<DIV><FONT color=#000000 size=2>Hi..</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2> Question: how badly do the
switch mode PSUs you get in external drive cases need their small , noisy, and
intrusive fans? I'm thinking of using one as a PSU for some ccts (Yes, I know
they give out interference like a small star).</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>I was thinking of:</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>a) dispense with the fan altogether; I won't be
pushing the PSU hard at all.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>b) swap the fan for a thermally controlled
'low-noise' replacement. The best noise figure I've seen for these is 24dBA,
from Farnell in the UK.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>Any advice appreciated</FONT></DIV>
