Computer Overheating – How to Know & What to do? Intel,AMD CPU

How do I know if my computer is overheating?

note   :
Intel® Processors have built-in thermal protection. If the processor gets too hot, the built-in protection shuts down the computer. If your computer is not over-clocked and is running under the design specifications, the built-protection can help prevent damage to your system.

Unusual fan sounds:
Most computers have two fans; one that cools the power supply and one that cools the processor. If a fan starts to make unusual whirring, clicking, clunking, or a musical sound or beep, the fan might be failing. If the fan is the problem, always replace, never repair.

Blue screen:
If a fan does fail, the computer might boot up properly but then start to overheat. The most common result is a blue screen. If you keep getting a Windows* error and a blue screen, check the cooling fan and the air flow coming or going from your computer.

Constantly reboots or shut down:
To prevent damage to components, the computer shuts down or reboots if it senses an overheating issue. The system might reboot every few minutes until the problem is resolved. This often occurs if your system CPU is over-clocked, sped up past the recommended speed limits. The BIOS usually reports if a thermal event has occurred.

Non-fan-based CPU overheating:
When a CPU overheats with all fans working (assuming all cleaning, location, and environmental temperature recommendations are met), you might need to replace the thermal compound between the heatsink and processor. The existing compound eventually hardens with time on most systems.

See a computer technician or buy a professional grade thermal compound and replace it yourself, carefully following all instructions and warnings.

High temperature:

If you use a third party software to measure the temperature or the BIOS readings, contact the software vendor to ensure the software is validated to work with your processor.

What do I do if my computer is overheating?

If your computer is overheating and it was recently built, the following tips may resolve your issue:

Check the Fan/Heatsink. Is it properly installed?

Are the push pins in the correct position and is the heatsink securely attached to the socket/motherboard?
Are you using the recommended fan/heatsink for your boxed processor?
If you are using the fan/heatsink that came in the box with your Intel® Boxed Processor, you have the correct one.
Is there Thermal Interface Material (TIM) on the bottom of the heatsink?
Intel® heatsinks have thermal material on them from the factory. If you need additional Thermal Interface Material, and have a boxed processor that is still within the warranty period of three years, contact Intel® customer support for TIM.
Procedure to replace Thermal Interface Material (TIM).
Airflow is not blocked. Move cables or other hardware that may block airflow.
Do not use more fans than are required for your chassis. More is not better.
Update the BIOS. Verify you have the latest BIOS and update it if needed.

You can identify your current BIOS version by looking at the BIOS string, which appears during boot-up. You can also display the BIOS version by entering BIOS setup by pressing “F2” during system boot-up. The main page of the BIOS setup includes the BIOS version string. For Intel® Motherboards – example, the version string GB85010A.86A.0046.P05 identifies the BIOS version as P05.
Correct Chassis. Do you have the correct chassis for the processor? A list of test chassis is available in the Thermally Advantaged Chassis List.
If your computer is overheating and it was running fine, the following tips may resolve your issue:

Check the Fan/Heatsink.
