Which 120mm Noctua fan is best for the rear vent of my case? (Air flow is normal front to rear).

Hi mate! I've got the noctua industrial PPC ones which is moving a lot of air when on full speed, but it is noisy indeed, but if you have a motherboard that has the 4pin fan connectors and you can set the speed then this fans are truly amazing! I've got all my fans from noctua and when I'm playing games I used them on 75% of their speed and you can bearly hear them. Otherwise you can get the supersilent ones but they don't move as much air as the industrial ones! Have fun!

Can i use this on the same pwm circuit (using the extension and y cables) as the nf-a9 92mm fan (different rpm)?

Y cables typical only have the 4th pin on one connection, and thus the other doesn't report it's rpm to the motherboard or controller. The second fan just receives the same voltage as the first. It'll work at loosely the same percentage as the first fan, but that rpm will obviously differ. Put the more powerful fan on the fully enabled connector and the second fan will always be quieter. Other way round and it'll always be the faster one.

Does it come with a filter?

No it does not, IV never come across a fan that does.....
