Well the problem is, the v1 was a prototype, it was never released from NDA, so im not sure why PPC's sold you a prototype model of the fan controller. It is likely that they were sent samples of the unit for testing. Again, still not sure why they were sold to consumers, the product wasn't even finished.
Sadly a pump did fail when I was using the v1 and because the RPM sensor didn't work I didn't know. No RPM sensor = no alarm. Lucky for me it was on my video card loop and I wasn't playing a game at the time. Windows blue screened... I rebooted and it didn't restart right. I looked over at my FC-5 v1 and saw my video water-in temp was at 125F. Luckily there was no damage to the video card and I replaced the pump.
Right now I am very happy with my new FC-5 v2.
