1. Compatible with a 12V 10A power supply; performs best with small tanks (25L or less).
 

2. At an ambient temperature of 32°C, with water at 30°C in a 25L tank: after two hours of operation, the temperature drops by 2°C; after four hours, by 4.5°C; and after six hours, by 6.8°C.
 

3. Extreme‑case test: at an ambient temperature of 30°C and with 20L of water at 45°C, running for one and a half hours results in a temperature drop of 14°C.
 

4. The entire unit is 3D‑printed, featuring a modular design that uses mortise‑and‑tenon joints combined with hexagonal screws for secure assembly, ensuring exceptional structural strength.
 

5. Future upgrades include a larger tower‑style cooling fan; design files and 3D models are available free of charge, with options for custom printing or DIY modifications later on.
 

6. Some hands‑on experience and basic knowledge of electrical circuits are required.

7. This product comes equipped with a built-in temperature sensor accurate to within 0.1°C, with a factory‑set operating range of 26–30°C.
