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: I installed this in a Cooler Master N300 case in the floppy drive slot on a new-build, I hadn't even bought my motherboard, processor or anything yet, I just had it running to bleed the air out of a watercooling loop and just to run the fans off an old PSU, within 3 weeks of turning the PSU on in the morning and off at night, it failed all of a sudden on fan control 1, 2 and 3 (left to right) and now only controls on number 4.
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.
