Rabi PWM Fan Hub, PC CPU Cooling 4 PIN/3PIN Fan Power Cable Hub Splitter Adapter Sleeved PWM Case Fan Splitter for 12V Desktop Computer Cooler Case Fans 15 Inch (5 Way)

Small enough to hide in the back of the spaghetti junction. Works out the box, zero set up needed and can be stuck to a surface for better cable control if that's what you desire.

I wasnt sure if this little device would work or even handle my Noctua/corsair fans but thankfully i was wrong and it works a charm. very easy install and now my 3 fans are all hooked up!

Cheap and works well 3 x 120mm 12v noctua fans from one port. Quite small and the sticky is keeping this thing attached still.

This item is ok and plugs into the main cpu fan header. the other fans then plug into the other prongs on the item. It does not allow for 3 pin software control only simply constant fan speed. I do not know if you get fan control with 4 pin fans, as I am using three-pin only. All said the device works fine and as expected. I would recommend if you just want an extension to fans.

I only have two chassis fan headers on my motherboard but want to use a six fan set-up - 3 intake (front) and 3 exhaust (1 rear, 2 top). Bought two of these. 1 for intake and 1 for exhaust. They work brilliantly. I initially didn't plug anything into the CPU fan slot on the splitters but after checking ASUS Fan Expert 4 I realised I couldn't see any of the fan RPMs so I moved one of the fans into the CPU slot and then they all appeared fine. You can't control them individually (at least I don't know how to) but I don't really need to - I simply wanted all the fans working intake (or exhaust) to work at the same rate - so it wasn't an issue for me.

Very good for price easy to fit my only dislike is the sticky adhesive pad on the back only stuck for about a day but very easy to sort with a very little drop of glue

This is really good for the price but mine unfortunately came with a few bent pins, they can be bent back somewhat but not as good as they should be, they should have some foam on the pins to protect them in transit, other than that it's sticky pad is pretty good and it's sleeved cable is a very nice touch for the price.

Finally got round to installing additional fans in PC, and hit very quickly a lack of fan connectors on the motherboard. This was a quick and simple solution. The unit attached the the inside of the case, in an out of the way area, with no problems. Been running since installation, with no power issues/glitches... Would buy again for other PCs if/when needed.
