Subj : Overheating CPUs To : Ky Moffet From : Barry Martin Date : Wed Dec 30 2020 13:31:00 Hi Ky! > KM> Wait, it IS the weekend... where's the party? DON'T TELL MY > KM> PCS!!! > Even they are doing it virtually! That's the real reason your Internet > connection is so slow: all the computers' Zoom, Skype, etc. KM> Ha... first attempt at Zoom for the family Xmas (being a bit KM> scattered around). My upstream is not up to it! And then a cousin KM> called my mom so we had her "Facetime" secondhand by way of my KM> mom's Zoom. One step up from tin cans and string. I haven't even attempted to Zoom, Skype, etc., as no one to video chat with. Probbaly just as well. > KM> And sometimes become scarce and expensive, like LGA1366 > KM> heatsinks. > Some people sink their money into gold, others heatsinks! KM> Is THAT my problem.... Well, one of 'em! > KM> Mighta mentioned, someone lately gift me several nice 3rd gen. i5 > KM> and i7 laptops that were discarded by the school district... > I'd half-bet if they put the school logo sticker over the manufacturer's > processor one three-quarters of the students wouldn't have known they > were the older generation! ...'Course then there's the kids who know > how to get into the specifications. KM> Oh, no, these were from admin and IT!! ....where sadly, I have KM> reliable reports indicating they know even less. I could see the admin people but the IT people are supposed to have been trained in more than just the basic stuff. "How to turn on a computer" doesn't mean sending it flowers and candy! > > Not really: he has an older Ham license so AFAIK back then > > they had to know some electronics theory. I do know there are some > > liquid-cooled units out there -- friend in Nevada had one leak. > KM> Oy. Well, Nevada. If it don't cook, it gets corroded... > Nah: that's Utah and the Great Salt Lake! KM> Ha, no, the southwestern deserts are all extremely alkali, and KM> the very dirt is corrosive. My yard down in the SoCal desert KM> actually tested off the scale... person doing it thought the test KM> unit was broken, but nope, it's actually that alkali. Dissolve KM> dirt in morning dew and it eats everything it touches. Hadn't heard of that but makes sense. ...So there you had to worry about acid rain and alkaline yard! > Yup: if can't cool one way cool it another. I'm thinking a big fan > could rotate slower and push the same amount of air as a small fan > rtating faster but with less air flow noise. Another factor might be KM> Probably so, but first one must have the big fan, and a place to KM> put it! True. Stuff doesn't work if doesn't have a place to be. KM> Enermax PSUs for many years had both an intake and exhaust fan, KM> which no doubt helps explain their longevity. I've only had one KM> die, and it did 17 years service at my house and who knows how KM> long before that (dated 1998, IIRC). Thinking in general it's too bad there isn't some sort of data communication between the PSU and the motherboard to send fan rotational speed and internal temperature so could be monitored. Probably just temperature would be sufficient: getting hot probably means the fan is having problems. > > Why am I thinking 'Karma Surta'?!! > KM> Wait, WHAT ARE THOSE PCs UP TO???!! > Now where do you think those little 'portable' computers came from?! KM> Ah. My basement is explained. Now you can call it "The Nursery". > KM> Square peg, square hole? Check!! > As long as it's approved by the manufacturer! KM> Went out of business!! Naa: just taken over by another who figured out to use circular holes and pegs to cut assembly time because no longer had to line up the squares! ¯ BarryMartin3@ ® ¯ @MyMetronet.NET ® ....
