Verax GmbH P14 Silent Heatsink Review
  75%   
Abstract: The kicker may be that it rotates counter-clockwise (backwards) - totally opposite to that of traditional axial fans.

Okay there are few things to keep the numbers in perspective when you look at the above list of reference heatsinks. Yes, the performance of the Verax P14 is pretty... well... low. The spec sheets peg this cooler at AthlonXP 1900+ cooling levels but I would honestly be a bit hesitant to endorse that.

Where I think the Verax heatsink would be ideally suited is in the small form factor environment where both overclocking and high case temperatures are generally well controlled. On an Eden system the Verax P14 would be able to offer better than convection cooling at basically zero noise levels. But first, let's look at the final rise above ambient temperatures.

Okay, so the numbers tend to paint a pretty interesting picture here. Yes, thermal performance on the 100W test die is just within spec for the AthlonXP 1900+ whose maximum recommended thermal die temperature is 80degrees. Would we feel safe using the P14 on it? Probably not. However, the upside to this heatsink is that if you are willing to let your processor run at a higher temperature range (so long as crashing doesn't occur) you can actually get away with a practically silent actively cooled heatsink that doesn't take up much space.

Use on a VIA Eden processor is probably a hell of a lot more interesting though. The Eden can operate with just a passive heatsink but it does get a bit toasty after a while. The beauty of those systems is the very low noise factor, and it is here that I think the Verax P14, or even just the Verax fan would do really well to add a little extra cooling prowess.

By all accounts Verax have a very revolutionary design on their hands that does solve the low noise requirements of many consumers, but moving above that 50W test level brings the temperatures up to an area that is not comfortable for us, or most people. Using just the fan in a powersupply would be really advantageous as the level of cooling most 300W powersupplies typically need is not as extreme. Verax literature even mentions that because of the way the fan operates, it is a little better suited to the closed spaces of a powersupply.

So the bottom lines looks like this; use in a powersupply or on VIA's Eden processor (we're taking just the fan here) is a definite yes. Use of the Verax P14 on an Athlon XP makes us a bit worried, and so I'd have to say no, unless you are comfortable with your chip running at elevated temperatures to achieve the low noise gains.

If you think the Verax P14 is right for your zero-noise computing applications, you can pick up the heatsink from www.veraxfans.com for about $59 USD.
