12v molex pins

[Wing-Man]

I have a fan speed reducer this I would like to change to 12v can anyone help with the pin out

I’ve seen 2 photos showing the red wire in pin 3 and 4 so I wanted to be 100% and not blow up my new £70’s worth of fans

You spent £70 on fans and they still came with a molex connector? Thought everything nowadays was now 3/4 pin fan connectors directly connected to the motherboard. Don't think I've got a single molex connector on my new build.

No, I have a molex to 4 fan out. I want the fans at 100% but my mobo only as 3 fan headers and I have 6 fans and a pump

Why not just get a 2 or 3 way splitter for each fan header? At least you can still independently control e.g. intake and exhaust then if needed

Other option would be a proper powered Fan splitter cable (the Akasa below) that still allows you to connect the PWM Signal and control the whole lot via PWM, and also has a SATA power connector rather than Molex (so you don't need to keep Molex connectors e.g. on a modular power supply)

My basket at OcUK:

• 1 x EK Water Blocks EK-Cable Y-Splitter 2-Fan PWM (10cm) (SKU: WC-551-EK) = £2.99
• 1 x EK Water Blocks EK-Cable Y-Splitter 3-Fan PWM (10cm) (SKU: WC-9AK-EK) = £3.49
• 1 x Akasa FLEXA FP5S 5 Fan PWM Controller (AK-CBFA07-45) (SKU: CB-079-AK) = £4.99

Total: £15.47 (includes delivery: £4.00)​

I ordered one 11 days ago. I’m hoping soon they will dispatch it. But for now I’d like the fans working.

The fans are 2 shadow wings and 2 NF S12a so at full speed there all silent

I got the powered splitter so the 4 case fans can all run on one header. The pump can have its own header and the external rad can have 2 just on a splitter.
