This is an upgrade body for the ISDT C4 battery charger that eliminates its biggest issue - extremely loud fan. The custom body is designed to hold Noctua NF-A4 fan (10mm version) which is extremely quiet and barely noticeable.Please refer to the video for detailed overview and assembly instructions.Version 2 has a different design of air intake cut-out for easier printing.Print in PLA (due to steep angles) with max 0.2mm layer height. I would strongly recommend using support and/or slowing down the print by at least 30%.

Parts required:

• ISDT C4 charger
• Noctua NF-A4 10x40mm 5v
• Optional: JST-XH 2pin connector (2mm JST)
