Fanless \ Noiseless computer #1

    Here is the base. You can see the mobo standoffs (pos. №1). Ordinary standoffs, 8mm high. White traces of thermal grease mark aluminum spacer plates that remove heat from the VRM (pos. №2). A note to followers: before using this solution look carefully at the underside of the mobo and make sure there are no contacts sticking out of it - you don't want them shorted, do you? Their size and location are determined according to the location of the parts on the motherboard. They are screwed to the base with the M3 screws with countersunk heads. Four M3 threaded studs (pos. №4) screwed into the base allow to clasp the heat block to the processor. Another spacer plate (pos. №3) not only transfers the heat from the processor but also prevents the board’s deformation. All the parts are made of the 8 mm aluminum sheet.

   The underside of the mobo. These are pieces of silicon heat-conducting tape (0.5mm thick, reinforced with synthetic fibre) additionally smeared with thermal grease. Electrical insulation, just in case. 

This cutout in a VRM spacer plate was made because there were some small elements sitting on the motherboard's underside right at that spot.
