High amperage causes heat, and when fans are controlled by relays those amperage spikes cause high heat in a short amount of time.” We talked with Mike Murphy at Derale, and this is what he had to say, “Pulse width modulation eliminates amperage spikes in an electrical system. And because the current is lower, so is the heat, and the wires stay cooler. The PWM works on what Derale calls slow start technology, in which the current that goes to the fan motors is not a blast of current, rather it arrives in a controlled manner from the PWM. Derale Performance has a product that can help take that initial shock out of your cooling fan’s electrical load with its PWM Electric Fan Controller.

We’ve all heard the saying, “it’s not the voltage that gets you – it’s the amps,” and that amperage is what can take its toll on your electrical system. As long as that's within spec of the hub you use, it should work fine.The more power a component requires, the more current it will require, and that current is delivered in amperage. Max input current: 0.14 amps x 10 = 1.4 amps. Max input power: 1.62watts x 10 = 16.8 Watts total The A12x25s are pretty efficient, so it shouldn't be an issue. Just make sure the total current/wattage of all the combined fans doesn't exceed what the fan hub is rated for. I'd probably lean toward the deepcool one, it has better reviews overall. I've not personally used either, but they have decent reviews. Thermaltake and Deepcool both make a 10 port PWM hub. This shouldn't be a problem for a water cooled build with multiple radiators. Plain hubs are much more reliable and simple, you just have to know that everything connected to it will be getting the same pwm speed signal.

I've tried both Corsair and NZXT's smart fan controllers, and returned both due to issues with the software.

I've had nothing but bad experiences with the smart fan controllers, where you can control each fan header individually through software. I'm assuming you're talking about a PWM HUB and not a PWM 'Smart' fan controller.
