Fans will not start, need a usb 3.0 adapter

[DesertDweller_1912]

I recently bought a 7000D Airflow unit. I put in an  ASUS Prime Z390-A motherboard. The motherboard has one 3.0 20-1 pin socket and the case has two 3.0 20-1 pin cables. With one cable connected 2 of the four usb sockets work on the front panel. I looked for an adapter to plug in the second cable but couldn't find one. Is their an adapter for the second cable?

Second question, I cannot get the fans to work. I plugged in the fan cable to the ext fan on the motherboard and nothing happened.. Is there a switch i need to flip? I looked on the circuit board, couldn't find anything to start the 3 fans that came with the unit, all three fans are plugged in.

the EXT_FAN is for an optional fan extension card. it's not a fan header. it's a 5 pin connector too, fans are 3 or 4 pins 🙂

To avoid cable clutter, you can connect the case fans cable to CHA_FAN2 (chassis fan 2) on the edge of the motherboard.

You can then set a fan curve in BIOS, or install Asus AI suite in windows to do the same thing, and set the kind of speed you want.

 

for the front panel USB3 you have two choices mostly :

An adapter cable to connect to a USB2 header, but you'll have slower USB2 speeds : https://www.amazon.com/LINKUP-Motherboard-Compatible-Converter-Chipset/dp/B084D58HBP

A PCIE USB3 card with an internal USB header, and here you'll have the full USB3 speed. That one is just an example, there are tons of models with more external ports etc  : https://www.amazon.com/FebSmart-Ports-PCIE-Self-Powered-Technology-No-FS-HA-Pro/dp/B089ZXXVHY
