novonest 1-to-7 PWM ​4PIN SATA PWM Fan Hub/Splitter for CPU Cooler Case Cooling Fan 4-Pin & 3-Pin Fans Cooling,FH07

Works flawlessly. PWM works perfectly to control fan speeds and is a sleek little box. The cables being integrated saves a lot of bulk so it’s a lot easier to cable manage than the units that use a separate sata cable. Having all the fan connections on one side is also a plus if you want to mount it on the edge of your case. Feels a little on the light side but seems to be sturdy enough. Would definitely recommend it👍🏽👍🏽

Works great no problems with product.....

Purchased to help with PWM case fan routing in my new gaming computer. I am running four case fans and this device made it dead simple to plug into the only connector on my motherboard. The bios is able to see the fans and I was able to setup a custom profile.The one drawback I was able to identify was the one-sided tape on the back. The tape itself is holding but definitely does not seem to be of the best quality. Time will tell how this holds up but the device should still function the same. For those of us with the metal cases... I would really like to see a version with a magnet backing.Definitely Recommend!Some of the parts in my build!SK hynix Gold S31 1TB SSD - https://amzn.to/343GjT5ASUS Prime B450M-A II AMD AM4 Motherboard - https://amzn.to/3ucQnE4AMD Ryzen 7 5700G 8-Core CPU - https://amzn.to/3AIn6SCCorsair Vengeance LPX 32GB (2X16GB) DDR4 RAM - https://amzn.to/3AWYAh3

I used this to control 6 noctua fans and then plugged the pwm controller into my corsair commander and now I can control all my fan speeds from icue easily.

Pros: Cheap, Works with 3 and 4 pin fansCons: While you can see the RPM for 3 pin fans, you can't control them, and they run at full blast. That is a major issue for fans that can run >=2000 rpms because your case will be really noisy.Thoughts: Though I initially gave this product review 2 stars because you can't control 3 pin fans, I am updating it to 3 stars. 3 stars is what I consider minimally acceptable for a product. Ultimately you CAN use voltage reducing fan cords, or buy fans that are slow at full blast. Had I known the limitation when I purchased the product I would have been able to plan accordingly or look for something else. The seller did update the listing after my purchase to reflect the issue, so new buyers are at least aware.

Does it’s job allowing to either match all case fans to cpu temp speeds, or just to have them for up to 7 fans.Has a wall grip on the back to place on your pc, wish I knew how to cable manage properly though 😅😂

This does EXACTLY what its advertised to be doing, despite some of the negative reviews. It doesn't allow you to individual address each fan but rather the cluster of them at the CPU header speed as long as they are 4 pin PWM fans. I had some cheap fan controller, that did its job but this looks nicer, mounted nicer and overall just FEELS better than the bare PCB one I had.Its only SEVEN fans, so if you have more fans, look elsewhere or add splitters (Though, I'm not versed in "electronic knowledge. As to what amps/watts is sufficiently supplied) My Noctua NF-A12x25s at the full speed of 2000rpms all run fine without a hitch, BIOS changes to the "CPU Fan" were recognized as I was changing my fan curve. For the price, can't beat it for quality and ease of use.No it will not allow you to control your 3 pin DC fans.

Looks nice in my case, was easy to mount and install, and now everything just works.
