To temp limit or not and what temp?

[thesavoyard]

I read on this forum that the magic number seems to be 70c. If you stay above it there's a good chance your cards will die. If you stay below it, running them for four years is a reasonable expectation. To the pro miners, what do you think? Also, would a solid product like the Nvidia GTX 1070 need a limit that low? I'm honestly losing a lot of Sols by staying at 70. I could be doing nearly 10% more removing the cap.

I dont have any 1070 or 1080 nvidia cards for mining , but i have plenty of rx 480/8gb AMD card for mining from msi / gigabyte / xfx / SAPPHIRE . I found the "sweet" temp for those cards is 75 celsius , on that temp all my rigs stable . I tried 80 , 85 c but on that temp i got random rig reboots , opec cl errors , miner program restarts ...

Pascal seems to be more temp sensitive

People may be running them with a 70c temp limit but has anybody successfully ran a Pascal card for 4 years of mining like that? Answer is no because we are not at 4 years.

If I am mining something that is all core clock dominant where I can underclock the memory I will put the temp limit at 65 but otherwise I set it at 60.

The cards are supposed to work in 70's but mining is a 24/7 workload and NVidia doesn't have a rep for longevity like AMD does. run 60c if you want to get a good life out of them. Avoid over voltage also because I got a card I kept below 50c in a freezing room and I smelt burning after 2 days and there was coil whine that stopped once I reduced the OV

I keep the power limit at 85% but I'd like to up the Temp. Any more opinions on the longevity if I set it to 75c? You cannot change the core voltage of Pascal without creating a power curve, you set only a power limit. I'll have to disagree on the longevity of Nvidia, after 25 years of PC gaming it seems the budget friendly but power hungry ATI cards have always had a higher failure rate.

I honestly wouldn't worry that much about it, but at the same time don't go crazy, I have several 1070s running since launch day in the mid 70s without any issues. I would agree though that you want to keep them at a lowered power limit. As for longevity and nvidia, well I still have a gtx 480 that I used for folding @ home for years before I knew anything about temp limits or bitcoin and it still works for what its worth...
