I *really* don't mean this negatively, I mean these sites/articles are very much appreciated, but the article on making an A2000 fan silent made me LOL.... calm his blower

EDIT: just realise this is in fact google... which makes it even more LOL
The first solution was provided to us by René Beuchot Lagnieu who want to remind us that the warranty is void as soon as Commodore tamper in the bowels of our Amiga, even if it is in the laudable intention to calm his blower.
His solution is like this: you must first start by finding four tiny son pass (within 3 mm) in a good online store, for example, and four nuts and bolts of 3 mm. Then the body of the A2000 is opened (five screws) and food (a little screw) It blew the rivets that hold the fan and pass son is put into the holes of the body after be increased if necessary.
It only remains up doing well blunder not to trainner chip in the Amiga (she hates). Can be further improved by replacing the fan with a model 220 Volts, quieter than a 15 Volts DC origin: there is, on the power supply board, two free pin where the son of the area that can come plug.
That is to mount the fan on "silent blocks". René uses these two changes for a year and his life with his Amiga back in much better terms.
