DreamWare Computers posted a review on the Lamptron FC4 Fan Controller

Although there are plenty of great temperature/PWN controlled fans on the market, sometimes the best way to achieve the cooling to noise ratio you want is to simply do things manually. When it comes to manually adjusting fans there is a huge plethora of great fan controllers on the market to conquer the task. The easiest way to narrow them down is by figuring out how many fans you need to control, whether you'll be running more than just fans with it, and of course the looks will likely play a huge factor too. We've seen some cool fan controllers and bay-busses here in the past from Lamptron so I was delighted when the opportunity came up to review their latest FC4 fan controller.
