My ACA620 wasn't provided with any means of fixing other than clipping it on the 68000 - It didn't mention anything else in the instructions that came with it either. Mine was one of the early ones though that also had a firmware fault (freezing/crashing). These earlier units had to be returned to Jens for a firmware update. So make sure it has the Revision 2 firmware loaded.
The 68020's in A1200's get pretty warm too btw, so nothing abnormal here.
Anyway, nice system! And welcome back to the forum.
