the goods were delivered quickly and was well packaged! I have a Thermaltake housing and wanted the fan above the signature in Case. You can run the fan with 5 volts then they are quiet or 12 volts then they come in full swing and you can also listen. I have today ordered a fan controller because I do not want to hear the PC is idle but wants to access the power of the fan while playing. I have an AMD FX 8350 GTX 970 Phantom and 16 GB RAM of the CPU is running with water cooling. Everything is sufficiently cooled with closed housing only I wanted above still neatly let air. I'm so excited ... I can cool down 5 degrees the motherboard when I run full fan. To me it is very important to cool properly during exercise and honestly at Battlefield and co. It is not bad if you can hear the fan.
