Leak Test; Cable Adapter

[rafe_28]

So i want to build a system and Leak Test it ofc. since the pump/reservoir combo i got (EKWB SPC 160) only has a 5 cm pwm cable for some reason (i will get an extension) i cant leak test it by shorting the 3rd adn 4th pin on the 24 pi because the PWM headers are obviously not gonna have power. But can i use one of those Adapters to have the Pump connected to my PSU for leak testing purposes?

If you leave the PWM cable disconnected, the pump will run at 100% (a feature of most, if not all D5 pumps). The PWM cable for the pump carries PWM Signal & Tach wires - no power; power is supplied via the Molex cable. You have no need for the adapter you linked.

It doesnt have a molex. Its jsut pwm

And its not a D5. Its some Ek specific pump.

@rafe_28 - Sorry, I incorrectly assumed D5. Yeah, the cable you linked in the first post will be fine. It has the same pinout as the EK-Cable Pump Testing Adapter (Gnd & 12V) and there is no need for the PWM signal as the pump will default to 100%.

Ok tyyyy. 

I am always a bit cautious with cables
