How to Install the BLUE heatsink on ODROID-XU4.

If you use this BLUE heatsink, you will meet more frequent thermal throttling than the stock active fan cooler. If you want to keep running heavy computing loads constantly, lower the CPU Max clock to 1.4GHz to avoid the thermal throttling.

Prepare below items

- A 40x40x25mm Blue Heatsink and thermal paste Where to buy
- Alcohol
- Lint-free towels or wipes
- long-nose-pliers or tweezers

Step1: Remove the stock fan cooler

Use a long-nose pliers or tweezers. The other way to remove the heatsink is to use a retractable ballpoint pen. Remove the ink portion of the pen and then use the hole on the writing end of the pen to push the retaining clips through the holes on the XU4. Once they snap through, carefully rotate them from the other side while pulling on them, and they should come free.
Next, disconnect the power from the fan. Lastly, slowly pull the heatsink and fan away from the XU4. It will take some force as the thermal interface is adhesive. We normally rock the heatsink back and forth while pulling on it.

Step2: Clean the CPU and Heatsink surfaces

Clean the thermal paste on the CPU / PCB (if exists) and the heatsink surface carefully.
Apply the alcohol on a lint-free towels and use it to clean the PCB and the blue heatsink.

Step3: Apply thermal paste on the CPU surface

Place a small amount of thermal paste to the CPU surface and spread the paste evenly across the surface.

Make sure to cover the entire surface that will mate to the CPU.

Step4: Install the CPU Heatsink
