Hey all. I tried to search the forums here and couldn't find exactly what I was searching for. Basically, I set up a 6 GPU rig recently and can't figure out how to cool down the GPU's adequately. What I have is: 6 XFX RX580 and 3 fresh air fans coming in and 3 fans going out of the chassis. I also set the fans on each GPU to go to 100% at 75C. Even with all of this, I am running at 87-89C consistently. And from what I understand, this is going to either burn my cards up or create a fire hazard. So, two questions: 1) can anyone recommend a very high air flow fan that I can daisy chain with 4 pin molex and 2) any software tweaks I can use outside of afterburner?
After spending a butt load of money, this rig is going to be a paper weight if I can't cool down my cards.
Thanks for the help.

Even in the event that an attacker gains more than 50% of the network's
computational power, only transactions sent by the attacker could be
reversed or double-spent. The network would not be destroyed.

I thought GPU mining was a thing of the past. Well that shows me. Try under clocking your cards so the don't run so hot. Also look at your fans. Are they the largest you can get. And don't have three sucking air and three blowing it out. Two intake to three out would create better cooling I believe.

the simplest solution is just to use air conditioning
what is your outside temperature?

I've got a couple of 120's in my gaming rig which works for me but many prefer 180mm fans as the will move more air quieter.

And burn twice as much power than he does ? That's smart lol... No, the real solution is exaust the hot hair from the room. Great solution is a hyroponic culture tent with intake and outake fan (500cfm)

Are you even using the risers or have you placed all the six graphic-cards directly on the motherboard? Plus which miner are you using right now? Have you tried undervolting? Undervolting can greatly help in reducing the temperature levels, it does affect the hashrate a bit but with that, your GPUs will consume less power and will remain less hot.

To get the temperature under control, you have to: 1) Check the spacing between your GPUs 2) Fan settings, take them off from "auto" and manually set them on 65-75% or something 3) BIOS modding, mining BIOSes give you an edge over using the stock ones 4) Airflow through your mining room (cold air in, hot air out) 5) Overclocking/Underclocking settings Try to fiddle with those and you should get your temps. down

Never heard of any cryptonight coins hard- forking to be ASIC resistant? @Levieth02ng I can recommend box fans like this one: https://www.amazon.com/Lasko-3733-20-Fan-Box/dp/B00002ND67

I would go with some serious air flow. https://www.amazon.com/Hurricane-Box-Fan-Efficient-Lightweight/dp/B06XGSJ94B/ref=sr_1_1_sspa?ie=UTF8&qid=1529008912&sr=8-1-spons&keywords=hurricane+box+fan&psc=1and then --IF NEEDED-- something to suspend it in place: https://www.amazon.com/Weaver-Leather-Adjustable-Holder-Black/dp/B004BAXVUQ/ref=pd_sbs_468_3?_encoding=UTF8&pd_rd_i=B004BAXVUQ&pd_rd_r=FH26YR5YYPWSYC1MKKJ6&pd_rd_w=T8A73&pd_rd_wg=R80gc&psc=1&refRID=FH26YR5YYPWSYC1MKKJ6 I know you asked about daisy chain into molex but if you are just going to keep on using little computer fans you aren't really going to change much. You can keep using the little computer/molex connected fans but if you add the box fan you will move A LOT more fresh air and you don't even have to set it on a high setting. This should work in open air or even a closed chassis which sounds like you have a closed chassis. If you can run the chassis open-air that's even better but I imagine you might have some requirement to keep it closed. It would help if you could post a picture of your setup so we can see what you are dealing with. In my situation, I'm lucky enough to keep my stuff in a basement. I run box fans in the summer but no need when it's 0/32 (c/f) degrees in the winter

But to your question maybe I have, real life and that, though I do try to keep up with Bitcoin when I can.

Instead of cooling down your rigs, how about changing your coin algorithm ? Mining Cryptonote Coins and your rigs' temparature will decrease at least 7-8 celcius

That was isn't a solution. How if you faced most Cryptonote coins are being less profitable for mining? OP You have a few good advice above. I Super agree with this one: To get the temperature under control, you have to:
1) Check the spacing between your GPUs 2) Fan settings, take them off from "auto" and manually set them on 65-75% or something 3) BIOS modding, mining BIOSes give you an edge over using the stock ones 4) Airflow through your mining room (cold air in, hot air out) 5) Overclocking/Underclocking settings
You only need to implement this in your own ways.

You only need to implement this in your own ways. On whattomine.com we only compare profit of Ethereum-based coins with XMR and ETN. There are many cryptonote coins that 10-20% more profitable than ETN by now. However, most of profit calculator website is underestimating cryptonote hashrate. They only estimate 3960-4380 h/s for a rig of 6 x RX470. I usually have 4800-5000 h/s for this ( someone can make it to 5500-5800 h/s with more tuning)

If you put the 6 cards in a closed chassis you will need some superstrong server fans, they will cool your cards but its going to be very loud.
I´d recommend to rebuild your rig to openair if possible, much easier to cool and not so much noise.

Let say, most of Cryptonote coins are being less profitable for mining, what would you do? Break on mining for a while? These cooling systems must be work on every condition. So your suggestion isn't the solution at all.

try to under voltage this will give you some help
and you can use Large fan can be used to push the air out
the final thing you can use AC
