Linus notice me!
Anyway, I am soon traveling out of country, so a few days ago I bought myself a budget laptop to carry with me. With budget I mean the cheapest thing I could find that can at least run something.
It ended up being an Acer Aspire 5 with:
i5-8265u Whiskey Lake
8gb ddr4 2666 RAM
and a whooping Nvidia mx150 2gb ddr5! (the new sneaky slower version)
for 690$
So 2 days ago I came across a forum post about how CPU undervolting can actually increase the speed since it can cram more Mhz in the 15W throttle range and also decrease temperatures. They used a program called ThrottleStop which is simple and worked fine on my laptop (XTU won't install on my laptop claiming it is an "unsupported system"). So I went through ThrottleStop and managed to get a stable undervolt at -110.4mv on both the core and cache, and -41mv on iGPU. And thus it now holds +600-700Mhz more while inside 15W limit during Prime95.
Then I started gaming a day later and noticed something that I haven't paid attention at earlier, my temps during gameplay of Rainbow Six Siege run between 85-88°C at 60-70% load, but also I can often see them spike to 93°C for a split second. And ThrottleStop itself claims that the max temps get as high as 95°C by hitting the PROCHOT 95°C temp limit. Idle temps are at 46-55°C when plugged in and in "Best performance" mode.
So of course I freaked out a little and thought that I might have messed something up, so I reverted ThrottleStop settings to +0mV, disabled them, Turned ThrottleStop off, deleted its entire folder and .ini file and did a hard restart on my laptop.
Turns out the temperatures are still exactly the same.
I admit I am not much of a laptop guy, but I wouldn't allow my i5-3570k to ever reach these temps on my desktop. So I googled around and some people claim everything over 80°C is bound to cause problems. Some people say newer laptops run this hot normally. All I could find is A Tjunction max temp specified as 100°C on intel website, but on sites like askgeek.io or technical.city the max Tcase is listed as 72°C.
So I extracted ThrottleStop once again, undervolted my cpu and tried to lower the CPU Clock ratio to lower the clocks and thus speed. But it wont take on the change and the CPU keeps on running @3.9Ghz when plugged in and on "Best performance" mode. Also there doesn't seem to be any way to set a new lower temperature limit. I also bought a laptop cooler stand to make sure it has enough airflow, but no difference.
Since I didn't pay attention to temps before undervolting, I am not sure if I caused something or was it like this out of the box? Can ThrottleStop mess something permanently up even after completely removing it and doing a hard restart? Or are these normal temps for this laptop?
Halp! And thanks in advance.
