SilverStone PWM Fan Hub System Cables, Black (CPF04)

Works perfectly! Plugged the PWM fan header into a designated PWM fan header on the motherboard and set the fan mode to "SILENT" within the BIOS (you can set a higher, more aggressive fan curve if you want), and plugged the SATA power supply to the SATA power lead off the power supply and plugged the three fans into the fan hub. Fans immediately sync up and run at low PWM speeds. Unit is definitely an effective solution for management of multiple 4-pin and 3-pin fans. You can combine both 4-pin PWM fans and 3-pin voltage fans together. The only catch is that you have to use at least one 4-pin PWM fan and plug it into the port that has the glossy look to it with a slight bevel in the plastic that identifies it as the master fan port. You can then plug any kind of fan into the remaining ports and they will slave to whatever PWM signal is sent from the motherboard PWM fan header to the hub itself. Also, make note that most motherboards have multiple 4-pin fan headers, but in actuality only a few of them are PWM compliant. I found this out the hard way and it took me a bit of troubleshooting to find out that there were only 2 4-pin fan headers out of the six 4-pin fan headers on my particular mother that properly supported PWM; the CPU_FAN fan header, and the CPU_OPT fan header. Motherboards vary, so make sure to test the CPU and System fan headers first. the "CHA" and "OPT" labeled fans normally due not support PWM and when you try to use them. They are actually voltage regulated. If you try to use them, the fans will run at full blast 100% speeds.Good luck with this product and let me know if you have any questions!

I like this product a lot, it can split one fan port into 8 and does not draw any power from your motherboard. It also does this while looking sleek, in case you need to put it somewhere visible inside your case. It does not feel cheap but it also doesn't feel like it is of the highest quality.It draws power from a SATA plug. It connects the speed control from the 4th pin on the motherboard to all 8 fans, and it connects the RPM info from the fan plugged into its glossy looking port to the 3rd pin on the motherboard. It does not connect to the power or ground pin on the motherboard's 4-pin fan connector. You can use it without plugging it into your motherboard but your fans may run at 100% all the time time whereas mine run around 40% most of the time, and boy are they quiet!!! It's really nice to be able to use the fan speed control for so many fans, my case has 6 140mm Be Quiet! Silentwings PWM fans.If you have fans of different sizes, like say you have 3 140mm fans and 1 120mm fans, I would recommend plugging the single 120mm fan directly into your MB and plug the 140mm fans into a hub like this. This way your MB can see the speed of each size fans. Not sure if it matters too much or not, but I notice in another computer I have that the 140mm fans spin at ~550RPM and the 120mm fans spin at ~1,200RPM when they're both set to 40% power.I'm glad this uses a SATA power port instead of an IDE power port. I finally have a PC build free of IDE power connections :)

Absolutely great. This saves me the hassle of getting my hand in the PC trying to plug those tiny pins which take forever, and when they do, There is ugly wires all over the motherboard which sucks because I have a windowed case. The fan hub itself is powered through SATA connector from my powersupply which is PERFECT because I had 3 extra SATA connectors laying around the back of my PC. Simply connect it to the SATA connector from the Power Supply and then plug the other pin into the motherboard so you can control the PWM fans. Then plug the fans into the actual hub. Also, it holds 8 fans, which is more than enough for most people. The max amount of fans my case can hold is only 4. Unfortunately, two of my fans are not PWM, so I can't control them from the hub, so the hub automatically sets it to full speed, I believe. It's kinda noisy, but I can live with it. If you have a PWM fan, that isn't a problem for you. Overall, the product is great for cable management and just helpful. It's also the cheapest fan hub I've seen on Amazon. Cheaper than NZXT, Phanteks, and other fan hubs. The only con is you can't see that cool Silverstone logo since it will be in the back of your PC.

I got the 8 way fan hub and it works well. I have been using it to give a little more control over my 3-pin fans by having one fan 4-pin as a control.The only problem is that you can't shut the fans off completely. With just the 4 pin fan plugged directly into the motherboard, I can shut it off completely through software. With the fan hub, even if just the 4-pin is plugged in, it appears that it can't go below ~25-50% speed(Hard to tell exactly where it stops slowing down). That's not a big deal but each of my fans can run silently if you lower the speed enough. Where it is at, there is a constant hum.I guess I could just get a fan controller, but I like having my computer be able to turn up the fans if it's getting toasty. Overall I am happy with the fan hub, just not thrilled.
