HELP: Temperature high in custom closed air rig

[gameboy366]

Just today I transformed my 12*1050ti tower rig (6 on each side) into closed air rig with one exaust and 2 intake fans
 But to my surprise the temperature of gpus increased by 4 Celsius. What could be wrong ? My exaust is very powerful and so are my two intake fans. So the pressure should be fine. My rig is still not completely vaccum. There are many big holes that needs to be filled. Will making it completely vaccum decrease the temp ?


EDIT : Temperature increased by 7 celcius

your fans suck is the problem

If you want a closed air rig to work you need powerful fans that provide enough pressure to keep a constant air flow.

Basically you need a bunch of industrial fans as push and pull and need them to cover most of the case space.

Aww man, then what is the use of a closed air rig ? I thought it would decrease my gpu temp and reduce dust. Looks like money and time wasted. Temp. up by 6 Celsius. But I see guys making closed air rigs with no intake fans getting good results on YouTube.

I don't see how that's possible, closed up rigs with no intake fans... Surely they have some kind of intake, because they would make negative pressure without them. Maybe they have liquid cooling, but that is just too expensive and I guess no one is using it for mining cooling.

Maybe different position of fans could provide better flow of fresh air, which would lower temperature. Also, maybe number of fans that you have is not good enough. After all 12 GPU's produce a lot of heat.

[fanatic26]

You have 2 intake fans and 1 exhaust fan.


That is a giant red flag right there.


In crypto mining the standard is to remove heat. You remove heat by having more exhaust, and you dont have enough.

Passive intake and 3 exhaust fans would be the way to go.

Also, unless you are right on the border of overheating a 6c temperature difference is beyond meaningless.

[bernike]

You have a great mining rig sir. But that's pity if your temperature is going crazy. So you must get more exhaust, like two or three more. Because the heat turn around on the room, and the intake suck again before exhust flow away it.

I have found in the past that sometimes things are as simple as a bad orientation for how your rig is sitting. Someone I knew had their rig suddenly jump up 10c and it took them almost a week to figure it out. Long story short, as taking their rig apart, cleaning it, putting fresh software on it and even RMAing a couple cards they realize that they had scooted their rig a few inches closer to the wall without realizing it. Being a little closer to the wall, the exhaust acted weaker than it should have, the air wasn't able to escape as well and so it created a heat cloud around the rig's exhaust. I would listen to the previous suggestions as well, but sometimes it's as simple as not giving your rig room to breathe.

RMA-ing because of temperature 10 degrees higher? Now in my country that would be the day. RMAs are so strict here locally especially now that they know some people use GPUs for mining. In fact, some computer stores now only give 3 months warranty to GPUs that have been used for mining. I guess if you look sketchy they can simply say your GPU was used for mining then refuse any service or RMA after 3 months has passed.

I've done RMAs for such things in the past and I know others have as well; note I live in the United States where warranties are normal for the most part except for certain mining cards and most major sites offer returns.

Exhaust is absolutely the issue, and although this is a bit unrelated to a GPU rig the SP20 BTC miner utilized just one exhaust fan (albeit with good static pressure and high RPM) to remove heat, and it worked fine. Increasing the number of exhaust fans on your case should do the trick if you're willing to spend money for a minor temperature difference. Four degrees isn't much, and leaving the rig as it is likely won't cause any catastrophic failures on its own.

I'm also from the United States, people get very finicky over just about any and every thing. If something is not operating at optimal performance, then people are likely to RMA their gear. If the warranty is coming to an end, then people are likely to RMA their gear. I have no clue how things work in other countries, but for the most part if the hardware is not operating within 5% of optimal performance there will be an RMA request. Usually the companies have no problem with this, either, but if they believe the damage to be your fault or intentional then they will not grant you a replacement. I've never heard of a warranty that short, but I guess that's a cultural difference for you. Over here, they wouldn't put stipulations such as "if used for mining", because that's an extremely strange restriction to put on your RMA and could be abused as you've already laid out.

It seems the consensus, from the information OP has provided is exhaust.

Another way is to try to lower down room temperature! It actually helps a lot for closed rigs

[nc50lc]

So, it's a closed rig, I guess to avoid dust?
If the room temperature is high, a closed system has more consequences than advantages. An AC will definitely work to your scenario, though.

If the room temp is fine, it's definitely the internal airflow. Either your fan sucks or positioning problem.

Like this for example, you can install an AC if you're using a closed rig casing.

[namelessaaa]

"closed air rig" is the problem.

Usually, 1050ti*12 is without any problem at opened air rig, 1050ti's fan is enough for cooling itself.

But at closed air rig, you need lots of additional powerful fan to send cooler air to the GPUs, generating noise.

However, you have buy it, so give it more fans and enjoy the noise.
Or you can ignore the temperature less than 70 degrees Celsius.

I guess that in some cases that would be good thing to do. But in OP's case, lowering room's temperature is not necessary. At some point he can do that, but it would require more money. On the other hand, he can install few exhaust fans and his problem will be solved for less money. Not to mention that electricity consumption of AC and exhaust fans is not the same.

Of course if I had the money and place for AC then there would be no need for making it a closed rig. People are saying to lower the room temp like it's very easy. I would have already done it if there was a way. I am gonna add another fan in front and see what happens.

One thing for sure I will never make another closed rig. Money spent on fans and sheet and my labour + more electricity bill + more noise = not worth it.

But my rig looks badass.

Wise decision, seems you don't know a shit about cooling.

Your comment is not necessary and its only a shit post, because it helps no one. If you read whole posts (from which you quoted only small part), you will understand that for OP its simpler and costs less if he builds open rig. And I support his thinking, because closed rig is not always best option. Also, we are here because we want to learn and need help in solving problems, not all people are all-knowing like you are. So next time just stay silent...

Word of advice, next time before you decide doing something, take some time and research a bit more about the thing you are interested in. That way you will prevent most of mistakes.
But I don't think you made big mistake with this choice. It will require some money for more fans yes, but at the end all of that invested effort will pay out. Also, I guess you wanted closed rig for a reason and not only because it looks badass

Yes absolutely but it was not a big investment anyway, hardly $33 total for fans and fiber sheet. I bought 3 intake fans and used only 2 so I will use the remaining one as an additional exhaust. I underestimated the amount of heat generated by GPUs as I thought that the small exhaust fan was made for bathroom so it will definitely get the job done for a small rig(compared to size of bathroom).

The project will be a success anyway. My max GPU temp was 54C at 55% fan speed and now it is 59C at 59% fan speed during afternoon(38C). It will protect from dust and my room already feels cool because all of the heat goes out of the window from exhaust.
