Q1) Is adding a 120mm fan to A or B better?
Q2) Is adding two 120mm fans to A and C better? or A and B better?
The blue fonts are 120mm fans I intend to add for air intake into casing. I intend to add either 1 or 2 fans.
The red fonts are fans that are already in my casing CM 690 II Advanced
Other suggestions?
Add A & B and forget about C as it will likely just screw with the flow from the 140 mm and the new B fan
Definetly B, and A only if it is filtered.
I don`t even see holes for A, but I assume they are there.
As Alan says, C would be useless.
Orange arrows will be where the fans are, and air direction arrows for my casing. Thanks all
There are holes and filter. See the third pic here Cooler Master CM 690 II Advanced review - Product gallery - Exterior
I have one 140mm PWM fan, should I put at the front, top (nearer back) or top (nearer front)?
I have never use a PWM fan before, I bought it because the normal (non pwm) fan is sold out.
A= might need to be a 120mm fan depending on the psu and wiring and how much room that takes up
Fit as many 140mm as you can
The only other 120mm is on the back
C= yea I don't get that one at all
My hhd rack had a floor on it so there wouldn't of been anywhere for the air to go
If you take the hdd rack out then it might make sense to put a fan there.
Case fans I would use af140 or 120's very quite fan
Think about cpu liquid cooling they work best as a intake pulling cool air in
The most logical place for it is in the floor some versions already have a 120 fan on it like the Corsair h80
Hydro Seriesā„¢ H80i High Performance Liquid CPU Cooler
But you can put as an exhaust on the back top it's well worth getting
Or a h110 gt on the top
