Crunching on my laptop, and Aida64 showed the core temp 75C.
I planned to crunch 24/7, will it shorten my device lifetime? Shall I purchase a cooling device, or I just shouldn't left my laptop 24/7 running? I'm using a i7-6500U laptop |

The most important thing on a laptop as far as I am aware is to keep the temperature under control. Make sure your fans are good and your vents are clean. Then monitor it for while to see how the machine handles its heat.

75C seems rather hot to me, but that processor tjunc is rated at 100C according to Intel . It is listed as a 2C/4T processor, so if you wanted to run 24/7 and drop the heat a bit you could try running 50% processor usage or a program called tthrottle is rumored to work quite well.
If you would like to run the device 24/7 at 100% then I would recommend a good laptop cooler. If the laptop is going to be stationary and used like a desktop, you could look at the bottom of the laptop and see if there are any access panels that can be removed. Some have panels to access the hard drive, RAM, or more. Removing these panels may add for more airflow from the laptop cooler fans. |

I have a similar program called BES, used it daily before I saw it on the recommend list on BOINC website. I'll try reducing my VM's core number, too. If you would like to run the device 24/7 at 100% then I would recommend a good laptop cooler. Just ordered a cheap laptop cooler online, will try that on when it arrived.

No, I take it to the lab sometimes, but I got my HDD separated, and that might help (though that's not my first purpose). This laptop came with a preinstalled ssd, sure that I'm not going to crunch using that. So I installed WTG on one of my HDD and boot my computer with it to prevent writing to my ssd too much. Thanks.

I wouldn't worry too much about the amount of writing WCG would do to your SSD, assuming the brand quality is decent and there is spare space on the disc to move stuff around. You do have backups, don't you? The first lesson came quickly. All of the drives surpassed their official endurance specifications by writing hundreds of terabytes without issue. Delivering on the manufacturer-guaranteed write tolerance wouldn't normally be cause for celebration, but the scale makes this achievement important. Most PC users, myself included, write no more than a few terabytes per year. Even 100TB is far more endurance than the typical consumer needs. https://techreport.com/review/27909/the-ssd-e...xperiment-theyre-all-dead The only small caveat about that 2015 test is that they were all probably MLC drives with higher write capability per cell than current TLC or QLC models. |

You do have backups, don't you? Yes, compared to rosetta@home(which, with no WUs on my computer, occupied 900M disk space) or what, wcg saves a lot of disk space. Yes, my ssd is an OEM product of Micron, and I'm sure that's more that just "decent". And, yes I do have several backups.  But, no, I only have one ssd altogether, and I'm only a college student with just a few money, and I'm going to treat it nice.  https://techreport.com/review/27909/the-ssd-e...xperiment-theyre-all-dead I've read this report several years ago... Seems such experiment is REALLY popular! ...they were all probably MLC drives... And, nope, according to the report, there IS one TLC candidate: ...when the Samsung 840 Series started logging reallocated sectors. As the only TLC candidate in the bunch, this drive was expected to show the first cracks.... Though that seems very expensive to me ,too.

Also remember in BOINC that you can change the computing preferences to checkpoint at most every x seconds. I think default is 60 seconds, and I don't know what the max number you could put in there. But if you add a zero to that, the work units would only checkpoint max every 10 minutes.

I run at 1200s minimum checkpoint time, also ran at 3600s some time ago. No problems. Can only recommend that for 24/7 crunchers

Hueri (hero),
----------------------------------------Your laptop is not running excessively warm/hot. But, if you have concerns, there are inexpensive fan platforms made strictly just for laptops. Also, the disk activity of this project is not intense enough to worry about ANY type of disk drive problems. Just make your default save to disk about 5 minutes. I have run 5 different laptops on this project - and only one of them ever needed the extra fan/cooling support. Thank you for coming here to help all those that truly need our help. Just an added note. It is not the heat that normally kills a computer. It is the shut down and turn on that does. A computer has a longer life if it is kept running. The temperature CHANGES are your computer's worst enemy. James* [Edit 1 times, last edit by James Lee72 at Jan 13, 2019 11:06:10 PM] |
