My case is an Antec P182 fitted with 3 Noctua NF-P12 fans in the upper chamber (1 intake, 2 exhaust). CPU cooler is a Thermalright Ultra120 with 1 x Noctua NF-P12 fan pushing air through it.
Now i guess in it's current set up the air pressure is negative (more going out?) Also as all the fans are running at the same speed, there isn't going to be any turbulence, especially from the cooler to the rear exhaust fan.

Now my question is that if i were to change my CPU cooler fan to 2xAkasa Vipers, which run faster and push more air than the noctua's, would that have a negative impact on the air flow in the case?

should i just stick with all the same fans or those that push a similar amount of air?

Cheers
 
Well, i got 2 Viper fans recently, for a h50 which i couldn't install due to problems removing my current backing plate (long story). So I'm thinking of using these fans in a push/pull config before i RMA them.
I don't have any problems with temps. Q9550 @ 3.8ghz and only hit 55°C on load with my current set up. I thought if i swap my Noctua fan on the cooler i may drop the temps a few degrees.
 
I should think it would... May have to loose your rear exhaust fan but the 2nd fan on the silver arrow would be so close to the exhaust vent it would be doing the same job really

failing that, angle it facing upwards so it vents via the top exhaust

Ultra120
Length 63.5mm × Width 132mm × Height 160.5 mm
Silver Arrow
Length 147mm x Width 123mm x Height 160mm

Best way to be sure is to grab a ruler :)
