The TWV 480 has two cooling fans. One draws air from the inside of your computer and the other blows the heat out the back of the system. The fans used in the TWV 480 are not your typical fan types. They are actually quite powerful and when set on high speed they're very audible.
The rear fan is rated at 1300 ~ 4800 RPM and can be controlled by way of the fan controller on the display front panel or automatically. If you select automatic mode, the rear fan adjusts its speed based on the temperature detected by a thermal probe.
When the PSU detects 25 degrees Celsius it will run at 2500 rpm, and all the way to max speed around 70 degrees.
Thermaltake has done a great job of keeping all the wiring neat by way of sleeving.
As for the wiring, you'll find plenty of plugs, nine actually, to power your fans and what have you.
