Thanks a lot for your advice eKretz,
when I changed the motors the first time I recognized that the drivers below the heatsink were not even and
the gap has been filled by thermal compound which isolates more than taking the heat away.
I expected more precision on a product engineered by a german company......all that glitters is not gold......but the german motors put the record straight!
As I did not want to solder on the PCB to put the drivers on one level I decided to match the heatsink´s "landscape" to the level of the drivers by sanding/grinding. Now it is just a touch of thermal compound (bought the right stuff at my computer store) between heatsink and driver to enhance cooling performance. The guy from the computer store
recommended thermal compound patches but I like it old school and I´m sure it performs better.
Here´s a drawing:
I also mounted a heatsink on the back, isolated with glimmer/muskovy glass from the PCB to avoid short circuit.
You can see a very slight "bow" in the main heatsink - that´s the grinding I did - not much but now it´s very tight:
Got the confirmation that my fans are on the way - I hope to post some photos soon.
Happy 1st Advent - it´s below zero here and I´m gonna test out some hot wine punch on
the xmas market. Cheers!
