Topic: What minimum fan speed do you set your GPU rigs to? - page 2. (Read 1328 times)
For me auto fans , gpu target temp <75 C , all good
I run 60% on most everything, up to 70% on really hot cards. If you need more than that I think another solution is needed like looking at spacing/ambient.
All of my 4+ year old cards are AMD, the oldest NVidia cards I have are "only" about 2 years old and spent a lot of their lifetime Folding (which tends to be HARDER on a cards than most cryptocoin algorithms are).
I've had many GPUs survive 4+ years of high-load usage running in the 70-75C range.
Targeting 50C is WAY excessive, and the only cases of 50C GPU temps with 50% or less fan I've ever had were on gear in an A/C room on risers, or the "outside" card in a "no case" rig with all cards on the MB, or a rig with ONE card in it - and the card was set to run at "efficient" settings.
Water cooled/hybrid is another story, water cooling the GPU is a lot better at keeping the temp down - at a significant cost for the higher-end cooling solution.
Were those AMD or Nvidia cards? I wanted to be on the safe side with 50°C but as it doesn't affect performance, it can't be a bad thing.
wow 60-70°C for a GPU, seems very hot. Has anyone ran such temperature for more than a year? I keep my GPUs around 50°C (or even lower in some cases) with a fan set to 50%.

Better to target temperature rather than fan %. Under 70°C is recommended, personally I have all my cards target 66°C which is easy to achieve in most cases.
Depending how your cards sit some fans will run at 35% some at 80%, but fans are cheaper to replace than silicon, so don't worry if they are at a higher percentage on your rig.
For AMD I use OverdriveNTool to set a target temperature.

I'm using TDP 65%, fan auto and my Gigabyte Xtreme 1080ti water cooled runs at 39C. Evga branded gpus FTW3 goes between 60C-63C with auto setting.
been running my fans at 70% - cards stay around 50-55 (rx560's)
The minimum speed of rotation of coolers on my Asus 1060 6gb video cards is 10% in winter (at an ambient temperature of 0 degrees) and 50-60% in summer (at an ambient temperature of 30 degrees). Cards after Undervolting.The temperature of the cards themselves does not exceed 65 degrees.

Very wide variation depending on Ball Bearing or not, and on the specific card.
I've had a couple Sapphire cards with very small fans that need 80% to say reasonably cool run at 70-80% for 4+ years without issues.
I've had Gigabyte 3-fan Windforce models die in a year or less with 60% fan.
I generally aim for cards to stay in the 65C range on my AIR CONDITIONED workbench, so that when they go in the "production" room that runs a lot warmer in the summertime they'll stay in the 75C or less range - and the fan speed ends up wherever it needs to be.
Riser rigs help a LOT on that, much better airflow and less heat hangs around so you can set your fans 20% lower in many cases while seeing LOWER temps.

I set mine to auto.
But temp is 72C and fan speed 30%.
Using trixx.
Strange

I use 60% for my nvidia cards, the temps are under 65C.
For AMD VEGA, auto fan speed works well, I just set target temp, always 2200rpm @55C, 1600rpm@65C.

GPUs are not created equal either because of manufacturer, model, version number, thermal paste application, etc. But even if you already have GPUs of the same exact specifications, there are still chances that their temperatures will vary. So fan speed will really have to vary per GPU.
What works for me, in my local ambient temperature, is a minimum fan speed of 60%. I suggest you gradually check what temp your cards are running with different fan speeds. You will really have to do this yourself and not rely on other's fan speed.

I did not OC my GPU, so I just put it as automatic, no changes to fan speed.
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.
I run mine at 90% all the time. I'd much rather have to replace some cheap fans on my GPU than the chip itself. Also, it helps disperse heat faster which in turn keeps the surrounding area cooler. However, the profitability of a GPU mining rig will most likely drop off long before there there's any issues with the hardware, at which point you'll probably want to unload your old cards to gamers so you can upgrade to the newer cards with better hashrate/W ratios. So, I wouldn't worry about it too much about it.
That sounds good in theory but who wants to buy a card with a broken fan, and its not that easy to replace some fans , alot of the newer cards are custom deals , not any random fan works with the screws and connections. IMO any card whose fan dies in less than six months
to a year even in constant use need to be avoided.
All i can say is avoid Gigabyte (lower end ones RX and Asus)
if I run windows I set at 75% and try to keep temps under 70
if I run smos I set at 50% and set card temps to 69/70 and the software moves fans to what is needed

75 degrees should be fine , I have enough issues with fans going out at that target temp let alone 60 degrees for a target temp.
Although sometimes i wonder if the start stop of the fans using the target temp is bad for them.
In my experience
AMD :
Gigbabyte - terrible fan quality 1 out of every 2 seems to break.
Saphire and MSI - best.
Power color not too bad only one of 80 cards had a broken fan
Asus - bad as well but no where near as bad as gigabyte.
Nvidia
EVGA best
ZOtac worst
the rest are all pretty good.
