CPU at high temperature!?

Question

Hey guys, I have a problem with my computer.
Just recently, my computer turned off all of a sudden. When I turn it on again, it works fine but after a few minutes, it turns off automatically.

I searched online for the cause and using speccy, I have found out that my CPU is overheating.
Here are the specs:

CPU
		Intel Core 2 Quad Q8200

I have done some research and the recommended ones are:

Scale 3: Quad
Q9x50: Tcase Max 71c, Stepping E0, TDP 95W, Idle 16W
Q9x50: Tcase Max 71c, Stepping C1, TDP 95W, Idle 16W
Q9400: Tcase Max 71c, Stepping R0, TDP 95W, Idle 16W
Q9300: Tcase Max 71c, Stepping M1, TDP 95W, Idle 16W
Q8x00: Tcase Max 71c, Stepping R0, TDP 95W, Idle 16W
Q8200: Tcase Max 71c, Stepping M1, TDP 95W, Idle 16W<--Q8200
Q6x00: Tcase Max 71c, Stepping G0, TDP 95W, Idle 16W

-Tcase/Tjunction-

Tcase = CPU temperature
Tjunction = Core temperatures

It occasionally reaches 90-98 degrees Celsius. Why is this the case?
I usually can leave it on for 15 hours without it overheating and I have had this computer for almost 2 years.
All fans are working, like they do per usual.
I'm actually using a big fan cooling down my computer (without the lid on) but it seems to have no affect.

Any solutions guys?
Could someone also define the word overclocked? I don't really understand it. I'm horrible with computer colloquialism.

Your system is NOT overclocked.    The stock speed of a Q8200 processor is 2.33 GHz, which is exactly what you're running.   Overclocking increases the frequency to get more computing power out of a processor - but it also generates more heat in the process.

83 C is hot for cores.   If your cpu fan is running, hopefully at max speed, then you'll want to turn off your computer and check if the heat sink fins underneath the fan are filled with dust.  If so, clean it.  Bad airflow is the #1 cause of overheating.  

Another possibility is removing the heatsink and not properly cleaning and reapplying thermal interface material.   Heat doesn't flow rapidly from the processor to the heatsink if some sort of heat conductive material isn't placed between them.

If the fan itself is working, I would question the thermal grease that is supposed to transfer heat from the processor to the heatsink (which the fan cools).

Are you doing a lot of work to warrant such a hot processor? It is possible that some unknown process (or virus) is doing work behind your back.

Also check the airflow inside your computer. Blow away any dust on heatsinks and vents with compressed air, verify that case fans are blowing in the proper direction (usually outward for rear and top fans, inward for everything else), and that cables or other obstructions aren't trapping heat. Keep in mind that opening a case can sometimes disrupt the airflow, or cause heated air to flow back into the case.

Overclocking is when you use BIOS settings (or special programs) to increase a processor's performance beyond its normal operation, by increasing voltage, clock rate, and others. OCing almost always increases heat, and sometimes requires more cooling power than a stock fan can supply. Unless you made changes yourself, your system probably isn't overclocked.

balanse · Answer

Overclocking is the setting where you push your computer's processing time to the limit.

Basically, when you purchase a processor it indicates a speed. In the BIOS (Basic Input Output System), you can modify the speed of the processing time of your processor.

The higher the speed the faster it will get HOT.

So, if you're processor is OVERCLOCKED. I recommend you to add a CPU fan or any cooling device to you're unit so it will prevent the sudden turning off of your unit.

it might be worth trying to put new thermal paste on the cpu to transfer heat better to the heatsink, you remove the heatsink and clean off any paste that is there from the heatsink and the cpu, then apply new paste as directed on the paste packaging and refit the heatsink, there is one paste called arctic silver or something like that and that is supposed to be the bestfor heat transfer, also clean everything so there is no dust in the fans, heatsink etc, you might try ther cleaning first to see if that helps
