The correct settings everyone else is using with this card are as follows:

Power limit : 75% 230 watt
Core clock : -200
Memory clock : +1200 max but even +1000 works ok just a few Mhsh less should be 95-96 Mhsh

These are windows settings,for Linux are the same just make sure you double the memory clock as in Linux that works differently.You should have a memory temp of 95 max by these settings.Just don't leave the card at the default settings as running 108 degree for an extended amount of time will make sure your card life span is less than what you expect.

Here is my setting, it is easily reach 103+ Mhs, mem temperature is 100C, fan speed 75%

Everyone is saying to me 100c is not safe for 24x7 mining
Am at 95c 100% fan and really worried
Ordered a few pads they should arrive soon
Gigabyte (since ever) is trash if u read newegg reviews on their liquid cooled cards even those got crappy pads and do thermal throttle, best IMO are Zotac and EVGA.

here are my settings overclocking my FHR 3080, however the fan speed is usually at  90-100%, is that ok for the fan on the long run ?

is it ok to keep fan on auto for 24x7 mining ?

http://grabilla.com/0bb1c-efa0c082-36cf-4b04-8dab-19f42d3bb499.png

also is it ok to maintain 108c for memory temp to mine 24x7 or what temp to maintain for 24x7 mining ?...

btw i finally figured it out
i had some of the old thermal pads still used for some of the memory modules because i ran out of pads, ordered more pads (certainly one pad sheet is not enough) and now have ALL memory modules covered both FRONT AND BACK, i saw temps drop down to 76c on memory modules and couldnt believe my eyes for quite sometime till i was finally convinced those are real results ! so if u r still seeing temps at 90+c then you should know you didnt replace the pads correctly, i even used 2mm+1mm for BACK thermal pads (ignore that nonsense saying DO NOT do it and air will get trapped BS) as you can see i did that and used a premium thermal pads (thermal right) and i couldnt be more happy with my temps !!!!!!! 76c down from 106c !!!!!!

plz do this with caution it took me almost 45minutes for this job and dont rush it and avoid electrostatics by continuously touching a metal thing next to u to periodically remove any electrostatics from your body, or wear a electrostatic wrist in your hand to avoid bricking your card and place your card on a NON CONDUCTIVE matt or something...

i can confirm for my gigabyte aorus master 3080 i needed 2mm front and 3mm back nothing more nothing less !!..... and now am getting 80 c temp @ 80% fan only while overclocked to 1300 MHz and 63% power limit @ 100mhs for ETH !!!

Nice follow up.  Good work with the pads.

I put pads, heatsink and fan on the back and it dropped the temps by 10c

100% fan is never good on any gpu, less 85% for green, 86% to 94% for orange and more than 95% for red, anything after that is dangerous territory, yeah could always replace the fan, memory on the other side could be less than 85c for green and 85c to 95 to orange and more than 95 for red, core temperature, less than 70c for green, 71c to 75c for orange and more than 76c for red, keep those values in check for 24/7 and you should be good.

After I have changed the thermal pads on my 2 3080 I have been mining eth with them when I'm not using them for deep learning or gaming, right now on eth memory temperature is 76c, fan at 85%,before thermal pads was, memory temperature 110c and 100% fan when testing eth, i was not crazy to mine eth or use memory intensive programs with such temperatures and I took the time to change thermal pads, must never change thermal pads fast, 3 months at least then replace thermal pads.
