Product Description

The Swiftech 8-Way PWM Splitter connects up to 8 PWM devices (fans and/or pumps) to a single PWM fan conector on the motherboard, thus enabling speed-control of all connected PWM devices concurrently. We generally recommend to use the CPU_Fan connector of the motherboard,because most motherboard manufacturers usually allow a greater range of adjustments on this particular connector. PWM capable connectors must necessarily be 4-pin, but not all 4-pin motherboard connectors implement or enable the PWM signal modulation by default. Please carefully consult your motherboard documentation in this respect. Since only one RPM signal can be read by one motherboard connector, only channel 1 of the PWM splitter carries an RPM signal; thus the motherboard will only read the RPM signal of the PWM device that is connected to channel 1 of the splitter. The PWM signal cable has 2 wires: 1 for the PWM signal, and 1 for the RPM signal. Power to the PWM splitter is supplied by a SATA connector that must be connected to the Power supply.

5.0 out of 5 stars Good product, good price. A step above a Y splitter with a few minor caveats.
By Jeff on July 8, 2017
A step above a Y splitter. I wasn't completely happy with my last set of splitters because they had the tendency to slip out of the plugs while affixing wire ties, so I thought I'd give this a try.

It works great and can be mounted within the distance of the fan header you wish to use for monitoring and control. There are a few caveats you should be aware of, which I learned by trial and error.

The two first chassis headers I tried resulted in full speed only even though I could get controlled speeds on the same headers using a normal Y splitter. That was a bit confusing as I thought all the headers on my asus m5a99fx pro r2.0 were PWM capable. Finally, I was able to get speed control using the OPT CPU fan header. Thus, it appears of the 5 headers on the M5A99FX Pro 2 Motherboard only the CPU and OPT CPU headers works for this product - unless there's a way to reconfigure the other headers that I have not found.

Another caveat is I lose about 100-200 RPM's on my fans when set at full speed, not a big deal for me but just FYI. The identical fans connected to the same header as stand alone or split with a Y cable report higher RPM's then they do when connected to this fan hub. Now, I can't say whether it's actually lower RPM's or whether it's just being reported that way as I don't have another way to measure actual RPM's.

The mounting screws are nice, but I did not use. The double sided tape is nearly useless because it is too thin to fill the void of the uneven surfaces between the plastic product base and the surface you wish to mount it to. I recommend [[ASIN:B0083K36KA Scotch Outdoor Mounting Tape, 1-inch x 60-inches, Gray, 1-Roll (411P)]] and it works great. Strong enough to hold, yet you can still pry it off carefully with a little effort - I used it to mount a fan too - no problem.

The limitation of mounting is the distance from the header, so that I could accommodate 3 fans on two sides of my case I mounted it on the backside of the motherboard tray which works perfect, plus I can add any other case fans I wish to add later being near the case center.
