In 2024, I redesigned the InaMORAta to use 5v ARGB fans (the previous design used 12v RGB fans). I also significantly simplified the electronics.
Components
- Mo-Ra3 420mm radiator plus front cover
- 9x 140mm Arctic P14 ARGB 140mm fans
- 12V AC adapter rated for at least 9A (108W)
- 12V->5V buck converter rated for at least 5A (25W) output
- CODI6 (controls ARGB, distributes 12V+5V power to fans)
- 2x SATA splitters
- One SATA power cable (4 wires)
- 4x heatshrink solder tubes
- EKWB EK-XTOP dual D5 pump
- Perfboard, onto which is soldered:
- Espressif ESP-WROOM-32S microcontroller (controls fans, sensors, provides MMQT+WiFi)
- 4.7kΩ resistor
- 3x 0.1nF ceramic capacitors
- 3x 10kΩ resistors
- 3x 3.3kΩ resistors
- 3x Molex 4-pin fan headers
- DS18B20 digital thermistor
You'll need a hot air gun and a soldering iron (plus whatever you use to assemble the Mo-Ra, and attach things to it).
Power
We have power requirements at both 12V and 5V, ultimately sourced at 12V. The 12 LEDs of each PF-14 take 0.4A at 5V. With 9 of them, that's 18W. The ESP32 will also draw 5V, but not more than a watt. Assume 90% efficiency for a total of 20.4 input watts. At 12V, we have 23W to each of our pumps (46W total). Each fan takes 0.17A of 12V, and thus 9 draw 18.36W. That's 64.36W and 20.4W, a total of 84.76W. 85W at 12V requires just over 7A.
- 12V AC adapter runs to barreljack on/off switch
- On/off switch takes 12V to SATA and buck converter
- The two sets of three wires are connected with two heatshrink solder tubes
- Buck converter takes 5V to SATA
- The two sets of two wires are connected with two heatshrink solder tubes
- SATA takes 12V+5V to SATA splitter
- SATA splitter takes 12V+5V to CODI6 + SATA splitter
- SATA splitter takes 12V to 2x pumps
We don't need to expose the 5V to the pumps, but it doesn't hurt anything.
