Running Darkside dimmable LED strip from QUADRO PWM fan header

Wednesday, December 30th 2020, 11:19pm

Hi folks
I recently changed my case lighting to dimmable strips from Darkside (12V, white) and I've been running them from one of the PWM fan headers on my QUADRO via a 3 pin cable (though of course with only 12V and ground populated.) Whilst they work just fine, the power slider seems to act as a binary, providing 12V/0.5A at any power setting but 0, which turns the strip off. I was just wondering if there was any way to dim the lights with the power slider or if I'm stuck at max brightness?
Thanks
Charlie

hi there

PWM is 12v with Pulse width Modulation the signal is on the cable the LEDs you power with 12V to dim there signal isnt PWM so assume the need 5-12V Voltage to dim

you need a Power Adjust module to achieve this from Aqua computer Products in the same way i have fixed 12V fans that now slow and speed up using the power adjust Modules and temperature. so your LEDS should follow the same process.

hope that helps.

Thank you for such a helpful explanation. I shall order one.
