 to replace my GT240 1GB.
For some reason the GPU temperature gets at a fast rate hot, but the game (Skyrim,MW3) keeps runing at 60/70 fps.
But when it reached 82c the GPU starts to make allot of noise.
So is it normal for a 4 days old GTX 550 TI to be 82c in like 15 minutes.
I have asked this question before, but never really have got an answer for it :s
So is 82c degrees safe for the GTX 550 TI, because I mean yes the game runs good but I do not think that ''frying'' a new GPU like that is good, unless the GPU is made for these kind of circumstances.
