EVGA Z590 DARK (122-RL-E599)
Fan Header
The Z590 DARK uses 4-pin fan headers, which are backwards compatible with
3-pin fan connectors. Fans may be controlled by PWM or DC controls. The
headers have an absolute safe power limit of 2 Amp @ 12 Volts (24 Watts).
These headers are for your CPU heatsink and chassis cooling fans.
The Pump header on the motherboard supports up to 3 Amp @ 12 Volts (36
Watts), and is primarily designed for watercooling pumps or AIO pumps.
All pump headers may be controlled in the motherboard BIOS, and each header
may be controlled as a Smart Fan or a manual speed.
