PWM Fan Hub, PC CPU Cooling 4 PIN/3PIN Power Fan Extension Cable Hub Splitter Adapter Sleeved Case for 12V Desktop Computer Cooler Fans 1 to 5 Way (15.7 Inch)

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

Didn't fit the CPU fan adapter well.

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.

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.

Works as described

It works as intended and runs great. If you are looking into this as a way to power a pump on an AIO, I HIGHLY suggest you do not buy or use this product for that. That being said, the adapter itself has 5 headers, allowing you to power 5 fans off 1 MB header. I personally would not recommend running more than 3-4 fans off this product, especially if you're new to building PC's. Note that the first header labeled " CPU " must be the first fan position when using this product. After the first 3 headers, the 4th and 5th will supply power, but will not run your fans at full power. If you have an experience like others on in the reviews of the product catching fire or so called " exploding " then you are either running too much power to the product or your MB cannot supply 5 fans on the product. As for the wiring itself, it's very well sleeved and protected. It's length however is rather short so definitely plan ahead on your fan placements and header locations on your motherboard. The sleeve on this product is very difficult to bend and manipulate, I suggest you only bend the cable at areas that are not directly near the header or the actual board itself, it felt fragile. I would recommend this product to anyone intending to add more than 5-10 fans within their build, just make sure to check your MB support.

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.
