Open source and hardware (GPLv3+) advanced programmable cooler controller.
- Automatically learns cooler characteristics: at power on it determines minimal voltage at one cooler starts, minimal RPMs and maximal RPMs, so you don't need to adjust temperature-to-RPMs settings for different coolers;
- Cooler speed is being controlled via RPMs loopback (using tachometer), so 50% RPMs will actually be 50% RPMs, not just a half of power voltage. In addition if something affects cooler RPMs, voltage will be adjusted to keep desired RPMs.
- Control tool to configure temperature-to-RPMs curve. Using this tool you can set up curve via changing values in table, view how curve looks and finally generate EEPROM HEX file to flash it into controller.
