Panx Important: it must be connected to a sensitive RCD circuit breaker (i used 30mA RCD), it's the only safe way. The RCD can save lives, in a case of electricity leak, or a malfunction it automatically switches power off.

Panx This is instant water heater. You turn it on when you need hot water, it's tankless so it doesn't keep hot water inside.

panx Thereis a channel in Youtube: tvboxstop . There is a video with fan installation, the fan is connected to motherboard's corresponding connector, a complete disassembly of the box is necessary. They didn't show fan specs. They have email link under the video, you can ask for fan specs. i'm not sure but I think is a 3.5cm x 3.5cm uknown thickness, 5VDC, 2 or 3pin connector. Better ask tvboxstop. Anyway without a fan i have tested it for 7 hours of continuous operation without any overheating issues, so fan is just an option.

panx IDon't know for sure. I've tested it on my Toyota. Check if your car is OBD2 compliant as it is this scanner.
