Discussion Improving airflow on my desk around SM550

I'd like you ask you for your advice :)
So, I recently moved to SM550 with Vega 56 GPU. All fine but since I have small desk and big monitor, the case is pushed against the wall from the GPU side (and back side). As a result, when I play games, the hot air does not really have where to go and the GPU ends up throttling down do 1200mhz. This is impacting a lot the gaming performance. Of course, this is undervolted. The fan can't go above 60%, as it gets loud and disturbs the family :)

So, I am thinking of putting some 120mm fans (3) on the side and the back of the desk, just below the top piece. Like this:

The question, before I ruin the desk, is if this will make any difference at all. If the improvement is just marginal, then I will skip this and think of other solution.

I don't think think this would do much, but I have no knowledge of CFD. How much of a gap is there between the desk and the wall?

It is between 4 and 5cm on the side. On the back it is more, which will make it harder for the air to move "more" up and also there are the cable there. But on the side, having in mind that narrow space it might create more pressure - this is why I was thinking that it might help the hot air to escape a little faster.

Is the gpu a blower syle gpu (only has one fan, exhausts air out the back)? If so moving the case towards the front of the desk could help.

Also, maybe putting small (40 mm or 60 mm) fans between the desk and the wall pointing up would be more effective than larger fans blowing at the wall.

You would need some sort of ducting to direct the air up towards the case, and since the space is small, would probably increase pressure, which may help
