    My projector doesnt bother us being in such a large room but I was chatting to someone on a newsgroup and they said..

    'It's a common fan size in all computer power bloc. But in computers they
    are more silent than these ones. You can find power blocs in any small
    computer
    shops. There are lots of chineese computer shops in Paris which sell
    non-expansive computer parts.
    But the best idea is to get a dead one (in my company they have one per 2
    week...).
    With a bit of luck it would be silent. Just try it on a 12V or 5V DC
    generator.

    Also there are (not so) "special" silent fans in these shops.

    I don't know the model, and I haven't changed them already - only planned to
    ;)
    As my projector needs service, I don't want them to say "you have opened
    it and invalidate your guarantee" - even if it's easy.'

    comments?!

    Be careful when considering replacing a projector fans.

    Most of the fan "noise" you hear with single lens projectors is the sound of the air being moved rather than fan motor noise. Be sure that a new quiet fan can move the same volume of air at the same velocity as the current unit. Get this wrong and your projector might cook itself to death.

    CRT fans are much easier to change as the cooling is (generally) less critical.

    Regards

    My Seleco 400 is working beautifully, I intend to write to the PM requesting that Gordon be knighted for services in the field of calibration. ;)

    The fan noise is a bit of a wrench though. I am keen to know whether anybody here has successfully changed the McRegular fan for a quieter alternative. If so, any advice and recommendations will be appreciated.

    Failing that, if you've not skipped that custom hush box Jeff, wrap it in old carpet and send it this way. I'll square up with you for the courier bill. :)
