It controls four fans, has real-time power consumption meters, and an alarm.

We appreciate additional help cooling down the computer as much as anyone else, for obvious reasons . But the way things are going, external PC fans may be getting more complicated than the climate control system for our entire building.

Take this multi-fan controller from Zalman, for example. It looks like something out of a Doppler weather center. The box can control four fans, indicates power consumption in real time on a color LCD, and even sounds an alarm when a fan stops working, according to Gadget Grid.

But what hooked us is the animated propellers. Hours of mesmerizing fun.
