PWM Fan Hub, PC CPU Cooling Extension Cable Hub Splitter Adapter Sleeved Case for 12V Desktop Computer Cooler Fans 1 to 5 Way (15.7 Inch)

I recently installed the ThreeBulls PWM fan hub to connect multiple case fans in my PC and it works really well. It lets me run up to five fans from one motherboard header without any power issues. The cables are nicely sleeved and the build quality feels solid. Setup was easy and I did not need extra adapters or splitters. The PWM control works as expected and the fans adjust speed based on temperature with no flickering. Everything stayed neat and tidy with the included cable ties. The only minor thing is the hub is a bit longer than expected so I had to find space behind my motherboard tray. It did fit in the end and does not interfere with any components. Overall I am very happy with this hub. It is reliable, well made, and makes managing multiple fans simple. I would buy it again and recommend it to anyone looking to improve airflow in their PC.

The fan hub works well and performs exactly as intended. Installation was quick and straightforward, and it made extending and organising my fan connections inside the case much easier. The sleeved cables feel good quality and connect securely, and it has been working reliably for a while now.

The quality of this is okay as it is as seen in the picture it’s just a cheap fan hub. It looks fine but you can hide it from sight if you fit it in the right place. It works well however one of the pins were bent. I’m not sure if it was bent beforehand or not but I straightened it and it worked just fine.

Accepts 3 and 4 pin and solves the issues of connecting multiple fans to your motherboard with limited headers. It also has double-sided cushioned tape so it can be securely stuck to the inside of case wherever you like (out of sight preferably!) and without risk of movement. It works perfectly for me on a mini ITX board limited to three headers (CPU, FAN1 and FAN2) but with 6 case fans and AIO. A couple of things to mention: 1) the design seems to infer that you should plug your CPU fan into the splitter, and the splitter into the CPU header. You don't have to do this of course. I use my motherboard CPU header for my CPU cooler, the other fans connect to this splitter, one of the free fan headers, and are then are easily controlled from the bios setting for that fan header. 2) any fans connected to this cannot be individually controlled for speed or voltage. This seems obvious but is an easy mistake to make. If you require variable speeds for your fans, don't connect them all to this splitter. Yes, it's cheap and ugly and the solder points will be a weak spot, but just don't pull on the connectors or wires. Can't really go wrong for the price.

Working now for the past 10 months or so without issue.

Did what was required

Arrived in a plastic bag, no thrills, but was very easy to setup. Has a sticky back to stick onto the PC case. I plugged three case fans onto this and each fan turns on and off three times, probably to ensure it's working as intended, before running at the same speed on all fans. No visible downgrade. Only thing I will say is the BIOS reports the fans as 0 RPM, but that's most probably because there's multiple fans connected and the 4-pin connector doesn't connect directly to a single fan, but it works as intended, and for 6 pounds, I couldn't complain.

one was bent rest work

I picked up this ThreeBulls PWM Fan Hub for my ITX build and it does the job. Right now, I’m running three fans off it—two in the front and the top exhaust—and it’s working fine. Just a heads-up: make sure your fan cables are long enough, especially if you’re building in a tight case like an SG13. I had to get some extension cables because things got unplugged when I put the case back together. At one point, I actually stripped a fan connector and had to swap out the fan, but after that, no issues. The cord length was perfect for my ITX build. This splitter isn’t powered, so I wouldn’t run more than three fans off it. Four might be pushing it and could stress your motherboard header. For what it is, though, it’s great for squeezing in extra cooling on a small build. It comes with a sticky pad so you can mount it wherever you need I have mine stuck in the back corner of my case and it hasn’t budged. Build quality is decent. It’s just a basic splitter, nothing fancy, but it gets the job done. If you’re working in a small case and want to add more fans, this is definitely worth picking up. I might grab another one if I need to add more fans down the line.

It will be very helpful if you have a lack of sys fan header and i like it because it’s very simple and you can install 4 fans

Works as described

Didn't fit the CPU fan adapter well.

It’s still new but it’s a slim design that works and is cheap. It gave me enough length to finish plugging in my side case fans with decent cable management.
