nothing permanent, im looking at liquidmetal pads to replace the compound, ive also heard that there is the possibility the shims that protect the cores from the block being tightened too far may be a shade thick so i may try sanding them down a bit to try and get better results, i wish they hadnt hardcoded all the cutoffs and detection things (eg one of the units i look after cant read the waterpump hence the board wont start with that pump connected) were it not for all that we could easily swap out the cooling system in place for a stronger cooling system, not that its not possible still, its just a bit more of a pain

one thing that does seem to help is regular restarts, you can add a cron job to resart the system every few hours which seems to help a bit but not too much
