=======================

If you didn't exceed 55C, You may not have gotten to high speed 
with that test. Here are the results of my fan speed vs. temp 
test a while ago:

Time   Temp  Fan
0:00    26C   0
0:26    37    1
0:44    41    2
1:19    50    3
1:45    55    4
2:40    60    4
2:50    62    4
3:15    64    4
4:00    64    4

Room temp was 77F.
