Harmony Central have posted a video of Bryan showing the new Receptor v1.2 software and UniWire working (marvel as he unplugs and replugs the ethernet cable !!)

oh, about the fan, pretty quiet, I don't know about upgrading it so I'll let Rick answer that one.

The fact is, we designed Receptor for minimum acoustic noise for use in a studio. We measured different fans from different manufacturers in the vocal iso booth of Studio C, which has an ambient background noise level of just under 25dBA, far quieter than a typical studio control room. Extensive evaluations were also performed at our contract manufacturing firm using a variety of different fan and cooling apparatus designs.
The issue for Receptor is that it needs to be quiet in the studio, but also cool when it is on stage, which is a huge challenge. The slower the fan you use, the quieter the box, but also the less cooling, which results in a higher operating temperature. This can be a problem on stage, so that's why we recommend a fan change for live use where it will be used under hot lights or in full sunlight (i.e. festivals) by going to the modified Everflow fan.
Can the fans be changed by the end user? We need to officially recommend against it as this could compromise long term reliability.
We worked very closely with AMD to ensure proper thermal margin under a variety of operating conditions, and our selection of fans was done to minimize noise while maximizing cooling, so experimenting with cooling (or overclocking, for that matter) is grounds for voiding the warranty.
We've researched fans and cooling fairly extensively; the so called "silent" fans are really just reduced speed, i.e. they turn at 1800 or 2000 RPM instead of the typical 2700 or 3200 RPM, and of course the slower the fan the less air you move therefore the less cooling provided. We believe that we have reached a reasonable compromise between noise and cooling, and therefore recommend against modifications to the design.
