Hi, I've been performing tasks for World Community Grid in the winter/spring period and my cpu temps were like never higher than 65 degrees when running 3 tasks simultaneously, now if I try to run 3 tasks simultaneously my cpu gets much hotter, it sometimes even reaches 85 degrees and averages something between 75-80 degrees, I would like to know if the change is due to the change in room temperature (in this period of the year, summer, the average temperature for the day in my country is like 30 degree, back in winter it was much lower) and if it is safe for my cpu to run at these temps. I use a laptop and my cpu is a i5-7300HQ.
Sorry for my ignorance and my terrible English. |

I would suggest picking up a can of compressed air and blow out the heatsink on the laptop. Dust buildup will quickly add temps to a computer, especially a laptop. Can you hear your laptop fan spinning faster as temps rise? If not, there may be an issue with the cpu fan.
Also if you are able to, try using a laptop cooling pad. It helps lower temperatures by two things: it raises the laptop off the table for better ventilation, and they have active cooling fans that blow cool air up onto the bottom of the laptop where the intake vents are. Also, make sure the laptop has plenty of room behind it for hot air exhaust. The rear of the laptop is typically where the exhaust vents. There is also a program called tthrottle which you can use to keep your laptop from overheating. |

Also, the Tjunction on that processor is rated up to 100C, so even at 85C you are in stable operating temps. It definitely is a high temp, and may reduce the life of the processor over time. So I would try to lower it if possible. Ambient temps can have an effect on the cooling ability, but you should not see a 20C difference on the laptop just with change of seasons.

I hope it all works out for you. Let us know if you are able to drop temps down.

Depends on the construction of your laptop, but I find blowing a fan on the keyboard is more effective than a laptop cooler. I think laptop coolers exist because they have to be designed that way. I use a USB Arctic Fan and blow directly near the exhaust area of the laptop.
It is amazing what dropping a few percentage did for my MacBook Pro. I went from 100% CPU, 50% of the time... going around 60°C with 3k rpm. I lowered to 100% CPU 47% of the time, and it is 50°. I use smcFanControl on the MacBook Pro so I can adjust fan RPM. Long-term though, laptops that have terrible cooling properties (see latest MacBook Pro i9 for example) and you're better off using desktop. I can run my Dell i5 at 100% 95% and barely reach 75°C. And that's just using passive cooling and a massive stock heatsink Dell uses. |

What is the manufacturer of your laptop by the way?

What is the manufacturer of your laptop by the way? Acer I had an old acer from around 2008. It had a large panel on the bottom of the laptop that allowed access to the hard drive, ram, processor, and processor fan. It was really nice for cleaning/upgrading. I took that panel off and put it on a laptop cooler when using it as a dedicated cruncher, and it kept much cooler. I no longer use it though, still have it around as a paperweight. |
