Help: graphic glitches when high CPU temperature (easily above 100 C)

Dear Mac Lovers,

Okay I know its normal macbook pro's temperature blows the ceiling as mine does but now it is surpassing what my macbook pro can handle. let me explain what i mean.

My macbook pro does a good job limiting the temperature to 80 C when i play games such as World of Warcraft and Diablo 3. Now the temperature is above 100 C the moment i log into the game. This causes the graphic to glitch every second or two.

i thought it was weird so i opened my laptop and cleaned inside (even though i did it within this month already) to make sure nothing "new" is in my laptop but same thing happen.

to test if its not a bug or something from the game i tried other easy games (tetris and solitaire) to see if the temperature will rise and sure thing it did (went to 105 C max while maintaining a 98 C average) when before it will never go over 70 C.

i thought this was weird so i next tested with youtube and yes it shot up 90 C when it never did this before.

the fan does work i hear it blow hard (5700 rpm)

i dont know if this will help but it "started" when i saw my laptop indexing in spotlight. i turned it off cause i was doing work at the time and then indexed it after i finished my work.

can somebody help me or suggest what to do? it really sucks when the graphic glitches every 1, 2 seconds making my eyes tired and even dizzy.

long story short: Temperature shoots above 100 C (when it never went over 80 C) causing graphic to glitch.

thank you in advance

 

macbook pro year 2009. just to clarify glitching as in the movement is not fluid. for example while i make my character run forward, it'll run and every second or so it'll be in slow motion or sometimes stop then back to normal fluid motion then slow motion (or sometimes stop) the next second. its just not "fluid" where at 80 (where it normally is) everything moves fluidly.

it sucks cause i'm not in apple care anymore... had this laptop for 4 years and forgot to extend it

 

i cleaned it good early in the month and cleaned it again yesterday when it happened so i really doubt its the dust problem...when i opened it yesterday there were minimal dust too ><

 

oh no at all everybody has questions as i am the same. i cleaned the inside of the laptop and inside the fan too ><
