Is it true that the AMD cards control automatically their fan speed according to the temperature? I had set my fan speed at 95% of the maximum but a friend of mine said I shouldn't do that and I should leave it on default settings because there's something in the video card BIOS which controls the speed of the cooler.

I had it set to 95% because this video card was and still is very expensive and I don't want to risk burning it due to insufficient cooling.

Running it at almost max speeds at all times risks burning the fan out instead. Either use default bios values or create a custom fan graph using MSI Afterburner so that the fan runs faster when temps are high and goes into nice quiet breeze when temps are low.

To answer the question, YES, the card controls the fan speed according to its temperature, so the best you can do is leaving it at automatic settings.

Fan speed control is for geeks who feel a giant epeen inside their pants whenever they can control something on their computer. However you chenge it, it will be worse than what the engineers set who designed the card.

Most cards have some kind of fan control built in these days, and usually you can just leave it alone.  It'll ramp up when temperatures increase, and ramp down when the card is idle.  That will often give you a decent balance between noise and cooling, unless the thermal profiles the card is using happen to be screwy... like with the recent 290's.
