I have the v3 black and the stock fan is great, but i don't know what the name on it is, i may want to get more. i would take it out and look at it but its in a hard spot.
I'm sure they are using one of their own fans but it does not give a part number for the fan under the specs for the V3 case, only the type and details of the rear exhaust fan- Rear (Exhaust) : 120 x 120 x 25 mm Blue LED fan, 1300rpm, 17dBA. You should be able to look through their fans and match the fan specs.
