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.

Literally no issues with this product at all. Comes with 2 adhesive strips (one on the product and 1 extra in case you get a new case or something). Its a 3M adhesive so it'll stick really well, just be sure to wipe down the area a bit with some rubbing alcohol or something. It feels sturdy, but the wire connections could maybe be done a bit better? Might didn't come off or anything, but just don't play around with it too much. The connector is a PWM connector and would fit on a motherboard, but I would actually recommend against doing so. Most motherboards have an average amp rating for 1 fan header at around 1 amp or so. Many non-LED fans will pull around 0.15 - 0.2 amps and some LED fans will pull a bit higher around 0.2 - 0.25 amps. If you do the math, having 5 fans at 0.25 amps running off a single 1 amp rated header will cause issues and COULD potentially fry your board. My recommendation is either; A) double check your user manual and see if your fan headers can handle a bit more power than most. I know some gigabyte motherboards are rated for around 1.5 amps. or B) do what I did and plug a molex to fan connector into it. If you wanted to adjust the speed of all the fans, just use one of the little resistor extension cables (that reduce RPMs) that come with most fans in between this product and the molex connector. All the fans will run at the same speed. Anyways though, good product and does everything it should.

It’s great for the motherboards that don’t have enough fan connectors it’s easy to use the look is great it works really well the size is beautiful there’s no noise it’s perfect

Works nicely. Cables fit nicely into every pin and now both of my case fans work.
