If the thermal pad isn't making good contact, your internals will be much hotter than the external case. Taking it apart is not difficult; just use a small flat-bladed screwdriver and GENTLY pry the metal slab from the case. Then, you can gently pull the slab off the FETs.
I still don't know what happens when the Quark goes into:
-'safe mode'
-LVC
-and a thermal shutdown
I we knew this, then we could better trouble-shoot the Quark.
