PWM Fan Splitter 4 pin Adapter Cable Sleeved Braided Y Splitter for Desktop Computer CPU Fan Splitter PC 4 Pin Fan Extension Power Cable 1 to 4 Converter 10 inches (2 Pack)

Perfect! Had 0 issues with these and have been running them for years now!

I got four blue LED fans on my side panel of a Rosewill Thor V2 and this splitter got all four of them lit and moving air from the speed controller on the case. I probably had some trouble getting them to all work, but that was more blame of the speed controller cable than the splitter here

Worked great for the extra fans that I wanted to use, easy to install with no problems.

Appears to be decent quality. Initially I was quite thrown off by the fact that 3 of the 4 "split" (slave) ends only have 3 wires, but according to the other reviews, it appears the speed for these fans will be controlled along with the 4-pin end, so I'll assume it's ok for now. I'll come back and update this review if not though. Happy system upgrading out there, everyone and may 2021 go better than 2020!

I only use 2 headers on one and 3 on the other as my motherboard didn’t support all my fans native and other control are a little to pricey for a simple function these work perfect with no lose to speed on my fans 1600 rpm and they sit at 1580 range and 1590 range when I set them to full awesome buy!

I have purchased a lot of these and have pushed the lines very hard for over a year (with industrial Noctua fans) without any problems. These are useful for connecting fan controllers to x4 (or more) high-performance fans for liquid radiator or just air cooling. The lines are also thick, and not easy to accidentally cut. One note though, remember that it is for x4 fans and you may not want to run it directly from your MB if you have a lot of them.

These look great and do exact what they are supposed to. I have a polariz fan hub (36w per channel) so I use a 2-way splitter and from each of those I use these 4-way splitters to run 8 x Corsair ML140's. So I have 2 of my 3 hub channels running 8 fans each for my rads. These splitters work great and look great.

i bought 4 of these and after a month 3 fans stopped working, removed the splitter and plugged the fans directly to the controller, they got back working again, tested them again with cooler master splitter, they worked fine, so the quality of these cables is questionable.maybe its my luck as the other 3 splitters are still working fine.
