🔌 ThreeBulls 2 Pack PWM Fan Splitter Cable, Sleeved Braided Adapter for Computer PC Fan Power Extension, 1 to 3 Converter for ATX Case Cooling Fan Cable, 10.6" 4-Pin/3-Pin Review

These splitters are very good for splitting 3 fans into one header. The only problem I had was one of the pins on the forked end came loose and wasn't connected to the fan. I managed to put it in place and fix it with glue. Since then it has worked flawlessly. Otherwise I had no problems.

I use them for 3-pin DC fans. I was planning on pulling out the 3rd pin (RPM sensor) on two heads but these guys thought ahead and only left it on one connector! In case you didn't know, when multiple fans send RPM data to the same line. , it turns off and you always read 0 rpm. They look great with braid and do the job well.

There are negative reviews here, only one is 4 pin and the other is 3 pin. That's right. The 4th pin is a signal wire that reports the fan speed. You cannot send 3 fan speed signals in one header. Therefore there is only one signal with one message per computer/header. Almost all splinters are like that. This is perfectly normal.

They worked great. I have confirmed that both splitters are working. The cables appear to be of decent quality with a nice jacket. As another handy reviewer before me said, only one of the 3 headers is 4-pin, but that's what you want to share 3 fans on the same motherboard with a 4-pin fan header. So only one fan interacts with the mainboard, the other two do the same. I tested this with the motherboard fan speed software; All three fans change speed at the same time. Works perfectly.

Excellent 4 & 3 pin fan splitter. This is for my 3 SP120 RGB Pro fans that came with the Corsair 220t case. My motherboard didn't have enough connectors so it was a great pickup. I initially didn't want to make this purchase because I figured these splitters wouldn't allow my motherboard to control fan speed since my fans are 3-pin and my fans would run at full speed, but they don't. If your motherboard is compatible with a 4/3 pin fan controller, these splitters will work fine. I previously…

As described these expanders work equally well with 3 and 4 pin fans. The 4-pin socket connects to a 3-pin or 4-pin socket on the motherboard. It is divided into three connector cables to which the fans are connected. Only one of the three has four wires going to four pins, the other two only have three pins and three wires. Wait! The? How can it work? Here is the answer. One pin, pin 3, is for the fan tachometer. This is true regardless of whether you are using a 3 or 4 pin fan. The RPM signal
