<div class="moz-cite-prefix">Hi Mark,<br>
<br>
Because each channel is unique, I suggest looking at the behavior
of the pedestals on a per channel basis for each crate and as
follows:<br>
<br>
a) Fans with fixed 4,000 RPM<br>
b) Fans with fixed 4,000 RPM and active pedestal correction. There
are various ways of determining the time interval for corrections
but one could be based on a), above.<br>
c) Fans with variable RPM from temperature feedback.<br>
<br>
These tests can be performed after the current run is concluded
and each of these tests could be performed over one week, say. My
expectation is that the behavior of a pedestal will be very
distinct on a per channel basis, even though it is not obvious
from the mean. <br>
<br>
Thanks and best regards,<br>
Fernando<br>

Folks may be interested in seeing our pedestals over time for the
spring run.
