Cheater - ducted PC fan for Noctua A12x25

Hello everyone,

this is Cheater. Ducted fan designed for competition in 3rd season of a youtube show Fan_Showdown on the channel Major_Hardware.

Cheater is built around three basic ideas:

1. Exploit the rules of the competition and think outside of the fan shroud.
2. Ensure the largest possible area of the cooler to be exposed to moving air ("diffuser").
3. Play with aerodynamics with velocity stack ("splitter"), progressive pitch aerofoil blades and nose cone.

Well I have to admit the fan itself is not the best, it's too heavy (hints the lower RPMs) and complexity makes it hard to balance. But you can see what the ducting did at the show, Oooweee!

No supports needed.

Thank you to Major_Hardware for using it in his show!

PS: No RGB included, sorry.

EDIT: I added T30 variant too. But please keep in mind that inner diameter is made for specific Major Hardware cut fan hub, so it might not work for you without some fitting.
