DXF files to make your own 1-slot cooler and backplate for the A2000
works well for 1U rack mount servers with passive airflow:
- coldplate can be laser cut or CNC machined from >= 3.0 copper (3.2mm recommended), mounting holes designed for M2.5
- 1-slot bracket / backplate can be laser cut and bend from 1.0 mm copper / aluminum, mounting holes designed for M2 screws and nuts
- cut the coldplate and solder some copper fins on it using 138C solder paste
- cover the backplate with a large 1.0 ~ 1.5mm thermal pad (mainly for electrical insulation)
- fix the backplate to your A2K using M2x6mm screws, use M2 nuts or washers to offset the backplate by about 1.6 ~1.7mm from the PCB
- attach the coldplate to your A2K using M2.5x8mm screws
