What are the temps in that?

closed case with OEM fans it was getting to thermal limits.

open case with active cooling, it sat around 68-71*. It sat in his livingroom; I think he's put wifi on it and moved it to another room by now.

We will be putting in high CFM fans in place of these low speed ones and it sounds like that should fix closed-case temps.

I put 3x UltraKaze 120mm 130cfm fans on the front. reversed air flow of the case too. they stay at a steady 73C mining.

Do you have the entire unit closed up with those temps?

yes, it's closed up and gets those temps

I'm using the rosewill 4000 with 6 x rx 470 cards msi oc.
asrock pro btc 2.0

It seems to be working ok with 1 x 750w rosewill psu
i modified the memory timing and downvolted the gpus by about 97mv.

So far has been running 2 days nonstop with lid on.

in my first reply you can see the insides, i mine zclassic currently and they get to about 73c-78c depending if the door is open or not for the room. my hasrate is 1750 straps unmodified but undervolted (brings power and temps down Cheesy

). like i mentioned i have 6 high cfm server fans in and it forces the air through the cards, i didnt pin the card fans to 100%, they run their usual 40ish%. the case fans are doing the work.

Do you know what wattage you pull at the wall?

looks like a GPU BBQ Griller to me. the cards are becoming pretty HOT in this enclosure, don't they?

Is there any positive or negative to not using all risers and putting 1 or 2 GPUs on the main board?

the problem is airflow; the cards want to push the air out of the back of them, so if you have them mounted facing both directions, you are working against that flow with the ones mounted in the mainboard (as one is in this photo).

I need to repair a riser so we can mount that one card with all of the others. Till then, it sits there; Its being run open-case with a fan blowing down on it from the top.

Higher flow fans are needed for the front panel.

I knew forcing air was the only way with a enclosed case like that. My next project is using a 6 tier shelving unit. 12 cards a row 2 boards. Someone on here is talking about daughter boards so it might be 1 mobo for 12-16 cards. We will see tho.

The idea of enclosed is nice but you can't escape the sound. Unless you build a soundproof box like I did about 5 months ago for that setup in the picture. It works very well and you really only hear the air going in and hot air coming out. I was surprised with the result. I'll have to find the pics

I'm thinking of using this case for 7 MSI RX 470 4GB Gaming X cards. I'd mount 2 on the MB and flip the other 5 and reverse all the fans in the case.

How do you know you need higher flow fans?

With the case closed, the cards were thermally regulating and running hot. They don't have the CFM. Simple to replace them. IDK why they are so weak.

Then again, these are running a higher TDP than a lot of the newer cards; but... he wanted hash density in the machine; plus better resale value in the future. I don't knock that at all.

Im jealous of that back panel. I think i can finagle something like that. quite a nice way to do it. Gets airflow sorted very well too (nicer to have it out the back instead of front).

i took a rosewill and did a 280x build three years ago. still running now Cool

your is a different take, i wanted blow fast air so the bar in the middle has 3 fans, 6 total 7000rpm server grade 120mm fans. the backplate was a special manufacturer run plate from china, a guy from another company helped me out alot. the 1080s look cool lots of space good job!

ps never posted a pic hope it works.
