Hey guys, just wanted to post a little update. Now, without doing literally anything to my computer, my temps lowered a lot. The highest temps I get now while crunching for WCG are between 65 and 70 degrees, which I think are actually pretty normal for a laptop. Anyways, thank you all for your help!

Did ambient temps drop in the room? That is strange that it would lower all of a sudden without any outside influence. Maybe a dust bunny was stuck in the blower and it finally worked itself free

Something must have changed.
 Yep, maybe lost a dust-bunny, but did you move the laptop or the things around it? They can be quite sensitive to the surface they are on, smooth is good, and to having a bit of space around them, either for the exhaust or for the intake. |

I've found much lower temperatures on Help Stop TB and Microbiome Immunity Project work units. I'm sticking to those projects until the weather gets much cooler.
----------------------------------------Details: On my i3-8100 quad core desktop CPU, on any other projects like Vina (Zika and Ebola) or Mapping Cancer Markers, CPU temp running 4/4 cores would get to 67-68°C with room temperature around 29°C (84°F). When running 4 HSTB work units, right now my CPU temp is around 58-62°C.

The surface haven't changed at all and ambient temps lowered by 3-4 degrees so as far as I know there shouldn't have been that big of a change in the cpu temps. I guess the computer lost a big dust bunny without me having done anything.

When running 4 HSTB work units, right now my CPU temp is around 58-62°C. Don't know about HSTB, but I'm sure that MIP (at least older app v7.11) has not been using "advanced CPU features". So the CPU doesn't heat that much, as it's "brute force only crunching". We have been discussing here about that, that using several MIP jobs on HT CPU is a "waste of resources". Until that time it gets fixed, "open the cases". It's what I have done, to keep computer quiet!  |

Temps will be cooler with MIP due to the CPU spending more time waiting on data from main memory as a result of L3 cache being too small for this app. Known problem...

So, run MIP in conjunction with other sciences. I'll keep this in mind.

If you have Windows this might be useful to you in controlling CPU temp: https://efmer.com/tthrottle/

Ok so, small update. I removed the battery and things are now so much better: while with the battery I would have averaged 75 °C my temps now don't go above 60 °C. So, if anyone is wondering, removing the battery makes a huge difference, at least that was tha case for my laptop.
