Since I found that the temperature values of the SMIOVT listings did seem to vary some according to the operation of the PC, I kept Googling and finally found that they are RAM temps. Why there are 3 of them, when I only have 2 sticks installed is beyond me, but I have them disabled on the display anyway, because when they are displayed, there isn't enough room for my hard drives, which I'm more concerned about. However, I have noticed that the RAM temps vary between 37-45 degrees, I'm now wondering what I should consider a max temp for them?
