I did a quick Google search about this setting and people say that "PWM" is better than "Auto", so i did what they said, i changed the setting from "Auto" to "PWM", my question here is, what does it actually do? I mean what are the advantages of using "PWM" than "Auto"? Is it better? Because i'm a bit confused here. I went to BIOS to check for any Fan settings for my CPU, i checked every section except the last one which was "PC Health Status", i went there and saw the setting "CPU Smart FAN Mode", this setting was set to "Auto" i clicked on it to see for any other options and i saw "Voltage" and "PWM".

Rule 2// The screw holes between the two fans must be 15mm width on the radiator for either 120mm or 140mm UNI FAN.Hello everyone, first of all, English is not my mother tongue so i hope you understand what i say.

Rule 1// The tubes of the radiator must avoid the tenon of the UNI FAN and be at the safe area, which is in grey in the image. Radiators that doesn’t follow bellow rule:.CORSAIR Hydro Series™ H110i GT 280mm Extreme Performance Liquid CPU Cooler.CORSAIR iCUE H115i RGB PRO XT Liquid CPU Cooler.Listed radiators are known not compatible with UNI FAN.To connect more devices, please update to L-Connect 2 (reference to update guide) and use 2 or more controllers. Do not connect more than 10 UNI FANs (device up to 21W) to the controller (UNI HUB) when performing white static color.(Update your motherboard BIOS if necessary) Please enter your motherboard BIOS and set the correspondent fan header at PWM mode.Please note that the single-pack version does not contain this controller.

To control all 16 UNI FANs (4 fans each cluster) in one go, a controller is needed, no matter control with L-Connect software or sync to the motherboard. Purchase a three-pack SL120 or a two-pack SL140(including a controller) as the starter kit for fully experienced UNI FANs with L-Connect.
