I have the haf 912 case with 3 120mm outake fans at the back.
I'm waiting for my 200mm front intake fan to come. Will this provide adequate airflow?

Also until the 200mm fan comes could I put one of my own air fans in front of the case to blow cool air in?
Would that be fine it blows really well.

Sure. Just be sure to watch for dust bunnies using an exterior fan - it's going to move a lot of air and will pick up anything floating nearby.

Edit: You might even consider changing one of your 120's over to intake.

It is airflow that counts.
I would think that the 3 120mm exit fans would be sufficient.
That is about the equivalent of a 200mm fan, so I would leave them that way.
I doubt that adding the extra 200mm will help the airflow much.
From a noise point of view, you could remove the rear exit fans, use the front 200mm as intake and probably do just fine.
Are you having a heat issue?

What I tried to say is that 3 120mm exit fans has about the same cooling power as one 200mm intake fan.
You really do not need both.
Do not be disappointed if your new 200mm fan does not do much for your cooling.
I usually prefer an intake fan or fans with an air filter and no exit fans.
That gives you a positive pressure situation which keeps the most dust out of your case.

Oh neveind it just jumped to 70%!
Everything smells like new computer though.
The air coming out smells like the plastic on the fan
But my room has one window and my pc is in the corner so that's probably why the smell is gathering up there
