Hey guys,
I'd like to thank you for this thread, it helped me on my decision to buy the MSI GS70 while looking into it's temps behavior.
I've got mine now, and it idles at
~45C.
Well, I went ahead and tested it's CPU under load with Intel XTU. Unfortunately I got it to reach
90C in the very beginning of the test, the right fan got crazy loud, and the CPU throttled to lower clocks because of the heat.
I have experience with opening laptops to clean/repaste, so I'm actually considering opening mine to see if something can be done in the heat department. I bought the computer in the USA but don't live there, so my warranty is pretty much useless since MSI here in Brazil probably won't accept products bought outside.
I'd like to ask fellow owners about your temperatures when running stress tests (like Prime95, OCCT, Intel XTU) which I know aren't "real life situations", but they serve as a good point of comparison between models.
If mine really is over average, I'll open it to see what's going on. If I do open it, I'll also analyze the fan and air intake's inner workings, to see if they can be improved in any way. MSI's pictures show the holes in the upper part as being the main air intakes, but there's also the vents under the notebook that seem to be "traditional" air intakes as well. Maybe drilling the bottom of the case would result in better overall airflow? I haven't found any mods for this model yet, so somebody has to be the first crazy one to attempt it
Also, while on the subject of heat, I'd like to recommend CPU undervolting to anyone who owns this model (or any model, really). For less informed readers, It consists of lowering the voltage used by the CPU, while keeping it's frequency values on default. So, you get less heat production, and ZERO performance loss.
Intel Extreme Tuning Utility software has the option to do that, "Dynamic CPU voltage offset".
In my MSI GS70 I was able to reduce it -100mV, resulting in total TDP decreasing under load from ~50W to ~40W, and the throttling stopped.
The temperatures are still high after the undervolt @
~87C, so I'm still up for the repasting. Any help will be appreciated!
