  • Solid Fan Splitter for Small Builds
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. ... show more

  • Small, cheap, and works. Small, cheap, and works.
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.

  • It works wonderfully and gets the job done.
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. ... show more

  • Great Fan Hub, But Hard to Hide
This fan hub does exactly what I needed—lets me add more fans to my PC without any issues. The build quality is solid, and the sleeved cables make everything look clean. Installation was easy, and all my fans are running perfectly. The only downside is that it’s a bit tricky to hide if you don’t want it visible through the glass panel. It would be nice if it had a more compact or low-profile design for easier cable management. Other than that, it’s a great product and does the job well! ... show more

  • It's good
It's been working pretty well, it's able to provide power to all the fans I'm not sure but when I connected the last fan it seems like it slowed everything down a little bit but overall it's a pretty good item if you only have one fan plug on your motherboard, it's small and has a sticky part on the back to fit wherever you like it looks pretty nice, if I had to say the power degrades the more fans you put but overall it's good for three at least ... show more

  • Easy way to add more fans
If you want to add more fans to your case and you don't have any more fan headers this is an easy solution. It allows you to link PWM fans unlike some of the splitters that don't have 4 wire PWM connections. It is good for connecting multiple fans to a single header to control fan speed without having to set up each individual fan from BIOS. Just use one setting for all the connected fans. Just be careful. Connecting 5 fans to one motherboard header might have to much amperage on one header. Usually you do not want to go over 1 amp per header. This means for a .3 amp fan you can only safely connect 3 fans to this hub. Check your mobo and fan specs to confirm. Most fan specs list the amperage per fan. It may be harder to find the specs on the mobo but I wouldn't go over 1 amp in that case to be safe. The only case I see connecting 5 fans would be 92mm fans that draw .12A each, you can safely connect 5 fans. If it is a .3A 120mm Corsair fan connect no more than 3 fans. Check your fan specs to be sure. Other than that it works great and has a nice braided 4 wire PWM cable with a decent length. A good part to buy a few extra and keep when they are needed. ... show more

  • For PWM to work properly - you have to have the one labeled "CPU" connected
Update: A recent update to the FanControl software enabled a new type of calibration that won't work with this adapter unless you have a fan plugged into the one labeled CPU. They really should rename them to FAN1-5 to avoid that problem. So as one other reviewer first mentioned - you have to have something plugged into the "CPU" fan for it to work right. Original Review: It's got the 4-pin PWM connector, but it's not PWM, it's DC. Works great with case fans where you just want them to all spin at the same speed. Where ever you plug it into the motherboard, just set the fan type to DC mode in BIOS. For Windows folk, you can use the FanControl software to either have the fans speed at a steady rate or set it to change based on a temperature source. I've got mine set to a steady 55% - and the system keeps cool and the fans are inaudible. Of course, depending on the fans you are using YMMV. Either way - very good result for the price. ... show more
