Some fan splitters come with additional power connectors to connect directly to the power supply unit (PSU) for better power delivery. That said, the mesh braiding is a little bit tougher, with a tighter weave with no visible gaps. It’s also reinforced near the tips, with rubber banding to keep anything from fraying. But a 3-pin fan has to draw a minimum of 5 volts at all times. If the current drops below that, the fan motor will die. So on an idling PC, you’ll be wasting power. A PWM fan, by comparison, can run at extremely slow speeds. Not only will this save power, but it reduces wear and tear on your fan. Before we finish, let’s take a minute to discuss what a PWM fan is, compared to a traditional 3-pin fan. A traditional 3-pin fan is controlled by the motherboard or fan controller by adjusting the voltage. They can draw between 5 and 12 volts, depending on the system’s needs. A 5-volt current will cause the fan to run slower. The more current is supplied, the faster the fan will spin and the more cooling it will provide. The best part is that it doesn’t really alter the fans’ power difference, and there is also no loss in the RPM in most cases.
If aesthetics matter to you, consider selecting a fan splitter that matches the color scheme of your PC build. In most cases, this works very well. The fans run at a moderate speed most of the time, and speed up when the system is under a load. However, newer PWM fan controllers can slow your fans down even further when the system is idle. This is an excellent power saving feature. So what do you do if you want to use PWM technology or add additional fans to your build? You use a splitter cable.

The Cable Matters splitter can support a maximum of 36 watts, or 12 watts per fan. That might not sound like much, but computer fans don’t draw that much power. If a fan draws two watts, that’s an unusually high power demand. PC fan splitters are basically cables used to connect the PC case fans to a single fan header in a motherboard. It attaches three fans on a single board header and allows you to have other fans in your system to improve the rig’s airflow. Third on our list was the RISHTEN Fan Splitter Hub. This hub is unique in a couple of ways. To begin with, you can connect up to five fans, which is more than any of the others. For another thing, one of these connections is for your CPU fan, which can simplify your wiring. Finally, it’s a flat hub that can adhere to the inside of your case. In a transparent case, this looks sharper than a basic splitter. Consider the warranty period offered by the manufacturer to ensure you're protected against any defects or malfunctions.
Additionally, select a fan splitter that supports low-noise fan connectors for quieter overall operation. Opt for a fan splitter with cables long enough to easily reach your fans without causing strain or cable clutter. The wires themselves are covered with a set of nylon mesh sleeves. These sleeves do a good job of protecting the inner wires, while still allowing plenty of flexibility. You might think that PWM fans are designed to improve PC performance, but that’s not the case. In fact, a 3-pin fan is every bit as good at cooling your PC as a PWM fan. Instead, PWM fans are designed to improve power efficiency when your system is idling. In this situation, your PC doesn’t need nearly as much cooling as it normally does.

Your fan is one of the most important parts of your computer. While PC fans are small and inexpensive, they’re essential for keeping your system cool. Neglect them – or fail to install enough fans – and you could damage your computer. Your fans are wired into your motherboard or fan controller, which controls the speed by adjusting the voltage. When selecting a PC case fan splitter, consider the size of your fans and the number of fans you plan to connect to the splitter.
The Cable Matters PWM Fan Splitter Cable is a simple three-way splitter. There’s a 4-pin connection at the base, with three 12-inch wires protruding from it. Each is tipped with a 3-pin connector, which can plug into a 3-pin or 4-pin fan. Keep in mind that the speed pin only works on the main connector. In other words, all three fans will run at the same speed, be that fast or slow.
The Overclockers Difference
The price is moderate, which I feel won’t be an issue for you. Moreover, as a splitter cable, it’s a decent option for hooking up multiple fans.
