Now, we take the unit apart and find a rifle bearing fan. With a 10 year warranty, I won’t worry about it lasting.

A nice and clean CWT based platform awaits us on the inside.

Soldering quality is CWT’s best work today.

Lots of cool parts are found here, including a PIC16F1503 microcontroller and a WT7502 protection IC. This is also where fan control happens.

Amid a forest of Nichicon polymer capacitors, we find the modular cable connectors.

Time to get some scoring done!
