Choosing case fans
Check the fan size your case takes and the headers on your motherboard before choosing looks.
Size
140 mm fans move the same air as 120 mm fans at lower speed, so they are quieter - if the case supports them.
PWM or DC
4-pin PWM fans let the motherboard control speed precisely. 3-pin DC fans work too, with coarser control.
Lighting headers
ARGB uses a 3-pin 5 V header, RGB a 4-pin 12 V header. They are not interchangeable.
Common questions about case fans
Can I plug ARGB fans into an RGB header?
No. Connecting a 5 V ARGB device to a 12 V RGB header can damage it. Use a matching header or a controller.
How many case fans do I need?
Two front intake fans and one rear exhaust suit most builds. Add more for powerful GPUs or hot rooms.
