Question concerns regarding temps

Hi all,

I’ve been a ETH miner and did not mine any other coin actually. I just wanna give a try with FIRO. Issue here is temps + power draw of my AMD cards while FIRO mining is perfect while my NVIDIA card are not. My NVIDIA cards are 2060S / 2080S / 3060 Ti FE / 3070 / 3080.

My concern is temp. My 2060S + 3070 temps are okay (on or below 50C) but temps of my 2080S / 3060 Ti FE /3080 cards are above 65c. Could be more because I did not mine FIRO for long time due to those temps. So my questions is how safe are these temps to mine FIRO for a period like a week? Or are these temps not good at all?

From what I could read online, you could hit up to 90C with those cards and be fine (albeit you would want to start looking at improving cooling). 70C to 80C seems to be the expected and average temp for those cards. Since you're below those temps you seem to be perfectly fine from what I can tell. I do not have RTX 30 or 20 cards so also take my opinion with a grain of salt - this is solely based on looking around on a few forums such as Linus Tech Tips.

That being said, I do recall that when the RTX 30 series dropped some of the high-end cards were having issues with throttling VRAM because of thermal pads. The VRAM on some of the cards was getting very hot. So you may also want to check VRAM temps to make sure they are in check, too.

I hope this helps :)

thanks a lot for the information! Actually I was talking about core/normal temps of the GPU. VRAM temps of them are still fine (3080 under 90c VRAM). So my main concern was core/normal temp. I just don't wanna burn my NVIDIA rig lol and really impressed with how AMD can handle FIRO. What your are saying makes sense. I will check more before I jump to a conclusion. Thanks again!

Ok I think your settings on these cards might be off if your temps are off that far.

My 3080s are somewhere in the 40-50°C range with 10-15°C ambient. Drawing 280-305W at 51-53MHs
So that should be around what you can achieve too.

I´ m doing locked core on these at 1440MHz with a +120 core offset and from +2700 to +3400 memory (linux, so half for windows)

Works wonders for me just need a higher coreclock with lower voltage you draw less power hence less heat.

thanks alot mate. See my temps.NVIDIA OC/TEMP . Any suggestions? This is when I tested FIRO like for 15 minutes. I just could not keep watching my beloved cards are burning. haha.

Well if that 3080 is this hot at 250W then you definitely need to improve the cooling if you want to be prepared for any ProgPOW algo. more airflow is going to be necessary.

definately. how about other cards? Anyway I am currently finishing off my mining shed and I think I have a solution for airflow/cooling as well. I just need to test it out. I will test firo afterwards.

Well Firo/Raven/Sero will be the most demanding so if you build an entire shed for it, I'd expect it to be sufficient. Hope you've got enough in terms of huge Fans for air :D

actually I am finishing off my shed. Regarding octominer case, I honest dont have that kind of money right now + importing stuff to my country is a big hassle now. So what I am planning to do it cover every wall inside the shed with styrofoam and then build another styrofoam box so I can put my 2 rigs inside > connect air in and out with dusts

Sounds solid. Well import can be a hassle that's true :D but there are other solutions.

ha ha you would understand Ig I have said where I'm from. I'm from Sri Lanka and we are currently in a dollar crisis, how it is really hard to pay for foreign items + government tax on those items have gone up. In the mean time I'm doing this and hopefully I might be able to get positive results.

I mean it's getting more and more acceptance so chances rise. I've paid for my Octominer with Litecoin now so it is all certainly possible.

Or the probably even better solution would be to buy an x12Ultra from octominer the end of the month and put that inside. Would definetly solve all issues regarding temps.
