I've 2 RX 6700 XT. It's a dual GPU setup.

1st one gets hot like hell because of the hot air it takes from the 2nd and the 2nd still runs a bit too hot.

The 1st one becomes so hot that i can't run the project since it goes in thermal throttling.

Bigger MB with more gpu slots so you can spread them out a bit? The other is to swap the back plates of the gpu's so you can use water cooling.

ps I asked a guy in another group if he'd give you a better answer as he is FAR more experienced in that type of thing than I am, he may ore may not reply but either way give him a couple of days.

Thank you. Any help is welcome.

Now i was thinking about undervolt.

Is it ok for BOINC projects?

You can use a PCI-E extender, so that the GPU have "more air" between them.

Yes but you could lose some productivity, YES for some people it's worth it anyway especially for those who have very high electricity rates.

Let's say there's no space in the case. I can't move or add anything. I did some math now and sadly there's no space for a liquid cooled solution.

Seems that software is everything i can change.

No problem for the productivity loss since the alternative is not running the project. Especially if less productivity also means less electricity and so expenses.

I think i found a solution for now. -6% power. Maybe in summer i'll also add a -10% voltage.

Thank you guys.

Lots of times you can find new/used cases pretty cheaply if you aren't pushed for time, which you aren't, so if you have the time and know how you can swap things over to a new case giving you the room you need.
