I toasted a Kontronics FUN1800. The thing got hot faster than the feigaos. It got over 300 degrees F on its last run. Oops....
Amazingly it still runs, but the burning smell never went away.
Took it apart and it still looked OK, just smells funny. Its been sitting in the motor box for quite a while now. If anyone needs a pretty paperweight or good hard drive eraser I'll let it go cheap.
