We are trying to keep our board in safe temperature ranges. It doesn't have a PC-like chipset with temperature sensors, so monitoring tools like lmsensors don't seem to work.
We made an experiment to attach a heatsink in a non permanent way (avoiding the thermal epoxy alternative).
Here are some pics of our setup:
|We divided a low airspeed heatsink in 4 small pieces|
|Some good quality thermal compound|
|And a few extra pieces to keep it in place|
The sink still gets very hot, so we are considering putting a whole heatsink instead of 1/4 of it.
