When I replaced the trim pot with wires to an external pot, I had to remove the circuit board from the casing.
The thermal grease they used appeared to be just white zinc oxide.
I have a large tube of arctic silver and put a good amount on the thermal pads when I put it back together.
I do not think any more ventilation or heatsinking improvements are required. I could choose stronger fans than the Noctua's but I chose them for their quietness and durability. This unit will often float and actually be a power supply all night long in my usage, so quiet fans are a prime consideration.
Heck this time of year I use less electricity and have more solar harvest and have not really been needing any meanwell assistance.
But with this heat, bring on the marine layer, I'll gladly accept 2.3 amps at noon for 25 less degreesF
