Finally, and although the three fans provided were replaced with the Be Quiet! Pure Wings 2, I managed without difficulty to integrate a configuration combining silence and performance.
It's simple, with an i7 4790k coupled with 16GB of ram Kington Savage, a GTX 970 from Gigabyte, a crutial MX100 SSD, power supply Corsair RM 750 semi passive and Corsair H90 water cooling system (fan replaced with a Silent Wings 2) the set does not exceed 28 ° in the office and less than 50 ° in. The whole, still in silence.
In short, I recommend this case in view of its many qualities.
