Yeah, at least the CPU fans I've seen never go completely off. I feel like its an extra safety feature so you dont fry your CPU. It's pretty nice here too, I know I can never totally turn off the fans. Plus the control lead on the 4-pin fans, if it ever goes floating (like most GPIO pins on the rpi seem to do after reboot), the fans go to 100%. So on power-un, during Linux boot and stuff (for me), it defaults to 100%. sounds like a desktop starting up lolOn a somewhat related topic, I was just looking at the tech sheet for the Arctic F8/F12 and it shows fan speed of about 450rpm at 0% pwm with 12v power. With 5v or 7v power, the graph shows 0rpm up to 10%pwm, then the fan kicks on. Does this mean the fan is never actually off with 12v power?
The RPi was a good choice for me because I knew I wanted to run linux. But if you're not picky about that stuff, the arduino is definitely the way to go. They're both very capable machines for sure. But it's definitely a small linux computer- it's kind of a big jump in complexityThat's a nice safety feature for sure. I was planning on running the StormX as a result of not knowing much about Arduino/Rpi, but the more I think about it, the more I want to go that route. Got any good resources I should check out?
There are options to usi9ng a stormx controller for aquariums. You can build your own six channel controller or buy a six or eight channel controller from GrowGreen for less than stormx and works better too. stormx has one on/off schedule for all channels GrowGreen has six or eight on/off schedules with pwm dimming as well similar to stormx but better. GrowGreen uses both pwm dimming and on/off for each signal. just googler GrowGreen Led controller or PM me. I have been working on both arduino and RPI solutions.That's a nice safety feature for sure.
