Summary: I have owned two of these now for more than a year and they have worked well in several builds now. Read: I have plugged and unplugged these things with care and without failure many times. There is very little to fail on these units. There is no bright led to distract your eyes. No touch panels or readouts to fail. Low for silent surfing, high for gaming. There is a tendency for people to think that more complicated is better.
Pros: Simple, simple, simple. Does everything a fan controller should do.
Summary: Got this for my HTPC, which runs 2 80mm and 2 120mm fans. The two 80mm are on a single channel, and each 120mm has its' own. Luckily, i was able to mount it back a bit to allow my HTPC door to close, which still allowing access, but i guess that's a bonus to the case, and not this product. It'd be nice if there were clearly visible markings to tell you the knob positions, but that will e remedied with some silver marker and a template.
Pros: It works. Good feel to the knobs, High power tolerance.
Cons: hard to fit fingers to plug in fans and power, No OFF function., No marking for level.
Summary: What can I say, this fan controller does it's job and now I can chose at what speeds I want them to run at. The knobs do feel kind of cheap as if there about to fall off, but other then that it's pretty decent. It comes with lots of fan cables with enough length to get to the fans at the back of my HAF 922 case and the controller itself is fairly ascetically pleasing.
Pros: +controls fan speeds, +comes with cable extensions, +works
Summary: I needed a small fan controller to fit into a 3.5 inch bay and control a CPU fan, two scythe jyuni's and a 140mm exhaust fan. This controller does that fine, looks unassuming in the front of my case already dominated by a giant LED, and has next to no lag while controlling the fans. This controller will not shut your fans off, get a switch to turn them on and off, dont burn out controllers that can do it.
Pros: Its a fan controller, Stylish if you dont like alot of front case bling, Gets the job done, controlling fans!
Cons: Its not a bling fan controller, Knobs feel a little cheap
Summary: Purchased to control the fan on a Asus 9600GSO that came with a lousy aftermarket-style cooler with a non-variable speed GPU fan (no software control) that is unbearably loud all the time Had to bend two pins a tiny bit to get the very miniature 2wire fan connector to fit into the 3wire controller socket, but once I did it worked flawlessly, and gives me control over my case fans as well! (no more 5v mod for me!
Pros: looks rather sleek, matches my case
Cons: does not mount entirely flush with my case, recessed in between 1/8" and 1/16"
