PWM Fan Hub PC 5 Way Splitter Sleeved PWM Fan Splitter Hub Adapter Cable for 12V Desktop Computer Cooler Case Fans 4-Pin & 3-Pin 14 inches (2 Pack) TeamProfitcom

My Silverstone MLOB case has four (three wire) 80mm ball bearing intake fans and exhaust is by my CPU heat sinks push pull pair of 120mm (4 wire pwm) fans. I plugged device into SYS Fan 2 (pull fan) and that 4 pin fan into the CPU port on the device, then connected two of my 80mm fans (in front of CPU, VRM). Worked instantly. I left the other 2 80mm SSD/HDD fans on 5V. Now I control 3 fans on SYS Fan 2 with Speedfan. It even displayse RPM speed for the fan on the CPU port. I tried a similar device, and it just didn't work (My variety of 3 & 4 pin fans or my mainboard maybe, IDK). I had also used a GRID but the software was fussy. And there is no room for a Sentry. This device works with 3 or 4 pin fans (2 AMP max I think). Great product, my CPU, GPU, SSD, and case have lower temps and quieter also. And I got two adhesive strips in case I need to relocate, thanks!

First of all it was a surprise to get 2 in one package. I didn’t need two so nice to have one for another project. I fitted this to a new Pc case a Corsair 220T, that already had a controller for lighting effects but my motherboard did not have enough pin outs(or plugs) to accommodate the number of rgb fans in the Pc. Buying this kept the look of cable management clean and organized.One thing i thought might be a concern was the adhesive. But now after having this in my Pc for several months I can confidently say the 3m adhesive is awesome. (I have no idea why the review mentioned to rate the noise level, there is literally zero)

I booted up my pc for the first time using these on the 4 pin fan headers on my motherboard, connecting 3 fans to each hub, but none of my case/ cpu fans seemed to power on. I assumed I had maybe connected something incorrectly. I double checked that everything was connected properly before I realized one of the hub wires looked worryingly loose at the part where it connected to the hub. I checked the other one (bought the two pack) and it was practically ripped open and split into two. I am currently stuck using my pc with a front 140mm fan that I’m unable to use due to me being short one fan header.UPDATE 9/4Was sent a new one from team profit although I already bought a pair of y splitters from a different seller (currently in my pc with 1 day shipping) in the time it took me to write the review for this one and get a response. Customer service deserves a solid 5/5 stars for its speed though. Will check the new product being shipped to me from teamprofit to see if it works and will change my review to a 5/5.

One of the cables died because the solder is too weak. They try to compensate with the 3m pad but obviously it was not effective. At least it came with two I guess. Just wasteful, though.

One worked and the other one did not work because the one tiny small wire was not connected to the 4 pin plastic piece, its weird cause it looks like its connected but if ya look closely you will see one last wire near the end not connected. FYI you have to plug this into the cpu fan header i tried to use my cpu opt fan header thinking it would work but it did not until i used the regular cpu fan header.
