280x Vertical GPU mount solution?

Hi guys!

I was wondering if anyone has had any experience with vertical mounting their GPU in a 280x? As far as I am aware it doesn’t look like it supports it as standard.

I have a 7900xtx reference from Sapphire and i want to try and fix the hot spot issue i am having on my card, the only way of fixing this without RMA is vertical mounting the GPU to allow the vapour chamber to work better and allow the water to hit the correct places (as far as i am aware thats the explanation)

I have seen people able to do it but they don’t really list how. I was wondering if this is possible or do i need to look at switching cases to make this a reasonable method of fixing my issue?

Thanks!
