Can you upload a picture of your stock CPU cooler? Is the heat sink clean? Dirt can rise the temperature dramatically.
the heatsink cleaned not dirt, maybe the processor get any problem?
That is very high, but I have no idea what it's a temperature of. A new cooler will help you immensely.
Maybe i must buy 212 as you said,
. if i buy new cooler that temp3 than the temp does not go down , what i must do?
