So the power supply on my SQ80 has been overheating. After a while the whole keyboard will lock up with no response to either the keys or panel buttons/sliders. If I restart it, it will work for a short time before overheating again, and the overall time it takes to lock up depends on the ambient air temperature. During the summer it takes about twenty minutes, during the winter it rarely happens.
I already intend to replace the original EL caps on the PSU so that the voltage regulators don’t have to work as hard, but I was also considering replacing the regulators themselves as well as the thermal compound between them and the heat sink. Has anyone else tried this on the SQ80 or another board? Will something like arctic silver or mx-4 CPU thermal compound work? Any other suggestions for overheating issues?
I’ve considered attaching some small fans to the heat sink as well, but that’s a last-resort scenario.
