I think however they're just standard fans, so if you were to say, nip to a PC shop (online or not) and buy the correct size (and airflow obviously has to be same or better on the replacement as the amp will be designed for a certain minimum flow in mind for cooling), and look for "quiet" pc fans, you should be fine.[/quote]
I emailed straight away to Ashdown a few days ago, but I have yet to hear a response. I might try again.
