Radeon RX Vega 64 overheat problems causing rig crash

[Imelbi]

Hey guys, I bought 2 Radeon RX Vega 64. One of them works almost normal, with Temp around 80°C-86°C with fan on 48%. I tried setting vent speed manually in AMD settings which helped.
The other card had problems and I got it replaced, now the new one came and has overheat problems, even if I set vent to go higher and I set higest allowed temp to 80°C. Yet GPU stil causes problems and crashes.
The same GPU shows 8(i think so) red LED lights at power pins at top, I dont know what does that mean, the other one doesn't show the lights.

Anyone with same problems?

your vega are running at a very high temps
my six vega rig in which all gpus are running at 50 to 65 degree C
hbm memory will crash at the temps you are running your gpus
ramp fan speed to 4000 rpms

I ramped fan speed to maximum and i still get high temps, I added extra vent to cool them down.

Would you please send me you WattMan or afterburner settings?

maybe the problem can be you did not undervolt the cards much
which means that they consume a lot of power which is not needed and in turn convert it into heat
i will recommend checking reddit post vega definitive guide for mining
everything is available on that post and that should help to reduce temps
