I had already written about MSI's fan control in their Z270 Build Guide, so I decided to use my images from that article since they have been modified to describe the different settings. Another neat feature MSI has are two RGB LEDs, one next to the CPU and Pump fan headers on the Z270 Gaming M7, and they will go red or green to signify they are in PWM or DC mode. While all their headers are DC/PWM hybrid, MSI does list exactly what the control signals will change to depending on mode changes. What MSI does very well that other vendors don't typically do, is list exactly what the default mode of all the headers are and which headers are auto detection. MSI outlines that they have many headers on their motherboards, and all of them are hybrid DC/PWM mode headers. It's very useful for PWM fans and gives you the lower duty cycle so you can correctly set your low points for less noise. ASUS Z270 UEFI OfferingДЄSUS offers Qfan Tuning which goes and calibrates all of your fans. The card provides many extra fans headers and temperature sensors, all of which can be programmed through the UEFI and software. ASUS also has a fan extension card, but not all ASUS motherboards support the card.

The Apex also offers two temperature sensor inputs you can use as a reference for the cooling curve.ДЄSUS is also nice enough to give everyone is a full overview of the current and capabilities of their fans, we can even see which headers have shared control.

The Apex goes above and beyond for overclocking, and that is why they have full speed headers, it's not a common sight. You can tell if an ASUS header is hybrid or PWM because on their full speed fans they list 12v as the voltage on the power pin, and on the hybrid, it's labeled as fan power. Most of the headers are hybrid PWM/DC fans, except for three headers are do full speed on both voltage and PWM mode fans. The ASUS Maximus IX Apex is a very loaded motherboard, and it has tons of fan headers built in. One of the benefits of PWM mode is that you can use one of these splitters and not strain the motherboard's fan header.ДЄSUS Z270 Fan Control ASUS Z270 Fan Header Offering You should stay away from putting too many PWM fans on one header as they constantly pull 12v, I would instead get one of the splitters that expands the 4th pin to many fans and gets 12v directly from the computer's power supply.

In PWM mode the fan is fed 12v constantly, and then a PWM signal is sent up the fourth pin to the fan to control it. PWM control is also used in your VRM and throughout your motherboard in many different places.

If you feed a fan 12v constant and use a 50% duty cycle PWM rate, then you would theoretically get 6V. That would result in a 50% duty cycle since you are pulsing (turning on) half the time. So let's say in a 10-second cycle we pulse five times to 100% for one second each time. These pulses result in a duty cycle, which can be used to calculate final voltage. PWM Mode (4-pin fans): Stands for pulse width modulation, and it basically means you get pulses (basically going to an ON position) at a periodic rate, and in this case, it's thousands of times a second.
