Summary: Supports 4 fans. Fits a 3.5 drive bay. Does the job without any issues. One thing I really liked about it is that it's modular, so if you only want 1 or 2 fans connected, you don't have to find somewhere to stash away extra cables. No LCD display or anything fancy, if all you want is a simple fan controller then this would be it.
Summary: Very easy to install. I have four fans in an msi micro atx case which was very loud at maximum speed, and for a long time now which was so annoying. The Q-fan (Quiet-fan) setting in the Asus motherboard bios settings is shadowed out now for some reason, maybe due to updating the bios or just blown? It did work when I first bought the main board, but now it does not work in software or bios for some reason.
Summary: Nice looking controller that fits perfectly with my case. Comes with 4 labelled fan cable extensions. I always like Scythe products as they are well made and work well. The actual dials themselves are very smooth and have a nice range from very low to max speed.
Summary: OK so when I brought this I actually wasn't paying attention and was expecting a 5.25" fanbus, so I was a little shocked when it arrived and was designed to fit in a 3.5" floppy bay. Luckily my new case had such a slot, and since I had no floppy drive to put into it this fanbus was fitted instead. And I have to say it is a pretty nice piece of kit. It has no lights on it, so it doesn't draw attention to itself or distract you, and the knobs on it turn smoothly.
Summary: Looks well built and more importantly, does exactly what's required. Controls all my fans without issues and fitted into my hard drive bay nicely as i wanted it to be inside the case rather than on show. If you're even sneaky, can buy the 1.99 startech tx fan splitter cable on Amazon and run two fans off one plug/control. Ended up buying mine off ebay for cheaper from ADMI (yeah, go figure that!?
