An industry-first, they can actually operate in fanless mode

Cooler Master may have gotten its namesake for its fans and heatsinks, but its power supply line is in no way lagging behind, as shown by the new Silent Pro Hybrid Series.

In order to produce as little noise as possible, coolers and things that use them try to find special fan bearings and construction elements that will reduce friction and vibration during operation, in addition to making rotary speed user-controllable.

What Cooler Master decided was to go one step beyond that, actually building a series of power supply units that can work with their fans turned off.

In other words, they produce absolutely no noise because there is no rotary movement to cause it, at least at small loads.

Basically, the “fanless” mode has the fan stay inactive until the PC reaches loads of more than 200W, at which point the safe mode activates the spinner, based on the energy and heat load level.

Cooler Master implemented another benefit, that of a 5.25-inch bay fan controller module, for on-the-fly control without any unnecessary strain on the mainboard.

As for the fan of the PSU itself, it is a 135 mm (5.31 inches) SuperSilent Hydraulic Bearing model (the fan controller can handle three case fans at the same time as well, on top of this one).

There are three power supplies in the Silent Pro Hybrid Series and all of them should already be available (October 4 is the date in the press announcement).

Their power outputs are of 850W, 1050W, and 1300W and, in that order, the US prices are of $199.99, $249.99 and $299.99.

Exchange rates say that the above sums are equivalent to 150.25 Euro, 187.82 Euro and 225.38, respectively, but European prices don't often reflect this, usually being of just as many Euro as US dollars, or close to it (like how $499 tablets sells for $479-$499 Euro).
