I do the same.

Set the power out at 30W then switch the meter to ALC and adjust the
audio level for NO ALC indication. Switch back to RF on the meter and it
just flickers the third LED while transmitting. Nothing but great
reports. I've got two 80mm computer case fans arranged diagonally on the
heat sink drawing air through the fins up and out. A small square of
double stick foam tape in each corner of both fans holds them tight.

I do use the rigblaster+ interface. I have been thinking of swapping out
my tired old SB Live sound card for an M-Audio Delta 44.
