Pros: Controls three fans. Has very long cables and a control module that can be stuck just about anywhere. You can control the fans from the front or the back of the case using either a 3.5 bay controller or the expansion slot controller. Really helped get my noise level down from a bunch of 80mm fans, and I can easily turn them back up if it gets hot in the case.

Cons: The knobs on the 3.5 control are HUGE, and wouldn't close in my tower case. Thankfully the 3.5 bay had some mounting points farther back, so I used those.

Overall Review: It is a well constructed item, and really gives you some control. It's also relatively cheap and simple. I might see if i can find some smaller knobs.

Pros: Silverstone products always seem high quality. I have one of their external enclosures and I like the aluminum design. This product is no different. It reduces fan speed and the cables are nice and long. I really like how it gives you the extra rear bracket if you only have one external 3.5" bay that's already filled.

Cons: I have a minor issue with it delivering the full 12V. I don't think the adjusting knobs are calibrated right because the fans do not spin at their full speed when the knobs are turned all the way up. If you remove the cable going to the control knob and leave the fan plugged in, the fan starts spinning at full speed. So unless my 12V rated fans are pulling more than 12V to start with, I assume that it's a problem with the controller.

Overall Review: I doesn't seem like a big problem because most of us in the market for a fan controller want to slow our loud fans down a little. I still find myself turning down the knob from full to get my desired sound level so this isn't really a problem for me. I believe it could be for others, though.

Pros: Fits a 3.5 inch slot, plenty of cable length running from chassis with the knobs to the controller itself. Supports up to 3 fans.

Cons: Very poor build quality, had mine die after less then 3 months of ownership. Two of the plugs on the controller pad which mounts to your case died out, leaving only one fan spinning. Better off buying molex repeaters if you need to connect multiple fans and only have one or two fan connectors on your motherboard. Knob adjustment doesn't seem to be all that great, even with my 1200 RPM Fractal case fans.

Overall Review: Silverstone seems to like overpricing their products and this one is no exception. Better off getting a Scythe controller even if it costs more money, the build quality of this product is just not worth it in terms of durability and lifespan.

Pros: Works and seems well made.

Cons: The knobs are backwards when I adjust the fan speed. It says on the face H and L for low and high but when I turn to H it goes low. It's no big deal since I know how to adjust the knobs. It's thinner than I would of liked. You will need a 3.5 to 5.25 bracket to mount this...since it's not included.

Overall Review: It works fine but they should of mounted the knobs the oppisite way to go with the face plate. The board it comes with is pretty soild and has a 3m sticker on back and is guarded with plastic to protect it. You don't even need to use the board if your fan has a built in connector for the controller like my silverstone FM121 fans. You can swap the knobs off of this if you wanted by pulling them simply off.

Pros: Fits nicely inside the case. Despite what some might say, I can easily fit this in the case, with no interference from other cables or the like. It looks nice and seems to be a pretty simple design.

Cons: Not a fan of the converter-thing (I'm not technically savvy on this, but it looks like resistors). It doesn't stay in the little plastic square it comes in. Sure it's glued in, but it pops out pretty easily. At first I did nothing, but of course (my fault, again) I didn't take into account the exposed metal on the bottom of the thing. It sparked once when it came into contact with the case. I just covered the bottom in electrical tape and boom-done.

Overall Review: I like it a lot, and think it's pretty good. Seeing as the jumble of resistors wasn't glued down too securely, it could have been designed more securely? Honestly, I just wasn't too gentle on the poor thing, so if you treat it well and be careful to not yank on the cables, there will be no problems. I absolutely recommend this product.

Pros: Controls the speed of the fans directly if your fans have 2-pin speed control connectors, like the TT A20XX series fans, without dimming the LEDs at slow speeds. If you've got these types of fans, it comes with a PCI bracket that holds 3 extra dials and can control 3 other fans too.

Cons: Tough fit into my Silverstone TJ-05 case. Even with drive bay sliders, the sides scraped the inside of the drive bay rails. Nobody is going to see it, so no big deal. Maybe if Silverstone reduced the width of the unit by .25mm on each side it would be a better fit for their case. Paint finish on the 3.5" unit is a flat black, seems like it will be prone to scratches. A fingernail could take the paint off. Tough to close the case door since the knobs protrude 5/8".

Overall Review: This unit is great when paired with TT smart fans. I have 3 80mm and 3 120mm TT fans in my Silverstone TJ-05 case. This package controls them all. Since the TT fans have 2-pin speed control connectors, they can connect directly to this controller. The package also contains a 3-knob PCI bracket controller with 3 2-pin speed control cables. This is in addition to the 3 on the front 3.5" drive bay module. This Silverstone unit works exactly the same way the TT PCI bracket controllers did that came with the fans. I've had the Za1man MFC-1 Plus and the TT XController, and neither controlled the fans' speed directly as this one does. Happy customer.

Pros: It has long cables and fits nice and neat in a 3 1/2 bay.

Cons: I'm using this controller to control 2 "FM" series fans and one standard 3 pin connector case fan. For some reason when the knobs are turned toward the "L" side the speed increases and of course the "H" direction gives a decrease in fan speed-- DOH!!! I assumed that "L" was meant to stand for "Low" and "H" for "High", but maybe I got the Latin version where "L" means fast or something... I double checked all connections and can find no other way to hook it all up. In any event it DOES control the fan speed.

Overall Review: The rear slot controller is a nice lil' extra.

Pros: choice between front panel or rear expansion slot. I actually removed one of the rheostats from the rear slot and mounted it straight to the back of my case; I only needed one.

Cons: PCB is indeed cramped, but mine wasn't flimsy. Wish I had 2 PCB's or I could just buy the PCB separate, but then it would be like getting two controllers instead of one.

Overall Review: Yes the cables are quite long but I see it this way: Better long than short. I'd much rather have to tie/wrap up long cables than to be stretching them or forced to move the PCB from where I want to put it. Plus long cables help with cable management sometimes.
