Frequency generation means you can monitor the pump, just as you would a systems fan, via your BIOS software.
Flow is increased via a wider impeller and some small seal / motor changes.
New case offers improved internal temps, un-noticeable from outside.
Motor compartment is now not a permit seal, uses a gasket or o-ring which allows you to change the direction of the logo if you want.
Also in the future we will offer a "re-build" kit if needed, which the new case allows us to produce / offer to you cheaply (less then 12$ USD)
Also a couple of others details, I don't want to openly discuss right now

The claim comes from our motor sub-contractor, and it has been our experience that there claim is valid.
