Symptom(s):
- high temperature
- processor is hot
Solution:
Important Note: Only a computer professional should assemble, disassemble, upgrade, or troubleshoot computers since the electronic devices may cause serious damage to the installer, the system, or its components if these actions are done improperly. Before attempting to disassemble or assemble computers, install components in a computer or troubleshoot computers, carefully review the documentation specific for the computer and its related components. Lastly, make sure to follow procedures to prevent damage from Electrostatic Discharge (ESD).
* Determine if the system worked before. Determine if there have been any recent changes. Often if a recent change is been made, the recent change is the cause of the problem.
* Do not overclock your system. Your system can become unreliable, may shorten the life of your PC components, may damage your PC components and may void your warranty.
* Verify that your chassis/case and power supply is appropriate for the processor model and frequency and the motherboard you are planning to use.
Chassis considerations:
*Systems based on the Pentium 4 processor in the 478-pin package must use chassis that comply with the ATX specification (revision 2.01 or later) or microATX specification (revision 1.0 or later), depending on the motherboard form factor. Intel recommends system integrators using ATX form factor motherboards to choose a chassis that complies with the ATX specification (revision 2.01 or later). Likewise, system integrators using microATX form factor motherboards should choose a chassis that complies with the microATX specification (1.0 or later).
- Pentium® 4 processors based on 90nm manufacturing process require a lower fan inlet temperaturet than previous revisions of Pentium® 4 processors. The best known method to accomplish this is for system integrators to utilize Thermally Advantaged Chassis.
- The internal chassis temperature for systems based on Pentium 4 processors 3 GHz (and above) should be maintained at 38°C (or lower) for chassis in the maximum expected external ambient (which is typically 35°C). Most chassis designed for the Pentium 4 Processor use extra internal chassis fans to improve airflow.
- Intel tests chassis with the boxed Intel Pentium 4 Processor and the Intel® Desktop Boards for minimum thermal requirements. The tested chassis list can be located at http://www.intel.com/go/chassis. These chassis meet Intel's processor specifications with the Intel Desktop Boards. It is strongly recommended that system integrators perform thermal testing on the chassis selected for each configuration of Pentium 4 processor-based systems, even when using a chassis on the tested chassis list.
*If applicable, verify the voltage settings for the processor.
* Verify that your thermal solution for the processor is adequate for the processor and frequency of the processor.
* Check to see if your system feels warm and check the processor for overheating. NOTE: Use extreme caution when checking for heat, since you can be easily burned. Many people may be running a software package or using their BIOS setup program, which is telling them the processor is running warmer than normal. Many times, these programs and/or BIOS setup programs may be wrong. Therefore, if you not feel a large amount of heat coming from the processor and heat sink, then the processor is probably not overheating.
* Make sure that the power supply fan is running properly and any other external case fans are running properly. Make sure that the air intakes for the external fans are unobstructed and have at least several inches away from walls and other items.
* Make sure that you have power cable for the fan connected to the correct fan header specifically for the processor. Refer to your motherboard documentation for more information.
* Make sure the fans on the processor are connected properly and running.
* Make sure that the thermal interface material or the thermal grease is applied properly.
* Disable thermal measurements and power saving features in the BIOS setup program.
* Update the system BIOS to the newest version. This will often correct problems with how the system measures the processor temperature.
t38 degree Celsius T ambient (Ta) or fan inlet temperature is required for the Intel® Pentium® 4 processor Extreme Edition or Intel® Pentium® 4 processors based on 90nm. See Datasheet. A 38oC Ta chassis is considered the best method to achieve this requirement
