What temperatures do you run your cards at? I keep mine in the low 70s and 60s if I can. Have people been noticing a higher death rate with certain temps, from experience, not theoretical.

86c for my 980ti 24/7 no errors due to that temp. Never had a card fail.

60-65°C for my previous gtx980 (MSI) and my current gtx1070 and 1080, also 24/7. The latter Palit GameRock/Jetstream Cards are 2,5 slots high and therefore have extremely good cooling just by sheer radiator mass. Fast, cool and silent, but a little bulky and therefore maybe not everyones cup of tea.

Mild downclocking by ~20MHz surprisingly reduces the temperature of the Palit (and also for the identical Gainward) by another 5-10°C right away. However that may be different with ASUS, Zotac, Gigabyte, EVGA or other products.

Normally the electronic components can withstand much higher temps (>250°C) in order to survive flow soldering, but only for a limited time. So my assumption is that at least the capacitors last longer at 24/7 temperatures less than 70°C. But you know, everything is possible and even a well cooled GPU can fail after one year only. There are little studies on the web with statistical significance, so we can only guess.

Try to keep mine at 75c or lower as from my experience this helps reduce errors, system crashes or bad data being created.

My Maxwell GTX 980 Ti GPUs, which use GPU Boost v2.0, ship with the "Temp Target" set at 83*C. And I've noticed that the drivers will start dropping GPU clocks, when temps get near that.

So, I create a custom fan curve, using MSI Afterburner, where maximum fans are attained before that point, at 80*C. As a result, when this PC is crunching, the GPU fans are quite loud, but the temps stay around 70-80*C, at full clocks, at all times.

Fun!

that's interesting to read. For how long have these cards been crunching?

I also have two 980ti (Palit Jetstream) in one of my PCs, crunching 24/7, and with the NVIDIA Inspector I set the temp limit to 63°C. Am I too cautious?

Thanks, Zoltan, for the thorough and informative technical explanations.

So I was not wrong by not overdoing it with the temperatures, and I'll keep them at this level.

Hello , I've been crunching occassionally with gigabyte geforce gtx-780. Would be nice to do it more but gpu-fans keep noise. How can I make the card silent (lower frequency or something)? I have ubuntu 16.04 , core2duo , driver is 340.101. (newer driver seems to cause computer start-up problems somehow). 'Nvidia x server settings' don't allow to adjust frequencies but is there a way to adjust that somehow?

Another way to set the coolbits option is to open a terminal session and enter the following command:

I have an EVGA 1080 FTW Hybrid. The waterblock keeps things COOL. Ambient room temp of up to 28-29C, I've never seen the GPU temp go above 51C. I have a 760 in the same box, it runs around 60-65C at the same time. Not worried about either, well within a good temp range for the cards.

The GP104 chips have a low TDP, 140-180 watts, and since they throw just as big of a cooler on them as the 250 watt cards, they definitely stay cool.

Currently running a EVGA GTX 1080 SC ACX 3.0. Previous card was EVGA 980Ti SC ACX 3.0. On GPUGrid, with both cards I rarely got much above 60C. The 1080 almost never goes above mid-50s. I do use a custom fan curve, but it never needs to go above 80% and usually runs about 60 - 70%. Part of that is due to having a very well ventilated case (Phanteks Enthoo Primo) and part of it is just due to the superior cooling ability of the ACX fans over the reference blower style.

Hello and Thank you all the coolbits-advisors. I somehow managed to get editable options to "Nvidia x-server settings" , obviously with a help of little luck. "Standing by" for further experiments. Thanks!

96°C (205°F) is pretty much.

It's a laptop (i7-4700MQ CPU @ 2.40GHz, 8GB RAM, GeForce GTX 765M (2048MB)).

A good example to demonstrate why *not* to crunch on a laptop.

Run time: 66,440.80 (18h 27m 20s)
CPU time: 21,693.78

True ... so if one really, really wants to crunch on a Notebook I would strongly recommend to run TThrottle at least in order to keep temperatures below 80°C.

Having said this, even that protecion mechanism is relatively slow and cannot fully avoid load and temp fluctuation on a mobile device at a somewhat critical level. As for me, I have stopped crunching on my laptop for that reason. Aside from the vacuum-cleaner-like background noise.

Edit: whoever owns that 96°C hot laptop ... didn't you observe burn marks on the table? ;-)

I would love to see HCF1 protein folding and interaction simulations to help my little boy... someday.

Crunching on a laptop, even if the gpu is somehow magically cool, kills the fans in a matter of weeks, at most a matter of months.

Hello folks , I think I got coolbits working , (gtx-780) , temperatures dropped down 5-6 degrees and fans got little more silent with underclocking that -105Mhz that the x-server setting page said to be minimum amount ,... but have anyone underclocked even more? Could it be harmfull to card to reduce the clock-frequency for example 300Mhz?

This is a new world record: 99°C, and it's *not* a laptop.

Probably passive cooled, and did I real that right? 1399mhz? That can't be stock.

I'm glad I switched away from EVGA Precision X, and to MSI Afterburner. Said GPUs are still happily crunching at custom fan curves, at full clocks, no problems, to this day... with MSI Afterburner.
