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. It is a Y-splitter fan cable. One end will be the SATA connection, and the other end will consist of fan connectors that are split in Y-shape. When I used it in my rig, it took less than five minutes to set up everything inside the PC case properly. No extra hassle was there. PWM, which is short for “Pulse Width Modulation,” and it works completely differently. Instead of receiving a variable voltage, the fan receives a 12-volt current at all times. However, the current isn’t delivered consistently. The computer sends out short pulses of power every few milliseconds. The closer the pulses are together, the faster the fan spins. The further apart they are, the slower the fan moves.
I feel the quality of materials used in the formation of this fan splitter is top-notch. That is why its build quality turns out to be excellent. Now, as for me, I was able to power 3 RGB fans with this fan splitter. In my rig, I tried the Corsair LL120 RGB fans. And the best part was, I didn’t require the Commander Pro. We’re about to review four of the best PWM fan splitter cables we were able to get our hands on. There are several features to look for on each one. If you want the basics, here’s what you need to know: So these are the seven best fan splitter cables that you can buy from the market. My list includes all types of options, so I think you don’t need to look at them anywhere else. These seven are enough to choose from and connect 4 pin or 3 pin fans or whatever you want. In my opinion, the Evercool DF001 is the most perfect choice to buy. But in case you want something affordable, you can go for the model from EKWB.The Winncon PWM Fan Splitter Cable 1 to 2 Converter has a similar design to the last one. There’s a 4-pin connector at the base, with 3-pin cables protruding from it. However, it only has two cables instead of one, and they’re a little bit shorter at just 10.6 inches each. 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. 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. If minimizing noise is a priority, look for a fan splitter that supports PWM (Pulse Width Modulation) control.
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. 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. 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. The best part is that this cable comes with 4 pin Molex connectors, which is rare among most options. The first 15.75 inches of this cable are bare. After that, there’s a series of four 4-pin connectors, each of them spaced 3.94 inches apart. We would have liked to see a little more length between the connectors. But other than that, we were very happy with the performance and design.
The Overclockers Difference
Ensure that the splitter is compatible with the size of your fans, as different fans have different connector types (e.g., 3-pin or 4-pin).
