Hi All,

I have finished my amp (LM3886 Bass amp) quite some time ago and much of my success is due to what i have read in this forum.

I recently bought some cpu heatsink/fan combos, there were about 100 of them in a cardboard box outside some shop selling for 1 dollar each (like little puppies you cant resist), so i got 3 of them...

I was thinking of using one of these as a heat sink for my amp since its in a quite small enclosure (an emptied out computer power unit). also because i am quite paranoid about the heat etc... its purely psychological, i know!

I was wondering first of all if someone has any experience with this kind of thing.
My transformer has un-utilised secondaries i think 7.5v - 0 - 7.5v which i would like to use for this matter.
I am guessing the fans are 12v, although there is no indication.

I am not too sure what implications something like that would have, and how should i power it from the secondaries, i probably need to give it dc so some kind of diodes or recitifier..
can the secondary amperage be a problem?

I am not the most experienced diy technician but i made it so far.

Much thanks, Gideon  :tu:
