Abstract: From the acoustic standpoint we have already established that the Verax fans are the quietest we have ever tested (on the order of 35dB).

Yes, the performance of the Verax P16 is pretty low, but acoustically it comes in on top. Where does that leave you, and where does it leave this heatsink? Well first of all, it should be obvious that this heatsink is designed not for overclockers, and not for your performance user, but for SFF PC's or people who have to have a computer run virtually silent. We'll go over all that in a second, so we might as well jump right into the rise above ambient temperature results...

With overall thermal results on this order it begs the question why we aren't effectively putting it on the Pariah list. The reason is this; Verax make this heatsink and fan combination for situations where noise levels are the deciding factor, and thermals second. The heatsink receives a moderate amount of airflow from the 80mm CAIRdB fan (estimate about 8-15CFM) at a very low velocity, and that is part of the reason why we see the hottest temperatures of all the reference heatsinks in this list.

Since there is a thermal envelope that all processors can safely run in, it is important to have a good case with plenty of passive ventilation so that the computers' thermal alarms aren't ever triggered. The Pentium 4 is a pretty forgiving chip when it comes to heat, and in small form factor PC's, or perhaps even a computer in a sound studio this level of quiet cooling is a welcome sight.

By all accounts Verax have a very revolutionary heatsink and fan design on their hands that does solve the low noise requirements of many consumers, but as processors move above closer to 80W things will get toasty. Remember, we are testing this heatsink at 50W and 100W, at it is only at the 100W level that temperatures begin to reach the tip of the thermal envelope. Personally speaking, I'd be much more comfortable using a Verax heatsink on a Pentium 4 where I know temperatures can go a little higher without fear of dead chips.

The fan technology is attention grabbing, but the price is a bit steep, even for German engineering. If you think the Verax P16 is right for your zero-noise computing applications, you can pick up the heatsink from www.veraxfans.com for about $69 USD - you won't find anything quieter, but make sure the high thermal range suits your applications.
