A couple of weeks ago I bought a 22" widescreen LCD for my Macbook. This setup works great except for one thing. I get a temperature increase by 15-20C. When using it without the external screen the idle temperature is around 40-45C with a fan speed of about 1800-2000rpm when I plug in the monitor it goes up to 60-65C and a fan speed of 4500-5200rpm. Under just a little load 20-30% the temperature goes up a lot and the fan start spinning full speed. Which is usually only a problem when I do really CPU-intensive tasks with only the Macbook screen. Is this normal? Is it the GPU that heats up a lot when using an external monitor? I can't believe this is how it's supposed to be. I was planning on buying an iMac first, but people here convinced me that since I was pleased with the MB, buying an external screen for it would be just as good. But this is hard to live with actually. I'm very sensitive to fan noise and the small notebook fan is really loud when it's spinning full speed. Also, when producing music the fan cuts through the music (even when playing fairly loud) and makes it hard to concentrate on the sound when mixing. And recording in the same room is out of the question with the external screen connected. So is this normal? If it is, do you know any solution to it? I've considered getting a cooling pad, but I'm just not sure if it will help at all. Since I bought the screen I can't afford an iMac right now. And it seems to be a bad time for buying one anyway.
