Random question: thoughts on how close GPUs be stacked to each other on a mobo?

Stacking 4-5 GPUs (1x2060super, 4x5060ti) on a gigabyte mc62-g40 mobo, which has 7x PCIe 16x slots. Might end up actually taking out the 2060super in favor of the 4x5060ti, but they seem pretty close to each other when they’re plugged in with only one PCIe slot of space between them. Is this like a fire hazard or might mess up the life span of the GPUs over time, or is this not a big deal as long as I undervolt a bit? Wondering if I’m overthinking all this lol

2xRTX3090 for a start

5060 Ti 16 GB is baiting people so hard with it's miserable 128 bit memory.

Yepp, they really have no clue what to build and how to use it well.

You’re overthinking it a bit, dense GPU setups are pretty common. Main thing is airflow - the middle cards will run hotter, but with undervolt + a couple good fans it’s usually fine. Just watch hotspot temps, not only core temp.

As long as they are not overheating it doesnt matter

Going to be devil's advocate here. There isn't really a way to know if anything other than the core or memory is overheating. The power delivery could be frying itself and poof goes the card's life span.
Anyways though simple fix is to throw a zip tied fan on it, undervolt the cards, and/or set GPU temp limit to like 90C(this one costs performance if they reach that temp though).

Use risers?

Just use dual slots blower cards

louder than just doing what he's doing and adding a few extra case fans. they sound like jets.

Shouldn’t matter 5060s are needed so run colder open top?

They can stay right next to one another if they have vortex fans. If not, The new mobos have four slots between the first and the second PCIe

I have this same board on order - delivery later this week and my plan is to make sure that each GPU gets fresh air by having a fan that blows from the top of the GPU (so that would be from the side if you have a tower standing up with the motherboard vertical). My longer term plan is for 4 dual width GPUs (starting with 2 though).
There's no real way around the two center GPUs in my 4-way GPU setup will be hotter than the others. My goal is to make sure they're within spec and after that, I'm not going to try to optimize harder unless I see issues.
