I mentioned to you before that you think your motherboard is reading from the diode but it isnt. There are surface mount thermistors inside the socket, and when you point a fan at the area you are cooling the PCB and the socket area, moving air around, and getting lower temps. I could make the "CPU" temp of my A7V-133 (also a surface mount resistor) fluctuate with a fan as well. The temp never changed with a homemade diode reader however.
