    Intel Core i7 3630QM Safe Temperatures and TJMax

    Inzam Ahmed

      Hi. This is my first post here, so forgive me for any mistakes or if this is in the wrong section.


      I recently got an Acer Aspire V3 - 471G. It comes with an Intel Core i7 3630QM.

      Now, the thing is, this laptop is fourteen inches. A rather mid to high end CPU in this small laptop causes high temperatures.

      I know that the TJMax is 105'C. With turbo boost enabled, it easily reaches 90+ (99'C maximum, as that is when the fan really starts spinning fast).

      Other than that, the fan is quite, well, silent. I use this as a desktop replacement, and don't care about battery life.


      --Are these temps dangerous? How will they affect CPU lifetime?

      --What is TJMax? I understand that it is a maximum before the CPU throttles or shuts down, but is it the absolute limit or is it the maximum at which Intel wants the processor continuously running?


      I searched everywhere, no results. I hope my questions will be answered here.

      Thank You.

          Hello Inzam Ahmed,


          Please run the following application to stress out the processor and monitor with software what’s the max temperature reached during stress.


          Intel® processor diagnostic Tool:



          Now, confirm what the temperature is in idle.


          It’s known that high temperatures reduce the lifetime of each part of the unit and may affect software executions.


          However, most of the laptops come with fan control software that may help you optimize your unit to be properly cool down.


          About Tjuntion, it’s like you pointed out the max temperature that your CPU can reach. In case that it overpasses this measure it will automatically shutdown to prevent damage to the unit.
