<DIV><FONT face=Arial size=2><SPAN class=943301810-28012005>hi to
all!</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=943301810-28012005>I urgently need to
know what internal gain assign for PC. We know new computers are much more
powerful (as processor) and new LCD monitors "sucks" few
electricity.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=943301810-28012005>En example (from
tech data on their back):</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=943301810-28012005>traditional monitor:
220V x 2.5A = 625We</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=943301810-28012005>LCD monitor: 220V x
1.5A = 330We (but a shop catalogue gives 40-50W power consumption for a similar
LCD!..).</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=943301810-28012005></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=943301810-28012005>(an LCD is
approximately 50% saving...right? but if I touch a traditional monitor I feel it
is actually pretty warm while the LCD one is at ambient temperature! It would
seem less than -50% consuming (as thermal gain I mean...). And in any case the
electricity charge it is not totally dissipated in heat...)</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=943301810-28012005>...so can anybody
tell me an average reasonable thermal dissipation? for LCD monitor and
PC?</SPAN></FONT></DIV>
