The first thing that surprised me was the size! I've been a tower PC but it was really tight [....]
Electricity are after 1x 8 pin and 1x 6pin, so new PSU. Since my case anyway already 6 fans were the other three on the graphics card to me relatively unimportant. If I then, however, start a benchmark or with Thunder Master increasing the fan speed I have a starting Jet from BF4 beside me. What can I say, I love this sound: D
Otherwise have been even under full load never louder than my other fans. Everything was top!

Also I have clearly in this card when it is running at full load Spulenfiepen. In normal operation, all is quiet.
