GELRHONR Chassis Fan Hub, SATA 1 to 8 Way12V 3 PIN Cooling Fan Splitter Controller Hub 3 Pin PWM for PC Desktop Computer Motherboard(12V 3-Pin)

I bought this controller because it was very inexpensive, and gave me an easy way to transition from 4 chassis fans to a free SATA connector as a 12 volt power source. The original fans in the server box had the cheap Molex 12 V connectors, and were quite noisy.I replaced the fans with some much quieter units that came with 3-pin connectors. The motherboard only had one of these, so I needed a way to fan out (pun intended) to 4 units. So this fan hub fit the bill for me exactly.I like the ON-OFF-LOW switch design. It's simple and it works. The hub also came with a pre-applied sticky foam base. so "installation" was simple peel and stick the board where I wanted it. Done!It's been in use for under a week, so I can't comment on its long-term durability, but I'm very pleased with it so far. It's simple and does the job it claims to do. I'd certainly buy it again!

This unit works great and is the natural evolution of this same device that uses an accursed 4-pin Molex power input. If you are using all 3-pin CPU fans, you will be able to put 8 fans on the controller, no problem.But the connector on 4-pin fans, being wider than 3-pin, extends over into the space that the connector next to it would occupy. In other words, 4-pin fans will fit and work fine, but you will have to leave the connector next to it empty. You can get five, 4-pin fans on this adapter and it works great.One thing you do have to watch out for is the sticky pad coming loose. This is not a problem unique to this brand or model. Every one of these kind of fan controllers has the same limiting factor.Over time, the pad will likely come loose from the back of the controller circuit board. This is a problem because then the metal contacts on the back of the controller are exposed and if it touches your computer case, things will short out. The fix for this is to also use a zip tie around the controller to physically bind it to the surface it's mounted on. You may have to drill two small holes for the zip tie. This is really not a big deal and guarantees that the controller will never short out against the case or other metal component.This little device is one of those things that if you need it, you need it, and you have to work around it's shortcomings. Still highly recommended though because it just works.

It is exactly what it says it is. SATA powered fan hub allowing 3 pin (or 4 pin) connectors to run off of your PSU directly instead of from a motherboard fan header. I got the 4000d airflow case from Corsair, but the fan in on my old prebuilt did not have 3 or 4 pin connectors as it ran straight from sata, so this was needed to power the 2 fans it came with. It has 3M tape on the back allowing you to fix it to the back of the case. The switch works exactly as expected low/off/high. I keep mine on high as the fans it’s powering are in the front so I want as much fresh air blowing into the case.*YOU CANNOT ADJUST FAN CURVES FROM BIOS OR AN APPLICATION!*IF YOU NEED something to power 3/4pin fan connectors, and aren’t too worried about needing to control fans from BIOS or applications, this is a fantastic option.

Good qualitg for what it is althought the fitment on the sata power was really tight had to put a verrrrrrrrry small amount of dieletric grease on it to be able to slide the sata power on. Works great.

Works really well. I’m a first time pc owner. Built mine myself. Really easy to put together. Uses sata connector to psu.

Great when it works, but it's faulty. Often times the PC will not turn on when this is plugged in. I have to unplug it, reset my PSU, turn the PC on, then plug it back in. Flipping the switch and changing the speed while the PC is on can also cause it to immediately short and power off my whole PC. My PSU is nowhere near power limits and the PCB isn't touching anything that would short it, so I have to assume it's the board itself. Saw a few other reviews noting this behavior but assumed it was rare. Going to stop using it rather than risk damaging my PSU.

This little thing is pretty cool. Hooked up my front 3 fans and set it to max. Its been holding up well, Be careful with the metal pins they get bent really easy.Plugged it in with no troubles.

The actual electronic components are perfectly fine and I actually prefer them over the more expensive options out there. The adhesive parts are atrocious. If you plan to mount this vertically, bring your superglue. I had to superglue the PCB to the top of the adhesive pad, then a week later had to super glue the adhesive pad to the frame. This particular application went on a test bench, so I wasn't worried about prying it off later.
