1999 996 startup engine whine

Engine

Vehicle Information: Model: 996; Year: 1999; Body Type: Coupe; Total Mileage: 37000;

A previous member wrote in about a whine which occurs for 45 seconds after startup and then stops. I experience the same and it sounds like a high pitched whine - like a plane taking off (nice huh?) I like the sound but I can't figure out what it is. Is it a pump or some sort of startup pressurization? It continues whether I'm driving or not, and every once in a while it occurs for a few seconds at a stoplight. If the car is started again after it has warmed up, the noise does not occur. Thanks for any information you can provide.
