I'm currently working on my new PC build, which already has 3 fans at the front for intake and 4 fans for exhaust (3 on top and 1 at the rear). I've noticed that my room tends to get hot and dusty, so I'm wondering if it's worth it to add bottom fans as additional intake or if I can just relax and enjoy my setup the way it is. What do you all think?

If your case has extra slots for fans, why not fill them? Fans are relatively cheap, and it could help with airflow!
If your temps are alright, maybe just enjoy your build. It's not a big deal if you're not running hot.
In most cases, you don't need more than 1 or 2 case fans. After that, adding more just doesn't really change the temperatures much.
The temperature measurements matter the most. If your system runs fine, then there's no urgent need to add those bottom fans, unless you're particularly concerned about dust.
It sounds like you might have too many exhaust fans. You could be creating negative pressure in the case, which means cool air might be getting sucked out before it reaches your CPU or GPU. Consider removing the top exhaust fans or flipping one of them to be an intake if it's filtered.
