At the moment in the piping hot weather in Scotland,? 25°c to 30°c is piping hot? I'd hate to be there when it's cold. Min 21° to 31° max here which is only a few degrees above average for this time of year. Grant Darwin NT |

At the moment in the piping hot weather in Scotland,? I have a conservatory, which means 20C outside makes 30C inside. Min 21° to 31° max here which is only a few degrees above average for this time of year. I'm uncomfortable above 25C when sat still in only shorts. More clothes or any moving around and I need it cooler. How on earth do you put up with 31C? That's only 6C under your body temperature, do you sweat continuously? How do your computers stay cool? I find things like graphics cards overheat if the room gets to about 28C. |

How do your computers stay cool? I find things like graphics cards overheat if the room gets to about 28C.When i'm home the aircon is on, which keeps the temperature inside down to 27°. When i'm not home the temperature inside is generally 35° to 38°c (humidity can be as high as mid 90s). Water cooled CPU, large good airflow case with several large fans keeps the computer going even in those temperatures, And the video cards i buy always have 3 fans & large heatsinks.

I have cards with 3 fans, they still detest high temps. At 25C, they run at 70C with full fan speed. I don't like a chip over 70C, despite the manufacturer setting the default fan speed to maintain 80C. Over 70C smells bad. At your 38C, my cards would be 83C, which is way too hot. And you must have powerful aircon to be able to cool it quickly when you get home. It takes mine 1 hour to change the house by 4C in either direction. |

I've read that video cards that blow the heated air outside the case of the computer can be better in controlling GPU temperature than those with 3 fans that don't blow it out of the case. The building I'm in has 5 powerful air conditioners, not under my control. My computer room also has a window air conditioner, under my control. I keep that one turned on for the full year, using a setting that keeps its fan running at all times but only cools when needed. |

I've read that video cards that blow the heated air outside the case of the computer can be better in controlling GPU temperature than those with 3 fans that don't blow it out of the case. I used to prefer those, but they tend to have only a single fan, so don't cool that effectively. Although they don't heat the rest of the computer up, but that's not important if you have decent case fans, or in my case (the other kind of case!) I have them sat in the open on a bookshelf to run Boinc. Only 1 is inside a case, the one in my living room that I use as my main computer. Everything else is in the garage to keep the noise away from me! The garage gets rather hot as a result, so I leave the windows open. I've recently installed some wire mesh to prevent my neighbour's cat from entering and tampering with the computer equipment! The building I'm in has 5 powerful air conditioners, not under my control. My computer room also has a window air conditioner, under my control. I keep that one turned on for the full year, using a setting that keeps its fan running at all times but only cools when needed. Why keep the fan running if it's not needed to cool the room? The unit I just bought does that for no reason. When the room has reached temperature, turn off and be quiet! I've since modified it to make it more sensible. |

Erich -- A hat-tip to you (and, to Robert, for trying to help/enlighten me). With your suggestion, have now uploaded all the outstanding wu's, with a dozen, downloaded. As in my last previous entry, I still feel that the Boinc software gents need to update Boinc, ASAP, because of Baker Lab's importance. Yes, I'm griping, but -- as a retired hardware engineer (mini-computers, to date myself) -- I know how fast the gents in the corner office want Eco's/Rev's generated. Out the door. . . So, I still can get antsie, at times, when an important Boinc rev. is concerned. Again, hat-tips to you/us all. Let's get a vaccine! |

I'm more sensitive to CHANGES in noise than to steady unchanging noise. My computer room is also my bedroom. |

As in my last previous entry, I still feel that the Boinc software gents BOINC is now offering some new versions with an updated ca-bundle.crt - only for testing so far, but with plans to release the new versions if the tests don't uncover any new problems. Download BOINC client software https://boinc.berkeley.edu/download_all.php Email from the boinc_dev mailing list is not working yet, but the web version is working and so is email to the list. I used to be a hardware engineer also, with heavy use of mini-computers but not working to design them. I'm about to install one of the new test versions. |

[snip] I like the relief when a noise stops. And I cannot sleep with any noise whatsoever. I actually boarded up and very insulated my bedroom window so I cannot hear a dog barking, a car passing etc. |

Thanks for the update. I have installed it on my machines. |

My newer/faster computer which does NOTHING but Rosetta ran out of work for about a day with uploads/downloads pending. Somehow it was resolved without action on my part. My other computer which is shared between me and Rosetta still has uploads and downloads supposedly in flight. I got a notice suggesting to remove the project and re-add it with the corrected (HTTPS) URL. I removed it, but now attach fails. |

Install the new 7.16.7 version of BOINC, even though it is still marked as for testing, It includes a fix for this problem, and the only other change since 7.16.5 is the version number. https://boinc.berkeley.edu/download_all.php Scroll down if you also want the new Android version, also marked as for testing. |

Hmmmm, OK. Any idea why it recovered on the one without doing that? I finally connected the old computer to BOINCstatBAM!, but I couldn't re-attach the project through there, either. But here's where it gets really weird: I COULD then attach the project through BOINC Manager. BUT: Once again, things are just "downloading," never downloaded. Maybe I'll try 7.16.7 tomorrow. |

again, for the people who for some reason do not want to re-install BOINC yet: the file "ca-bundle.crt" contained in this link https://onedrive.live.com/?authkey=%21AAVyh7jontFKASg&id=B0BF9B80B38343C5%21665&cid=B0BF9B80B38343C5 can be used for replacing the existing file in the BOINC folder (usually in C:/Program files/BOINC). This is a very simple procedure, it's done within half a minute, and the BOINC manager does not even be closed when doing the file replacement. It worked well on all of my computers. |

My phone has not been updated (yet), and it can contact Rosetta, but not LHC. I assume a server end fix has also been implemented at Rosetta but not LHC. I finally connected the old computer to BOINCstatBAM!, but I couldn't re-attach the project through there, either. My Boincstats statistics have been out of date for a while, I assume they couldn't connect to Rosetta either. Their stats for Rosetta are now correct, but LHC is still out of date. I assume they haven't done an update at LHC or Boincstats. |

I could not install the Android one on my phone, it said "App not installed, the package appears to be corrupt". I had to uninstall the (newer) existing version first. It was running 7.16.5 already, so it was rejecting the downgrade, but not stating that! I wonder why they've given it a lower version number than a previous one? And it refuses to attach to LHC now (all other projects attached fine). I tried from the project list, and also manually entering the URL https://lhcathome.cern.ch/lhcathome/ I can get to LHC fine with my Windows 10 PC. My older phone (which did the upgrade ok as it had the ancient version) still has LHC in its project list, but when I try to update the project, it defers me for 24 hours. Something not quite right there. |

again, for the people who for some reason do not want to re-install BOINC yet: I wonder why Boinc didn't just include it in the Project files and force the download to every user instead of coming out with a whole new version? The Developers are smart enough to figure out where on our system the current file is and replace it, sure some systems are soooo locked down it wouldn't work but a clear error message would address that and give enough info to get it fixed. |

[snip] I could not install the Android one on my phone, it said "App not installed, the package appears to be corrupt". Are you sure the phone previously running 7.16.5 was running the Android operating system? If it was previously running 7.16.5, it had to be running some other operating system for which that version exists, and is therefore unable to install any software meant for Android. One possible exception - you might be involved in BOINC alpha testing, and therefore have access to versions so new I haven't read about them yet. However, if that were true, you would already know enough about BOINC that you wouldn't be asking me much of anything. As for LHC, I haven't participated in that project, so you'll need someone else to answer, |

Probably because they didn't think they needed the ability to do that, and therefore didn't give previous versions the capability to allow doing that. |
