SilverStonePWM 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 :)

I'm so glad this exists.I have 6 big, beefy Noctua NF-A14 iPPC 3000 PWM fans which are 4-pin. They are very loud if you can't control them with 4-pin PWM. I tried the NZXT sentry 3, putting up with loud fan noise as its voltage control can only go to 60% ish, and it pulses up and down at that. Don't be fooled by this little contraption. It keeps my fans well-managed and well-powered, and it doesn't seem to get hot, even when the fans run at 100% (Which is like a jumbo jet's engines). If you're looking to individually control each fan, this is not for you, but frankly, I don't know what is. I don't know about you, but I haven't found any four pin PWM fan hubs that control each fan individually. So, this is the best bang for your buck. Sata cable provides plenty of power it seems, as I have 5 noctua fans each running at 0.55 amps and 12v which makes 33 amps. It sounds like a lot but I think the SATA cable has it under control with a total of 90 watts and 54 on the 12v rail (I think) and not to mention the capacitor that sits in the hub, correct me if I'm wrong. I am sure of one thing though and that is that this is worth it and you probably won't regret it as it comes in at the very reasonable price of 12 bucks. Buy it.

Looks like a great little fan hub. But it doesn't work for me. I have an ASUS Maximus VI Hero motherboard. When I plug 4-pin PWM Fans into this and plug the Silverstone into any of my 4-pin chassis fan headers (1, 2, or 3), all my fans only run at full speed. The Bios recognizes that a fan is attached and reads the RPMS, but the fan speeds do not respond to changes in the BIOS. ASUS Ai Suite also reports on the fan speed, but does not allow any changes, not fully recognizing that there's a fan attached. Based on what I've read now after the fact, it appears that in motherboards a little newer than mine have a SYS_FAN header to which this can be attached successfully. Or others attach to the CPU_FAN header. Since I run a Corsair Hydro and have those fans connected to the CPU_FAN header, I'm not going to try the Silverstone there. So I don't know if it's ASUS' fault or Silverstone's. This doesn't work for me. However...Pros: easy to set up, the wires are a bit long (but I'm a cable management fanatic), and at least for now the velcro feels sturdyI'll save it for the future, but for now, I guess I'm getting splitters and running the fans to the mobo headers.
