11 o'clock is way too hot. That's like if you wanted to run 350MHz or higher. 3 o'clock and 100MHz should be at or under 1 amp draw.
I haven't touched it. Ever. So, 3 o'clock for 100 MHz, and see what happens?
And more importantly... 3 o'clock, with the USB side being 6 o'clock? As in pointing to the right of the stick, when I have it in front of me with the USB pointing toward me and the cooling block pointing away and on the other side?
