OCC has published a review on the BitFenix Recon and BitFenix Hydra Pro Fan Controller

Both of these fan controllers do their job. They both look great, are built with clear attention to detail, and will easily stand up to daily use for a very long time. If you have noisy fans or would like the ability to use noisy fans without having to deal with their obnoxious droning whenever your computer is on you won't be disappointed in either of these BitFenix offerings. The software for the Recon is a bit rough around the edges but serves its purpose, and the Hydra Pro is simple and effective. For the asking price of $39.99 for the Recon and $34.99 for the Hydra Pro, I really cannot find any serious faults in either product. Personally I love the automatic control on the Recon, and it will be staying in my own rig permanently!
