Just connecting the Pi to an HDMI device will not provide any sort of touchscreen facility - HDMI is output only, and the touchscreen data need to get back to the Pi somehow. When connecting a HDMI monitor with touchscreen, usually there is a USB or similar connection as well.

You mus also install drivers.
Does your screen have Android drivers available?
Stop plugging your fan directly into the GPIO 5v
