Due to work and a project my wife asked me to do I've not been able to do anything on this project. I've ordered different transistors for the fan circuit and it's on it's way from China...
Pinhead: I tried returning your PM but your box is full.

Well, got all my proper parts from China for the Fan pwm control to build it exactly as per drawing above, and the PWM speed control still doesn't work... argh.

Gonna resurrect this. It's going to be the only thing holding me back from my tank upgrade soon. I built another circuit board to exactly match the one in post #214 last night. Plugged 'er all in this morning with one heatsink and it's doing to the same thing. Heatsink temp is at 38.6C and the fan hasn't ramped up. It's still running at the same speed it had started at. Maybe something in the sketch...

Lol, ok, I'm an idiot. I was wracking my brain thinking of anything that could be the problem. The fan still hasn't been ramping up and down via the PWM signal according to the temp sensor on the heatsink. I have a DS18B20 sensor that looks like a BC549 transistor, sunk into my heatsink with thermal compound and that's controlling my fans. I also have another one that is attached to a cable and sealed in an encased water proof housing like in your manual.
So I wondered if it was working properly. As soon as I grabbed it and watched the temp on the monitor go up, I realized the fan was speeding up  Duh, I must have either screwed up the pin assignments or something. It's been a long while since I set this all up, so I have to go back and read in the manual what's making all this work. But at least I've got an idea what's wrong now! LOL I haven't fixed it yet, but I'm still relieved.

Dude... no idea what you just said, might as well be speaking Swahilli... does it go beep beep like R2-D2? Lol.
Honestly though, I'm glad you figured it out. Are you going to be using this on your new build?

Haha, that's how I felt when I first embarked on this little adventure.
Ya, that's the plan. 3 - 18" full spectrum fixtures,

WOOHOO!!! Got it fixed. Now everything that I have hooked up is working as it should... only thing is that's 1 out of 3, lol
Hopefully it's just a matter of repeating what got done right on the first
