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'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

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.

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.

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!

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.

Been a great accessory for PC building. I've used these 3 times and keep extras for future projects. Works great when there's only one fan header or daisy chaining isn't an option. Strong adhesive on sticky pad and small footprint so it can fit almost anywhere in a case.

Works well for my PC. Convenient. Good length. Good quality.

It's a great hub for my cooling fans. Very easy to use, the length is decent and the size is great.

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

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.

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.

Didn't fit the CPU fan adapter well.

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