about the i7 2670QM processor temperature

Hello,

I have a Lenovo Ideapad Y570, and I only had it for 2 months or so.

I do not know why, but few weeks ago when I play nba 2k12, it was running on 70's C and spikes to 80's C for few seconds (turbo boost disabled)

now, it was running it on 80's C and spike to 90's C even I disabled the turbo boost of the processor.(when I play A.V.A when I turn the turbo boost on, it spikes to 90C). GPU max was 80..

I'm assuming the thermal compound is bad or need to be reapply... I know the TJ max for this processor is 100C. I reached it once when I play the COD black ops.

basically the processor's temperature is running between 80-100C when I play game, Some said 80's is acceptable, 90s is somewhere I need to worry about..

I was wondering is this okay? will it shorten the life of the processor and laptop?

I have v2.10 BIOS

The temperatures are cooled down to normal idle temperature after few minutes when I am done with the game.(38-45C)

thanks in advance.
