5/31/2023 0 Comments 3 pin fan pinoutHas anyone else gone through this dilemma ? Any help would be much appreciated (fan header pinout, Service Manul or schematics for Delta DPS-1050DB A, etc.). It is utterly confusing, to say the least – is the fan header pinout reversed in Z800 power supply, or the color scheme order of the fan wiring ? ** Based on perceived pinout – the right-most pin of the fan header on PSU PCB is marked with silkscreen printed ✱«. Wiring (color) scheme of ADDA AD0812VB-A7BGP fans appears to be reversed, compared to standard 4-wire PWM wiring/pinout.ġ. from cold start up.įan connector is standard 4-pin, differs a bit from HP proprietary 4-pin connector, so it doesn't fit the fan header in PSU out-of-the-box. This can be fixed by removing an inner plastic key/ridge on the AC F8 fan connector. Replacing factory default ADDA PWM fans (AD0812VB-A7BGP) in HP Z800 Power Supply (Delta DPS-1050DB A), due to high-pitch whirring sound they start to generate, after about 5min.
