do we have any electrical engineers in the house? i am wanting to "handle" my ATI fixture fans. SO here's the deal. .. ATI fixture has 2 fans (red / black wire just power and ground) they have no control just on / off. i am thinking i would like to replace the fans with same size 60mmx10mm but with 4 wires. (ground, 12V, speed sensor and PWM).

currently looks like this

any idea how i can set this up so i can control fan functions from my profilux controller using this breakout box (RJ12 Connection)?

Fan control doesn't have to be separate. they can both run at the same time and speed. any hints? i am thinking i wire the the power and ground at teh fixture and then run the PWM and Speed sensor wire to the ATI Break out box since that has a separate power supply connection for the fans

why do you want to control them? what is your end goal?
If you are trying to speed them up, there is a way to access the control board to up the voltage. ATI has an instructional video on you tube.

this is not a dimmable fixture (at least not the T5 Part) and therefore, no direct control over the fans. They kick in @ 100% when the T5's come on. my goals are the following,

run independent of T5 status
run at lower speed to reduce noise
enable control via Profilux

Hmm. My fans were running too slow and my fixture overheating, which is common with the ATI T5's. If yours run at 100% all of the time (yes mine are the dimmable), I would wager that your fixture needs everything those fans are pulling to not overheat.

i have an adjustable ac adaptor. i was running at 6v and reduced to 4.5v. its livable. the jet engine on my desk preventing me having a conversation was unacceptable.

edit: so the urgency is a little less lmao.. it may not be worth going through all the trouble.

also, 6 bulb fixture with 4 bulbs active running 4 hours a day.
