Verax GmbH P14 Silent Heatsink Review

Verax Ventilatoren GmbH of Villingen-Schwenningen Germany make one the most unique zero-noise fans in the marketplace, and accomplished this feat by tossing out convention, and starting over with a completely new impeller design.

So quiet is the Verax CAIRdB fan that you literally have to hold it up to your ear to hear it - there is almost no discernible noise signature. The trade off however comes in terms of cost, and in measurably lower airflow to that of standard hi-RPM axial fans.

The revolutionary impeller design works by accelerating the air within the fan evenly, over a substantially longer distance than with standard axial fans.

The kicker for everyone looking at the snazzy picture of the impeller over to the left may be that it rotates counter-clockwise (backwards) - totally opposite to that of traditional axial fans.

The grey bar above the picture of Verax fan on the left is meant to illustrate the amount of useable surface area for drawing in air. Conversely, on the right hand side we can see a typical axial fan cross section and the lower amount of useable surface area it has for drawing in air.

Verax GmbH make a really quiet heatsink, but one that we'll have to test out before we can really tell how well it performs. When we first tested this heatsink we were in for a pretty big shock just because it was so quiet. Unless you literally put your ear next to the variable temperature controlled fan, it is nearly impossible to hear the unit. Of course, rotating at 1600RPM-3100RPM means that airflow may not be what all of us are used to, but for those systems which require absolute silence the Verax P14 offers up a very real solution.

The fans themselves are used in powersupples where I think they might actually be better suited. Retailing for about $59 USD this heatsink can be picked up from Veraxfans.com. The Verax P14 is a sizeable investment for a heatsink given the overall design of the pure extruded heatsink.

    The fan is pretty strange in its design since we've yet to see anything which even remotely resembles the unit. Overall though, a fancy design won't always get your computer running cooler. With the onslaught of small formfactor PC's and VIA's EDEN motherboards a noiseless fan such as this could fill out the role of home entertainment system, or MP3 player quite well.

    Additionally, since the fan is just the right size for a powersupply, it might be useful there where it can serve as a less noisy fan for cooling the internal electronics. In this task the verax fans might just ultimately be suited best for. Given that the internal thermistor which measures temperature and consequently adjusts fan speed is located in a small recess in one of the motor braces. That location makes it ideal for tracking the input air temperature and pretty bad at adjusting to the temperature of the actual heatsink.

    For our tests we had to make a small adjustment to the placement of this internal thermistor in order to get some respectable performance out of the Verax P14. Prior to this very minor and very simple adjustment the fans were stuck at a lower rotational speed which resulted in temperatures on the 100W test platform in excess of 107 degrees Celsius. To make the fan react to the actual temperature of the heatsink we moved the thermistor out from its location and bent it is so that it would be in contact with the tips of the aluminum heatsink fins.
