HELP: Temperature high in custom closed air rig

[xparetols]

In my opinion there are two choices - either you put intake fans so that they flow the air across the cards removing hot air, and at the top you have passive exhaust, or you have active exhaust and passive intake at the bottom of the rig so that the flow passes the rig. If it is closed, you dont need both intake and exhaust, one is enough.

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

After attaching fiber sheet and fans :    https://prnt.sc/j4nwh1     prnt.sc/j4nx6z       prnt.sc/j4nxh3

You don't need exhaust AND intake fans.

Do one or the other.  Not both.  Also, your air needs to circulate everywhere.  It's not just the graphics cards that generate heat.  If you look at all the industrial miners they are all open air.

One thing for sure I will never make another closed rig.

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...

Oh yes all that advices/shitposts, seems you don't even know how GPU cooling solution works.   It doesn't matter how many FANs he is gonna mount this won't work.   
I'm running a closed RIG with 6 GPU, you know just with 3 FANS and max. Temp. is 47°C with ethash and 41°C with cryptonight, no AC or anything else.

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.

This is correct, you need to create negative air pressure inside the system (more exhaust than intake).

What happens if you have positive air pressure inside is pockets of heat develop that get stuck in place. OP this is almost guaranteed to be what you are experiencing.
