I recommend adding some more cooling fans to this computer case ASAP.
I have not re-read this entire thread to see if it was already mentioned, but I also recommend your removing the heat sink off of the processor and cleaning off any dried thermal paste, if there is any, and remove any rubber looking mats off the the heat sink bottom if they exist, then add a bead of new paste to the processor core's head, this compound helps transfer heat from the processor core to the heat sink and into the air, where it belongs, so it can be exhausted out-side of the computer case.
Make sure if you remove the heat sink you re-install it exactly like it was before you removed it.
You need to bring that 138 degree fahrenheit temperature down to at least 100 degrees or below, aiming for 70 to 80 fahrenheit degree mark if you can.
