Touch your laptop, and that's the best way to tell if it is over-heating. From the temperatures that you post, it's a bit high. Keep your laptop on a hard surface while using it, rather than on pillows or beds, to maintain proper air-flow.
d air flow isnt block. Actually, before the time that i cleaned it, the temperature was 50-70. Then the temperature goes hot after i finish cleaning the fan. idunno why, but i think the reason was the heat sink sticks with the processor. I hav no thermal paste, sorry for my english. im only 14 yrs old
. Btw thanks for the reply
