Fujitsu-Siemens offer two lines of motherboards, their 'premium'
series which are equipped with 'Silent Fan' technology and their
'value' series which are equipped with the stripped down 'Silent Fant
LT'. I would like to know what the exact difference is between these
two versions. Specifically:

- The promotional brochure for 'Silent Fan' describes how the user can
switch between 'silent' (CPU throttled before CPU fan is notched up),
'auto' (fans usually run at minimum, and the CPU is throttled
simultaneously as fan speed increases) and 'enhanced cooling' (fans
usually run at minimum but increase in speed as the CPU gets hotter.
No throttling takes place until the CPU is near its critical
temperature). Does the bios of 'Silent Fan LT' equipped boards also
allow switching between these three settings? In particular, I would
use the 'enhanced cooling' configuration so do the 'LT' boards support
that?

- As I understand it, no control software ('SystemGuard') can be used
with LT equipped boards so I would assume the various temperatures at
which the fans switch modes are set in stone, is this assumption
correct? If so, at what temperature does the fan begin to ramp up from
minimum speed (I assume this is different for both the CPU and the PSU
fan, so I would like figures for both) and by what temperature is the
fan running at its maximum? Also, what temperature is considered
'critical' by the motherboard?

- Related to the previous point, do the 'LT' boards support control of
the PSU fan and the case fan as well as the CPU fan?

- Is there any technique the end user can use to monitor the
temperature of the various temperature probes on the CPU/motherboard
etc. along with the current speed of the fans?

- Finally, if the responses to any of the above are negative, do you
know if Fujitsu-Siemens are planning to release a LGA775 micro-ATX
motherboard in the not too distant future which supports the full
'Silent Fan' spec? I do not require this information if you do not
know, but it would be helpful to me.

Thanks for your help,

Ken.
