Miner 6x1080ti - one of the card is heating up

[ledsgo]

Hi Everyone,

I have a mining rig with 6 card GTX1080ti running Zcash on the latest version of EWBF Cuda.

Windows 10
Motherboard Z-270-A
PSU 2 x EVGA supernova 1000w

All my cards average 740 sol/s

I adjusted my fans so the temperature of my cards are below 65 degrees.

One of my card is getting much warmer than the other so I have to reduce the setting (lower power limit to 80%) and even then the card is getting close to 70 degrees.

Anyone had  this problem before and how did you solve it?

Thanks!

Is it socket or card specific?, could you move the switch the hot card with the place of another card and see if the card still gets hot or if the card now in the hot position gets hot.

Are all of your cards identical? (If not, some just might have better coolers than others. For example, in an open-air configuration, cards of the same GPU with blower-style coolers tend to run hotter than those with say, triple fan coolers, when at similar fan loads.)

If they are, it's probably just a location issue, as ms5 suggested it might be. Consider which general direction the fans are pushing hot air towards, and you might be able to explain why one card runs hotter.

That temperature is considered good enough and it will let your card live long enough to make you lots of Zcash in your case. Any card with temperature 70 degree celsius and below is considered a good temperature. In fact the miner shows in green every temperature below the 70 degree and in yellow from 70 degree and up.

If it is a location problem, you can just buy a miner cage in ebay or amazon for cheap, this way all your cards will have the needed airspace and will stay cool and below 70 degrees.

You realize the max for that card is 94c right? There is nothing you need to do, it just runs a lil warmer but still nowhere near any level that you need to worry about.

you dont want to run your cards  94'c period or even 80+

My cards run at 53C at 75%TDP and I have a custom fan curve.
But gamers reach above 80C when playing heavy duty games

I have experienced this one, but my cards is not identical, a founders edition and a gaming x, it reaches 80+ degrees on my 1080ti founders edition but the other cards stays at around 60-70 degrees, at first I thought this is just normal and thinking that founders edition is way hotter than the gaming x edition due to its fans, founders only have single fan while gaming x has 2, but later on, it gets hotter and hotter that the miner temp goes to red, so Im a bit worried, what I did is that I swapped them from their PCI-e slots, to my surprised, it cooled down, seems the main PCI-e caused it and the gaming X handles the heat.

Thanks guys, I am going to try this and let you know what happened.

So I moved the cards around, plugged  them to different slots.

There is always one card that is heating up more than the others. Does not have to do with any particular slot or card.

Still wondering why this is happening...

temperature under 75 degrees should be all considered perfectly fine, it is within the normal operation temperature  safe zone...
actually when you are using the card to play games, the cards could sometimes keep the temperature above 80 degrees...
just don;t let the cards stay over 80 degrees 24x7, then i think you might have the issues
