Change CONTROLLERFAN_PIN for board 35 to -1, as it would conflict with board's 33 extruder pin, causing burnout (it's the same board, just different number of fans/extruders, therefore should be pin-compatible)

   #if MOTHERBOARD == 35
-    #define CONTROLLERFAN_PIN  10 //Pin used for the fan to cool controller
+    #define CONTROLLERFAN_PIN  -1 //Pin used for the fan to cool controller
   #endif
