Hey Corey have you seen anyone running their fans through their Apex controllers yet......
Pretty sure there's at least 1 or 2 guys on the big thread who've done it. Another guy for sure doing it on his Dim4 controller.
It's all the same principles. You're just providing a 1-10v signal to drive the fans. Same as the led drivers dimming circuit. Most fans are 12v d.c. so you'd be sacrificing 2 volts if you went that route. You just can't do it with 10v modulated (pwm signal).
That's all those fan controllers are is another variable voltage resistor. It's all the same thing.

STOP POSTING!!!! 0 new posts this morning, i hop on at 7:00 and there is 70 new posts!!!!
I would have it so the fans are on their own circuit hooked up to a temperature probe and just have it almost idle, and kick up the hotter the heatsinks get so the heatsinks don't go above 80* or so. if you could figure out a way to do that.
And now im hungry again, DAM U ALL!

80 is setting the bar pretty high isn't it? How hot do the U channels get on your lights mid day?

Agree the 80 degree is setting the bar high.....What was your pull down again Corey......I was actually pleased with the pull down you got on yours....I'm just opting for the additional fan due to bigger heat sink area.....
Josh what is your reasoning behind putting them on their own separate controller.....Again that was my original plan/thought, but Corey pointed out the mere fact it could easily be accomplished run through the Apex controller.....I'm truly not interested or evening looking at any minor controllers for this function when it comes to my lighting.....It was a hard enough decision between the Profilux and the Apex controller.....
Actually a buddy stopped by the other weekend and he's trying to convince me to buy the additional display for the Apex and mount the 1 display in wall next to the tank.....He's definitely trying to make more work for me......

I haven't done any extensive thermal testing yet. But preliminary tests would apear that running my xpg's at 1000mA and my reds at 700mA with both of my fans running the heatsinks stays around 86 degrees. Without the fans they get upwards in the high 90's. But if you can keep it down to about 80 you'd be in real good shape. Anything less than burning hot will help the leds out but the cooler the better.

I didn't think you were running the XP-G's at 1000ma......
You're right. My mistake. I was running them at 100% and 70% on that controller but on my 5v channels. But actually I think I was running the drivers wide open when I took those first thermal measurements. So that would have been 1.26 amp on my xpg's and 830mA on my reds. So that's not bad at all. Ofcorse I plan to do more testing and I'll re verify. It's still a little cool out in the garage right now. It will be different come mid summer.

Those drivers are causing major fits.......I was just curious because I thought you could push the XP-G's to 1500ma....But I know you don't want to run the max out anyways......
Dude I don't know what's going on with Mean Well. I'm a little bit leery of them right now. I think there's more to all of the changes they've made than meets the eye. But yeah, XPG can go to 1500mA but the driver maxes out at 1.26 amp. I wanted it that way so I couldn't exceed max current of the leds.

I think in my original layout with how I had it laid out I was right around 833ma on the XP-G's.....Not wanting to drive them crazy....I have to dig out my notes......
I don't think I'll have much of a need to every push either of these colors past 700mA. I have so much light packed into such a small space I might be able to get away with half of that. But that's the beauty of a controller with being able to set intensity and fade time. You don't need mid day sun all day long.

Alrighty guys.....Again a big Thanks to Al......Just sent the drawings out to (2) of the shops I'm looking at to do the mill work on the heat sinks....Hopefully I'll have some quotes back by mid week. The 1 place I sent a the info to is actually 1 of my delivery customers on my daily route, so hopefully Plouse will take the job, but who knows!!!!!!!

Agreed Corey, Now Shawn. if you hook up the fans with the LEDs in the apex, what if those 12-18 fans get loud and aren't needed to be ran that high? what would you do in that circumstance? Oh, and I'm starting my 18g Cube thread, https://forums.saltwaterfish.com/t/390454/snapples-18g-cube#post_3458217
It won't be any sort of decent until it gets water but its started!
