I'm building a lighting set up driven by audio data in max, and i was planning on powering it all from an old PC PSU.
I am driving 4 of these:
with 12 of these:
from the 12v line on the PSU, utilizing the dim pin of the pt4115 on those each of the driver boards with a PWM pin on my mega.
I am planning on cooling each of the LEDs with a CPU heatsink/fan (and thermal paste of course), will that be enough cooling? will the drivers need to be cooled as well? I plan on running this for at most 4 hours a session, not running them at full blast all the time.
Also, will the voltage drop be too much between all of the LEDs for the PSU to handle?
Thanks in advance -z
