I just used a Dremel on my lower case to carve out a nice cavity of clearance for the fan plug. Much better!
I did notice something else that concerns me.
There are TWO resistors directly above the circuit board support rail. One had been clearanced and allowed for. The other had NOT.
The one that needs attention is on the power output side right on the edge of the board. The fix for this is just to remove a small amount of material from the rail so the weight of the board isn't pounding on the resistor.
I'm not sure what would happen if this resistor broke off. My guess would be that it serves as part of the filtering for the emf return to the brain.
