A target temp of 75 seems ideal.... but is 80 safe? What about 85? (specifically amd rx 400/500 series gpus ref and nonref)

75 seems good for rx series or somthing below, for me personaly 60c is my alarm when i reach that just try to increase the ventilation with everything i got to keep it below 60 , but my maximum temp is set to 75c , 80,85 seems a bit high for me some other ppl run thier cards more than that even 90 , so i think 75 is a good average so you can try to keep it below that. |

Ideally they should be under 80 but over 80 is also safe. I have a few of them at 80 and some ad 86. Works good for months |

That is the ideal maximum temp for a GPU to work like it should. The golden rule is the lower the temperature , the higher the life of a video card. I am mining with Nvidia and with fan up to 85% my maximum temperature never exceeds 74 degree celsius, but usually it mines Zcash within 69-72 degree celsius.
Old version of Nvidias have run for a lot of time with temps above 90 so I guess I can say 75 degree celsius is a pretty safe max temperature.

I agree keep it at 74. Or lower. And they can do 80-84 in a pinch |

Depends on how long do you want your cards to last.
if you want to resell them as new in two years, in perfect conditions, never above 60C and fan never above 60% PWM
but it is safe as long as you don't go above 70C, although using them at 70C for a long time will slowly damage the VRMs and the card probably won't survive for 2 years.
OTOH if you need to have fans at 100% PWM to keep the card at 60C the card would be fine, but the fans would be dead in months, so, you need to add fans and lower power of the card , soy you can have lower temperature and fans below 60% PWM.

Maybe I would think the fans would fail one year or 15 months |

by default since 290 days, amd default shutdown temp is at or around 94 deg C is i'm not mistaken but that does not mean to push it to the max, back in those days on the 290s even till now i'm still running them till now over 4 years ! 80 DEG C is ok. the lower the better but if you look at default & they stock limits or design is around 75deg C or so. i'd say 75 should be ok, best below 80C for longevity 85 deg C WARNING !

If we assume I don't care for how long they will work (they all have warranty of 3 years), what's the max ambient temperature in which they should be working? My cards are in a metal "house" directly under the sun and it gets to over 50 inside when the sun is strong. Then cards go to over 90 with 100% fans and extra (house) fans blowing inside to rotate the air... but that doesn't seem to help a lot...

Curious to ask, because I live in a place with above 80 or even 90% humidity at times, does "wet" air effect the reasonable amount of heat PCs can take or even the fan efficiency? I always suspected that my computers didn't last as long in non-air conditioned (still cool, but just much more humid) rooms.

I usually run my R9 390 below 75 degree. |

I have read in this forum that some ppl are running thier cards at 90c for years with no problems but that do not mean it's normal you are risking too much with your cards , also this 100% fans are going to die fast , i think you should find a better hosting place than that , temp shouldn't reach that much. |

Humidity is definitely an issue if it is "wet" enough. Luckily, the heat from the components of the GPU will evaporate the humidity quickly. I know a user a while back warrantied his EVGA PSU and complained on the forums that their warranty sucked because they denied his request. A member of EVGA actually ended up posting pics of his PSU and how they found rust on a bunch of his circuits. While the hotter running parts may be less susceptible to rusting, a lot of other components don't have that protection (MOBO, RAM, HDD, PSU, etc.) |

My personal goal is 70c and 60% fan speed. Anything lower then that is just icing on the cake for me. I don't worry too much if the temperature gets towards 80C at it's peak, but with undervolting that's not been an issue anyways. I live in a Northern, cooler climate, so the ambient temperature is definitely helping me out.

It depends, I got one EVGA 1070 FTW dead (smell of burning) after a few months at 72C~73C, while the other EVGA1070 SC is still alive. Although it's known old EVGA 10 series cards have overheating issue.

So then it's just rusting or moisture damage at any rate, rather than a heat threshold issue? I never did do post mortems on the computers that gave out - they were mostly built from spare parts anyway, and I always just put it down to hot, humid conditions of a cramped room steaming in the sun all year long. I tried googling a little bit, but it appears computer parts are meant to operate at up to 80+% humidity anyway. Then again, maybe they never really tested these computers in the conditions I used them in! |

With almost any silicon, lower temperature leads to powerful power consumption which leads to lower heat, that is why the try to keep mine around 65.

Maybe I would think the fans would fail one year or 15 months Thats a good thing if your warranty covers it. You get a new shiny gpu, maybe even a next-gen one. My 970 has one year warranty left and it runs with fans set at maximum. They are sleeve bearing type so they will not last long and I will get a 1070 when I RMA it. |

i sit on 60% and 60-70 degree no more, with recent gpu it's better to stay at lower temp, because they have lower nm technology, 14 instead of 28, and they are more fragile to high temperature like 80+, it's also better to add additional fan to not run the gpu fan at 80%+ and risking a damage
