I'm wondering what's the average fan speed some of you use?
I have some GPU's that are ok with 50%, but some need 70%. I've heard some people say 70% will kill your cards early, while others have said 70% has lasted them years. Anyone have experience?
Keep your cards below 70C, do this with --limittemp=70, that way all software quits
Have little 10cm fans in front of the cards, one per every two graphic cards, most rigs have a slot for fans
have a big fan 50 cm that blows cool air perpendicular below the cards to keep power-supply and cpu cool and bring cool air in below of GPU line-up.
Set the power 60%, say you have a gtx-1070, then the power is say 150W death, I run at 110Watts, and they run full clock at 59C, never come close to the temp-limit.
For 1060, run at 95 watt per "nvidia-settings -pl 95 -i x', where x is gpu number
Now to fan's "LEAVE THEM ALONE", default to AUTO, having the fans run at full just makes noise
The way you keep your gpus cool is with the little fans in front ( facing the connectors ), and the big fan on the end of rack blowing cool air below and over the top of the cards.
LEAVE the fan alone, all you do is burn out the fan motor on your GPU card running at 100% and then you have a DEAD-CARD.Little 12v fans with led lights costs $3 each, the 50cm big 110/220v fans cost $10, one per rig, and little fan 4 per rig, so cooling cost is $22 per rig.
It's important to keep the GPU cool for long-life, and to MINIMIZE the money you waste on POWER,
The little fan on the GPU card is designed for a solo card in a box, its NOT designed to be surrounded by 1/2 a dozen heaters.
