![]() ![]() ![]() PWM can cycle power on and off extremely rapidly. To maintain positive pressure, you need to have a higher combined CFM for the intake fans than the exhaust fans. A four-pin motherboard fan connector enables a feature called Pulse Width Modulation (PWM). When adding fans to a system, maintaining positive pressure within the case can prevent dust from being sucked into any open holes or crevices. Some manufacturers incorporate LED lighting into their fans as well. Larger fans can usually spin at lower speeds and still move plenty of air without making much noise. Some fans even come with built-in LED lights, others are more performance focused such as this Noctua Chromax fan. Thiago Trevisan/IDGįans vary in size, speed, blade shape and color. This information will be on the package or on the product’s information page. Look for one with a high air flow (measured in cubic feet per minute, or CFM) and low noise level (measured in decibels, or dBA). Fans with a diameter of 120mm are typical in newer cases. 108,160 221 50 Featured Download By Core3D core3d.tech Follow More by the author: About: Avid 3D printer builder, currently completing my 3rd printer design. It is strange it shows one speed but a voltage range.The most common fan sizes fall in the 70mm to 140mm range, but fans as large as 230mm are becoming more popular. All are (6)4 pin headers for the fans except one and it is a 3 pin header. When you buy the fan make sure you can control the speed: If you don't own a fan you can find some fairly cheaply but you need to find out what controller you have. Set to 100%, then 40% to see if the speed changes.ĥ) Example fan profile: case fan at 40% speed until 40degC then RAMP up to 100% speed at 80degC (it will never reach 100%). May have to just try a fan).Ģ) Enable fan control in the BIOS if needed.ģ) Download and install your motherboard fan control software (motherboard support site).Ĥ) Play with the fan profile. ![]() Older motherboards may have VOLTAGE only for everything.ġ) Determine what TYPE of controller you have (not always obvious. ![]() My motherboard supports both PWM and Voltage for the case fans, but only PWM for the CPU_FAN controller. The two types are:Īdditionally the FAN controller must be capable of controlling this. MOLEX is usually not controllable, though there are some rare exceptions which work with 3-pin/4-pin adapters. *There are two types of fans that have speed control. ![]()
