The GPU is Nvidia 8600GS 512mb.I have it for like 3-4 years.I dont plan now to buy a new gpu because of lack of money.Only a fan i think.I did thermal paste 1 month ago..But the fan is the one that isnt working properly.It rotates,yes,but still...60c temperature on idle?..It doesnt have that temperature all the time but it still annoys me.I heard i need to oil the bearings to make it work itself,without needing me to rotate it,cuz it doesnt start itself,i need to do it.Another thing i saw is that is more harder to rotate it than before.3 Days ago i would just rotate it a bit and it would go on but this time idk what happened..
