I'll get the log when home.
Sure it happens three time playng that damn HDR HEVC 10bit demo that is only one minute long!!!  Encoding an x264 for eight hours did not shut down the PC. It happened some other times, though, randomly AFAIR.

Testing a brief encoding (AVC), and after almost an hour, temp never raised more than 77°C, and was mostly around 62-65...
I guess a GTX 1050 Ti should solve any HEVC decoding (and encoding as well) - it must have no problems decoding UHD 10bit, I think! Found some useful info here: https://forums.geforce.com/default/topic...-a-h-265-/ Quote:Feature Set D

Hmm, sounds like it might be some software configuration issue after all. Maybe some driver problem?
Yeah, the decoding will work way faster with a GPU that has an NVDEC that supports it. With that said, it won't help with encoding, as good encoders are all CPU-based. Yes, it can in fact encode, but the quality isn't comparable to an x264/x265 encode.

Sure thing, but, if I would change my GPU card, better to get one with also hardware encoding - who knows...
 Last thing: I was browsing my own thread about this very PC here https://fanrestore.com/thread-1312.html ![[Image: IMG_20170216_225246.jpg]](https://s22.postimg.cc/qqd13step/IMG_20170216_225246.jpg) when I've noted that now the light of the Enermax logo on the cooler is now very dim, and the surrounding "lines" are swiched off... this should be a sign of... "something", I guess! EDIT: from https://www.enermaxeu.com/it/service/faq Quote:CPU Cooler: Your CPU cooler fan turns off or LEDs are dimmed This must be the cause of dim LEDs, but I guess if it could be involved in the overheating, too - like, cooling does not cool enough...

Also, tested another UHD HDR HEVC 10bit demo, 59.94fps; in a minute, temperature raised from 32°C (idle) to 89°C!
stopped it, because I felt at 90°C PC could shut down... so, definitely, I need a better GPU to see HEVC UHD 10bit files - do note that HEVC UHD 8bit SDR files are played at a normal temp of less than 40°C, dunno if because "only" 8bit, SDR, or both.

89C on a water cooled setup is absolutely not normal. I have a $20 air cooler, CPU overclocked by like 700 MHz and during torture testing it maxes out at like 70C IIRC. Make sure you've got the cooler connected properly, like that site says.

Damn, that's definitely very hot yeah.
What makes it weird is that it doesn't happen during encoding. For shits and giggles, did you measure your CPU % usage during both encoding and trying to play back HEVC? Are they similar or are there some notable differences? Regarding the cooler lights: CPU fans are automatically regulated depending on how much cooling is required. The old connectors do this by changing the voltage of the fan, which is what that article is referring to. In other words, if your CPU is relatively idle, the lights will be dimmed because there is less cooling going on. I would check out how it looks under load, whether it lights up more. If it doesn't, maybe the CPU fan connector has become slightly dislodged or something like that. You could just pull the connector out (when the PC is turned off, obviously) and put it back in. Also, maybe check various other temperature sensors, like chipset etc., to see if that plays into it somehow, particularly since it doesn't seem to happen during encoding.

Got the cooler connector deconnected and connected again - tried various connectors - but nothing changed... the (tiny) manual says to eventually change connector (from 3pin to 4pin) using an adaptor, but I have not it.
Well, CPU usage is at 100% with both HEVC 10bit and AVC encoding... and LED remains dim, during both. What I ask myself is, why now? Maybe because there are SEVEN hard disks connected, and PSU can't give enough power to the cooler? Should I do some tests like, deconnect all the HDDs but the OS one, and see if LED stays dim and/or temp will not raise up? (OT: temp raises up, or temp rises up?)

What kind of power supply do you have in terms of wattage? Personally I think the fan would be the last thing to suffer from a problematic power supply, but you can check of course.

Check my system here: https://fanrestore.com/thread-1312.html I tried to run Cinegy Cinescore... it didn't end, because system shut down at 100°C! Changed BIOS setting to "power saving", rerun, and it top at 78°C - not low, but it is a quite stressful test. Noted that with previous "powerful" mode, CPU tops at 4000MHz and something (that is over its 3900MHz turbo max speed), while in power saving mode it tops at 3898MHz... so, why "pay" less than a mere 3% speed increase with such high temp? Yet, HEVC UHD still raises up temp well over 80°C... I'm half convinced to buy an over-the-top used PC, and sell mine! |
