I had only two slots on the motherboard and I have 6 fans. It worked fine, although I only connected 3 3-pin fans. I don't use it at full speed.

No complaints, 7 months without any problems. It does its job and takes up little space, easy installation

Cheap and good little splitter if you have a problem with limited ports for motherboard fans.

It works great for having multiple 4-pin fans and running them at the same speed from the same header on the motherboard. I haven't tried it with 3-pin fans.

It is quite good, especially when you don't care if your computer reads all the connected fans or not. I installed one of the two fans of the processor cooler and it works great, but always at maximum speed (fortunately, the fans in my PC are completely silent, even at 80-90%)

I got it to connect 4-Pin PWM fans. Works great, all fans operate smoothly. Just to inform you, popular temperature monitoring programs read all the connected fans on this hub as one fan.

I have had the product for 8 months. I have connected 3 fans (3-pin) to a 4-pin on the motherboard and I adjust their speeds through software (simply all at the same speed). It works perfectly.

In the photo, it appears to be large, but it is not as big as a large lighter. It is useful and convenient, but in my opinion, it can only connect up to 2 fans for the 3-pin and 4-pin connection

Guys, I was influenced by the comments here and bought it... Well... The hub is only for 4-pin fans, but when you connect 3-pin fans to it, they operate at their maximum speed regardless of what is in the first port. It is misleading to say that it also works for 3-pin fans... So only the 4-pin ones work with the motherboard's PWM signal. Anything else can be connected, but it operates at maximum speed

Very useful especially for use with budget motherboards that come with only 2 fan headers. Detailed information about the connection and capabilities can be seen in the video I made: https://www.youtube.com/watch?v=K4D9YGxg2gI

It does what it says with fans with 2/3/4 cables. I am afraid of the fact that it does not have any other power supply, so the 4 fans are powered by the motherboard, but it also works with speed control. Everything is great

Very practical for Cable Management situations. You stick it wherever you want, it has 3M adhesive on the back, and overall it is very practical. It connects one cable to the motherboard and functions as a power strip essentially.

In a DS2H Gigabyte, all the fans are recognized and self-adjust individually one by one

Excellent, it does exactly the job it says. You can connect up to 4 fans on top. It looks very big in the photos, but in reality it is only as big as a medium-sized finger, extremely convenient size.

Exactly what the photos show, just small enough to fit in the back of the box. Much better than getting a splitter cable.
