duke-of-bytes wrotedo you have any experience with silent 120 mm fans ? i read about the NF-S12B redux-700 and they are cheap and silent ( around 12 euros each ) do you know any other good and cheap model ?
Lemme check, I have a 120mm fan, it is silent - I forget the brand though.
Would you be interested? If so I will look it up and give you the brand.
It is barely used and I had researched it and bought it on ebay specifically because it is quiet.
However most important is a good airflow, and fresh air intake.
These quiet type of fans do not work well when the airflow is very constricted.
So my advice is add a silent fan in the back, but figure out how to have an air intake in the front and at the bottom - drill some holes in the bottom if you have to.
I also have a couple of 120mm thermaltake fans.
