I can't tell you if it fits, but I strongly advise against it.
The heat generated by this card is so extreme that it heats my 25m² office from 21 to 25-26 degrees in 2 hours, without heating...

I had the 3080ti before and it was also noticeable but not as extreme as now.

I have a big tower and have the case open because it is so extreme.

Vertical mounting is also a thing with the new power adapter.
From what I've heard, most of the plugs that burned out were mounted vertically.

I hope my answer was helpful for you.
