Problem whit my CPU temperture

The cooler being cold is a bad sign, it's most likely not seated correctly.

yea but the temperature is unchanged always 98ºC never 97 99 100 i test temperature whit speedfan

Is fan spinning really fast? Is the computer freezing/crashing/restarting?

the cooler is Hyper TX3 CPU Cooler, and have 2800rpm but no restarting and crashing... nothing :S but cooler is cold :S

What does realtemp and coretemp say for temperatures?

Ok we need to know:
Is the thermal paste the right amount? (Pea dot size)
And wiggle around the cooler a little when the computer is off to see if its on firmly. It its loose and moving around you will most likely have to check those pins. Make sure that the cooler pins all click in. You will hear the click, its ok if the mobo bends a little. If it doesnt click then take the pins out check if they arent bent and put them back in. Also, this is a major how much paste is on the cooler.

in coretemp:

Tj.Max 100ºC
Core 0 33ºC
Core 1 33ºC
Core 2 33ºC
Core 3 33ºC

Hmmm so it seems to be running ok. im not sure about the tj.max one. Have you run prime95?

no i dont instal prime95... do the test?

You could to see if theres any stability issues, but i would reccomend you check the fan pins and thermal grease first, before anything.

There's something a little weird here. It's unlikely all 4 cores are the same exact temp.Does realtemp say the same thing?

stay off my computer all night and after turning on the cpu temperature was 98 º and according to BIOS

Is your BIOS is up to date? I remember ASUS board had problems with fan controls (SC1333).

When you applied the thermal paste did you put it in the correct method?

i put thermal paste in correct method, and no the BIOS is not update because i dont do this :S im a little noob xD
