So an average temp of about 85° is more than otpimal for the GDDR6X gpus?
That's better!

Yes, 85° is a good memory temperature for GDDR6X cards. 70° or lower is a good core temperature.

But the downwards temperature is not the core temperature, but the junction one or the memory one, i read from other sources on the web.
The core temperature is good, that is 45°.
Are you sure that also the second temperature showed downwards, must be kept below 70°?
I read that the GDDR6X vram gpus works at higher temperatures and values between 80-85 should be acceptable for mining 24/7.
In gaming the GDDR6X vram rises to 100° about, but that is not 24/7 so can be good.
Can someone who mines with these gpus, give me a confirmation?
Thanks.
You are absolutely correct that the reported 'core temperature' isn't the whole picture. The VRAM can get much hotter than that. The worst I've seen is my XFX R9 290 where the core was 80° but the VRAM was 132°. This is especially true on the RTX 3000 GDDR6X series. But thankfully, VRAM temp can now be reported in Linux.

On average for my RTX 3080's/3080 Ti, the memory was 30-40° hotter than the core. The card will throttle if temp goes > 110°, but ideally, you should stay under 100°.

Other than that, I've used hundreds of video cards. As long as they don't use GDDR6X, all you need to worry about is the core temperature. Stay under 70 degrees, and if you can't, reduce power usage so you stay < 80. It's always better to increase fan speed; fans are cheap to replace.

85 degrees is too high. It will reduce the lifespan of your video cards by 1-2 years.

I recommend staying below 70 degrees. There will be no benefit below that. The most important factor is that you reduce heating/cooling cycles, which destroys the silicon the fastest.

Hi everybody,
I have some gpus in my HiveOs rig, showing two values for any gpu: the value located upwards is about 45°, while the one located downwards is about 85°.
This happens only for my 3 3070Ti and for my 2 6800 XT gpus.
The higher value i think is the junction temperature(or memory temp?), right?
Do you think is it safe to mine 24/7 at so high degrees?
Thanks!
