With the new Pandemics feed I'm hoping a lot of home users will also install the WCG client and start helping.
----------------------------------------Doing that myself, I noticed WCG tends to warm up my laptops and tried to figure out what ideal settings would be to prevent that. Since setting an option that monitors the temperature isn't available in Boinc, I'd like to invite you to share your settings, if you also tried to make the setting so that the laptop keeps running optimal without additional heat (so you can still use it on your lap) and noise (by fans). In my case: * MacBook Pro (Retina, 13-inch, Late 2013) [2,6 GHz Dual-Core Intel Core i5]: 50% CPU (making it two threads), 100% CPU Time. * MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports) [2,3 GHz Quad-Core Intel Core i5] - 13% CPU (making it one thread), 50% CPU Time. (sounds quite low, but anything higher will make it warm). [Edit 3 times, last edit by DvB-William at May 20, 2020 7:18:39 AM] |

Running one CPU at 50% CPU time like you tried might be the answer, at least for powerful laptops. That seemed to work for me.
I don't think it's possible to run WCG and not generate some heat on a laptop. But reading your post got me to try putting it back on my main laptop that I use for work. I had tried running Rosetta@home on it but gave up because I was constantly fussing with number of cores and %CPU. On my 2019 Dell XPS 15" I'm now running 8.3% CPUs for one logical processor and only 50% CPU time. It has an Intel Core I79750H with six cores 12 logical, tons of power, but runs really hot when the cores are busy. This low setting doesn't bother me. The laptop is warmer, and the fan is running very low, but not noticeable over the music I have playing. Anything more gets the fan going noticeably and blowing warm air on my fingers. Yeah it vents thru the keyboard. So I think people will have to experiment, and it will depend on how they use the laptop and how the laptop handles heat. Some lower power CPUs might not generate the kind of heat my Dell XPS or your MacBook pros can put out, so more cores or more time could be used. I have a couple of old laptops I've converted to Linux and running WCG. Both have dual cores and I run them 100%. They run hot and the fans are noisy, so they're banished to the garage. I've also got an Android RCA tablet with 4 cores that I run 100% all cores and it runs cool, but takes a long time to process anything, so I know the processor is pretty weak. So a low end CPU in a laptop might be able to run more cores and/or more CPU time and stay cool. |

it depends on the laptop, the CPU and the efficiency of the cooling system. There is no one-size fits all approach, although the recommendation to only run one core to test and increasing by one core each time to find the optimal settings for you, certainly could be as close as we can get.

When I ran Boinc on a laptop I used a free program called TThrottle found here https://efmer.com/ . It allows you to set a maximum allowable CPu temperature, among other things. It works much better than the Boinc Manager settings.
