Good link, not heard of that stuff so added to my favourites in the
Material Supplies folder
Funny you should mention cooling the PCB as I'd considered this, I was going to resin coat the underside so it was flat and all conductive traces & pins were insulated then use a full size thin copper waterblock in contact with it. The resin wouldn't have been a good transfer medium but with my cooler coolant the block would lower the temp of the resin a PCB a fair amount helping to cool the components. Like so many things I never got around to it, and to be honest I don't think the Enermax needs it as it's fine heatwise with the way I have it now.
I may do it in the next PSU mod, (if I do another). Was thinking that I could raise the PCB so it was about half way up the case, then transfer the mosfets to the back of the PCB. This would keep their pin trace length the same and allow them to be mounted easily to one block under the PCB. The only issue with that is the transformer wont be cooled, but if it were done with a form of PCB cooling it may work ok?
