Molex 4 pin connector install#

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. The directions also say to use seperate chains to power a 8pin, as using 2 molex on the same chain at upto 180w is a fire hazard. It's the reason molex to pcie 8pin adapters use 2x molex but a single for the 6pin. 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%). Molex chains use a single 12v or 5v lead, unlike pcie which uses 2-3 12v leads per connector.

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. Micro-Fit 3.0 Blind-Mate Interface (BMI) Connectors are designed for blind-mating applications. OEMs often need power connectors in space-constrained applications. The two types are:Īdditionally the FAN controller must be capable of controlling this. The Micro-Fit Connector Family offers up to 8.5A with a 3.00mm pitch, delivering power in a compact package in wire-to-wire and wire-to-board configurations. 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. Micro USB connectors offer a compact connector design, reliability and an overmolded receptacle for optimal space savings.EXAMPLE PWM FAN (it's 92mm. These are all available with 4-, 5-, 6-, 9-, 14-, 16- and 24- circuit sizes.Īs devices in various markets become increasingly small, manufacturers require reliable compact connectors for their designs. With PWM you need a circuit that can send these pulses. Its analogous to spinning kids on a merry-go-round.

2) 4-pin fans are PWM (Pulse Width Modulation) which means they get pulses of energy applied to spin the fan. Molex hybrid USB receptacles and plugs offer a wide range of options that include USB 4, Gen 3 and Gen 4, USB 3.0, USB 3.2 Gen 1 and Gen 2, USB 3.1, USB 2.0, USB-C, Micro USB, and Mini USB. Hi, 1) I suggest you get a proper 3-pin, non-variable fan rated at roughly 1000RPM. Industries are challenged to meet more complex design requirements and therefore need design flexibility for their applications. With an IP*8 rating/waterproof option and up to 40 Gbps (USB4 Gen 4 speed), Molex offers a wide range of USB type connectors. USB 2.0 and Micro-B offer an IP67-rated waterproof option that withstands post-solder reflow while minimizing water ingression. Many consumer and industrial applications experience wet conditions that could cause failure in connectors. With 3.0A/5.0A current to enable faster and safer charging, Molex offers a wide range of USB Type-C Connectors that are physically robust and electrically reliable. The mating tongue design protects the interconnects from possible damage caused by mishandling, shipment or assembly processes.

Molex’s USB Type-C I/O connectors use high-temperature plastic as housing material and a 3-tier insert-molding process to help ensure high mating durability. Most of our USB products are TID certified and comply with various dimensions to help prevent costly electrical damage. Some USB connectors don’t comply with the required USB specifications, which can cause costly electrical damage.
