Question RTX 5090 FE vertical mount - LM & Vapor Chamber questions ?

[uplink-svk]

Hey there mates! 👋🏻

Any ideas on RTX 5090 FE vertical mount regarding LM & Vapor Chamber? Is it super bad? I mean, will the LM flow down/drip eventually? Is the vertical mount bad for Vapor Chamber performance? My TOP temperature in FurMark 2.X were 78°C on GPU and 88°C on memory Junction.

I know it's heating up my motherboard a bit.

What are Your thoughts gents?

Thank You for Your eventual insights! 🙇🏻‍♂️

P.S.: Here are my data.

And here are thermal data of 12V2x6 connector PSU side, 12V2x6 cable, 12V2x6 connector VGA side, motherboard VGA airflow heating impact. I've been burning 575W for about an hour in the photos.

The video showcasing the RTX 5090 FE by Gamers Nexus addressed it. You're going to be fine when mounted vertically or horizontally but I'd mount the card horizontally and negate the need for the riser cable which often times is a failure point, coupled with the negation of warmer air being blown on to the motherboard.

Thank You for Your insight. I've seen that video, but since it's the only opinion out there, I don't put much trust in it. I mean Sony told users that PS5 will be fine standing and it leaked multiple times and degraded, Asus told users that LM will be fine on their VGAs' GPU and it went bad really fast within a year, etc. I know that FE won't leak, but LM might flow down. Anywho, I gave up on FE, MSi is a lot better besides size and design...
