INSTRUCTIONS Remove the stock cooling fan. A ball-point pen with the ink removed is a handy way to compress the plastic lock pins without damaging the ODROID. Be careful to minimize stress and bending of the ODROID's PCB while removing the old heatsink and installing the new cooler. Clear the surface of the CPU and cooling fan of any old thermal compound. Apply the thermal paste to the CPU. Make sure to cover the entire surface of the CPU that will be touching the cooler. Install the new cooling fan by lining it up with the mounting holes and pressing the mounting pins through the holes.
