I have found that alot of european cars run the fan quetly when the accessory is switched on with the key in the ignition barrel.
This can be a little noisy and can also run the battery flat sooner rather than later.
In many/most cases I have found that this is simply not required and in my case, when it comes to car audio sound quality competition judging, it's down right annoying and intrusive.
I have found a clean and neat way of changing this so that the fan only comes on when the key is in the on position that does not ruin the fan motor mosfets.
I have pics and can post up a 'how to'.
Anyone keen on it?
