is it a bad idea to place a gpu fans up? (feddit.it)

I'm hacking together a gaming/fluid simulation pc from a lenovo thinkcentre m700 sff. I've already got everything set up. The problem is that the only riser i managed to find has a 90° bend to the left. (Looking from where the bracket would be.) The problem is that like this my only way to make it fit is to turn the 3060 fans up. With the extra psu powering it under it. With ~7 cm of clearance. (i'll make some stands to hold it properly) What i'm not sure is if it's going to make a big difference that it's going to push hot air downwards. The power supply fan runs continuously and it draws air downwards and out of the back. But i don't know if it will be enough.

What do you think. Is it going to make it get hotter a lot?

Heat likes to go up, can you reverse the fans to have them draw in air from the bottom and push out the top?

I'm not talking about extra case fans. I'm talking about the fans integrated in the gpu. + the integrated fan in the psu I can't really flip those. The most i can do is put another fan in the side of the space between the gpu and the psu to draw air outwards.
