There is no way to read anything on those VRM-boards: completely covered with the aluminum plate.

For quite sometime I ran the system in factory-default: but 3 of the boxes have high temps on the first VRM (about 106 C). This is partly because of the position of the boxes in my server-room (re-arranging them gives high temps on other devices), and partly because the aluminum plate isn't pressing equally on all the VRM's (especially the first VRM on all boxes has problems) >> So I screw the plate tighter on that side (which worked quite well).

 Still... I have tuned down a few VRM's to 450 Mhs instead of 475, for the time being (I will buy some additional Fans to solve this).
