After my recent upgrade (RoBo3D R1) to the E3D V5 hotend, I have now received my E3D V6 today (I ordered only Tuesday this week, and although the lead time for the V6 was supposed to be a week, it shipped the same day, and was delivered today, this Friday morning, in only 3 days, from UK to the Philippines! Wow!). However, there's some confusion about the fan: In Tom's review of the V6, at around 1:00 in, he states: "... the V6 also comes with the updated and quieter seven-blade fan instead of the noisy five-blade one that came with the early V5 hotends." Now... In my case, the V5 (ordered and delivered mid-May) already came with a 7-blade fan. However, the V6 that I received today comes with a 5-blade fan. The labels on both fans are exactly the same: "RD3010B12H, DC12V, 0.08A, Two Ball" So... Is this just a shipping mistake? Or did Tom get it backwards? Should I keep the 7-blade fan (already wired up with my RoBo3D), or switch it for the new 5-blade fan?
