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. 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.
Certain fan splitters also offer the ability to monitor fan RPM (revolutions per minute) or display the fan speed on an LCD screen.Opt for a fan splitter with cables long enough to easily reach your fans without causing strain or cable clutter. Additionally, select a fan splitter that supports low-noise fan connectors for quieter overall operation. 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. If you want to have control over the speed of your fans, consider a fan splitter with built-in speed control. The installation process was easy. I tell you, with this fan splitter cable, you’ll be having the cleanest possible outlook inside your rig. It lets you connect the fans with ease at random places around the motherboard.
Flexible cables make it easier to route them neatly through your PC case for improved cable management.PWM allows for more precise control of fan speed, resulting in quieter operation when the system is not under heavy load. If minimizing noise is a priority, look for a fan splitter that supports PWM (Pulse Width Modulation) control. Besides, all of the fan connectors are 3 pins, making it an excellent option for a gaming build requiring multiple 3pin fans. 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. 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:
You’ll have to go into your BIOS or use a third-party app to manually set the desired system temperature. A 3-pin fan will always run at top speed when connected to a PWM controller. While it will technically work, you’ll need to upgrade your fans if you want the benefits of PWM. 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 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. If aesthetics matter to you, consider selecting a fan splitter that matches the color scheme of your PC build.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. In my testing, I found that the fans connected to the splitters function seamlessly. There were no issues with the RPM as all of the fans ran at the same speed. No variations were there. 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. 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.
The best part is that this cable comes with 4 pin Molex connectors, which is rare among most options. Moreover, if you avoid fiddling, then this cable can be long-lasting, which ultimately makes it a great option. What is a PC Fan Splitter?Look for a fan splitter made of high-quality materials that can withstand continuous use and provide durability. Consider the power requirements of your fans and the power delivery capabilities of the fan splitter.
