i7 975 - max operating temp

I'm reporting CPU temperatures of 76C on a particular system, while running at 100% (Win 7 64).

 

I've found several references online to different recommended max operating temperatures, but no hard specification.

 

FYI: I'm using SpeedFan to pull the CPU temp.

 

Does anyone know what the max-temp of this processor is?

 

We have another system that runs at 57C, so I'm trying to determine whether to dig in and look for hardware failures.

    What we have available is the processor’s Thermal Specification.

     

    The thermal specification (also known as TCase) for your Intel® Core™ i7 processor I7- 950 is 67.9°C: http://ark.intel.com/products/37153/Intel-Core-i7-975-Processor-Extreme-Edition-(8M-Cache-3_33-GHz-6_40-GTs-Intel-QPI)

     

    The TCase is a number established by Intel® as a point of reference in order to understand what could be expected as per normal processor temperature.

     

    Anything from the Tcase and below will be the expected temperature of the processor in normal use, anything that doesn't stress out the processor (watching movies, burning CDs, browsing the internet, creating documents, etc.) When the processor is stressed out meaning that you are running heavy processor applications that take control of the CPU or uses it at 100% the temperature will go beyond the Tcase. It can perfectly reach 90 to 95 degrees and the processor will still be OK. The cooling fan is in charge to keep that temperature there.

     

    If the processor temperature reaches 100°C or more it will send a signal to the motherboard to shut down to prevent mayor damages and most likely it won't be possible to turn the computer back in until it cools down.

     

    The normal processor temperature will depend on the chassis type, the hardware involved and the location of the computer, and it usually is lower than the Tcase.

     

    Third party software results are not supported since it is very common for this tools to provide inaccurate results since usually this is not fully optimized for any processor in specific; it is more generic. We recommend you consulting with your motherboard manufacturer for an approved monitoring software.

     

    Please feel free to run the Intel® Processor Diagnostic Tool which will let you know if your processor is properly operating: http://www.intel.com/support/processors/sb/CS-031726.htm

     

    Furthermore, you may want to make sure the motherboard in use has the latest BIOS version loaded for a proper processor recognition.

    What i know off speedfan is that it was not updated in ages.

    I would try coretemp or realtemp to see whats up.

    Also most mainboards have an option in the bios to see what the current temprature is.

    Keep in mind that in the bios all cpu thermal options are turned off.

     

    76° with a Tcase of 67.9° tells you that the cpu is running above its save temps.

    Do it could be that Speedfan ads like 10° ...

    In that case its still running pretty hot.

    I would sugest you check your fan and headsink,case for dust and such.

    If that not solve's the problem leave a pannel of the case to see if temp drops.

    If it does u need better case ventilation, the build up heat cant get out off the case, heating up the rest off your hardware.

    hi if u using 100% resources of your pc ram and cpu and is just 76 C I think u ok. Posting the pc specs would really help to know more how to help ya but, if the pc keeps working and theres no much lag or unspected restarts u doing ok. 

    I would recommend check the fans directions (air flow), and how old is the pc. the thermal paste gets old
