I've tried so many different setups over the years and finding a balance between looks and temps is a massive headache. When I first got a heavy card, I went through three mounts before I found one that didnt turn my case into a literal space heater. Since you're on a budget and have that specific case, I'd look for the Lian Li O11D-1 Vertical GPU Bracket Kit PCIe 4.0. I found one for about $70 recently and it's rock solid because it is literally made for your chassis. In my experience, official kits usually save you the most stress. I once bought a generic one to save a few bucks and the sag was so bad I thought my PCIe slot was gonna snap. Not fun. Plus, that Lian Li kit keeps the card far enough from the glass that my temps stayed decent. Just make sure you've got bottom intakes cranking to feed the 4080 some cool air. It'll definitely be ready for your stream.

Yo! Just saw this and I am super hyped for your build because the 4080 Super looks incredible! Like someone mentioned, that O11 case is a classic but it gets tight fast. Quick question tho—is it the original O11 Dynamic or the Evo version? It makes a huge difference for clearance and which brackets actually fit right. Quick technical tips for airflow:

• Always mount as far back from the glass as possible to avoid the oven effect.
• Ensure your bottom fans are set to intake to push cool air up into the GPU fans. These are fantastic alternatives that should stay under your budget:
• Phanteks PH-VGPUKT_04 Vertical GPU Bracket PCIe 4.0
• Lian Li O11D-1 Vertical GPU Bracket Kit PCIe 4.0 I would love to see photos once it is done! That 4080 shroud is too pretty to hide.

Honestly, skip the universal brackets if you are worried about sag and airflow. I've been running the Phanteks Universal Vertical GPU Bracket with the Phanteks Premium PCIe 4.0 Riser Cable for a while now, and it is rock solid. Since your case is an O11, you really need to prioritize the distance from the glass or those fans are just gonna choke.

• The Phanteks kit is super sturdy and handles heavy 3-slot cards without that annoying sag you mentioned.
• If you are worried about the cable, it is honestly better to just buy a high-quality riser separately if the included one acts up, but the Phanteks one has been totally reliable for me at Gen 4 speeds.
• Try to mount it as deep into the chassis as you can; moving it just an inch away from the glass dropped my temps by like 5 degrees in my old O11 build. Good luck with the stream, hope you get it sorted by Sunday!

Honestly, I totally feel your pain with the whole vertical mounting struggle! I remember when I first tried to show off my own build, I dealt with the same exact thermal anxiety. It was so frustrating watching my temps climb, but honestly, once I finally got the spacing dialed in just right, the difference was night and day. It is honestly such a rush to see those fans actually pulling fresh air instead of just choking against the glass. I ended up going with a setup that allows for some serious adjustment and it made all the difference in the world for my airflow. My temps dropped like crazy just by moving the card back even a tiny bit! It really is worth the effort to get it positioned perfectly, especially for a card as beefy as yours. Dont stress too much, you are gonna figure it out and your stream is gonna look absolutely amazing once everything is finally running cool and quiet!

> I saw the Cooler Master Universal V3 and it looks okay because you can supposedly move it away from the glass but then I read a bunch of reviews saying the bracket is super unstable with heavier cards and sag is a nightmare. Honestly, I think those reviews are way off or they just didnt tighten the screws enough lol. I have been using the Cooler Master Universal Vertical GPU Holder Kit V3 PCIe 4.0 for months with a huge triple-fan card and it is totally rock solid. No complaints here. The best thing about it is that sliding mechanism... you can basically shove the card way back toward the motherboard so it has tons of room to breathe. In my own O11 build, my temps stayed almost identical to horizontal mounting because of that gap. It is usually around $60 on Amazon so it fits your budget perfectly. I havent had any issues with the riser cable speed either. If you want something that actually works without the sag, this is the one imo. Just make sure you lock the sliding rails tight once you find the sweet spot.
