Dear All, I upgraded my PC to i7-9700k and rtx 2070. I'm just wondering that what's the safe temperature for running boinc on a long term basis (5 years maybe, 10 years ideally). 7 days 24 hours My current temperatures are 80c for CPU and 70c for GPU. Cheers |

Sounds OK for both. Ideally achieve as low as possible without extraordinary measures. For every degree of temp reduced, the life expectancy increases exponentially for modern electronic circuits. Mechanical parts like fans will fail first. |

Mechanical parts like fans will fail first. thank you Keith. It's a clevo laptop, if the fans fail first, I think I don't have to worry about the other parts. I think the life span of the fans is less than five years if they're running 24/7. |

For laptops, your problem will be clock throttling because of temperature with reduced performance. Laptops were never meant for 24/7 distributed computing. They were designed for infrequent browsing, reading mail, watching video and occasional business work loads. Laptop thermal solutions are incapable of removing the constant generation of heat that BOINC crunching produces. If you hew to the original intent of BOINC, that is use of spare cpu cycles when the screen saver is on, it will be fine. |

Laptop thermal solutions are incapable of removing the constant generation of heat that BOINC crunching produces. Or if you are happy to use just two out of four cores for example. On my laptop fan doesn't come on in current temperature with only 2 cores. Mind you, it is quieter now with all four than it was in summer with just two. Then for fan to not run I needed to go down to one core. |

The lower the better. However, I run mine between 50C and 65C, depending on the environment (they're outside). Occasionally it dips below 50C, or above 75C. You don't want to run it at 80C prolonged. THe silicon can withstand up to 100-120C, but the capacitors don't last at those temperatures (they're on the board under the heat sink). For that reason, you always run fans at 100% when folding/crunching. |

Laptop thermal solutions are incapable of removing the constant generation of heat that BOINC crunching produces. Desktops, and GPUs in minor ways too. They throttle the speed depending on temperature; which is why you will want to run them as cool as possible. |

I do not agree, I am runing 9 pcs and try to keep temperaturs bellow 65c. The worst one is my amd a10 7700k cpu. (I think it is a liding problem with the chip) I use msi afterburner or precison xoc to control fan speeds, voltages, and frequences. Also bios setings for cpu and case fans. There are many programs that help, like core temp. Remember, the hoter the temp, the sooner the smokeshow. JP |
