Do I risk destroying the fan if I use a vacuum cleaner on my laptop?
Solution 1
You could damage the fan from spinning it that way. You could also damage many components in the PC using a vacuum cleaner - it generates a large amount of static electricity! You should NEVER use a vacuum on electronic equipment!
The proper thing to do would be to open the machine out and blow the dust free with non-static compressed air. (It's best to hold fans still rather than letting them spin freely for the same reason having the vacuum spin them up is bad, but very few people bother to do this because with quick bursts of air the odds are very slight.)
Solution 2
I have been told that each motor of the PC's fans relies on bushings, that are built to tolerate a certain RPM. Exceeding that RPM, such as when large volumes flow, can reduce the life of the fans. In addition, off-center suction can place a tangential torque on the axle of the fan. So you do risk this kind of damage as well.

To get rid of dust that had gathered near the fan, I put a vacuum cleaner to the air intake (with the computer turned off).
This removed the dust.
It also caused the fan to rotate at a fairly high speed. Quite faster than normal speed, judging from the sound.
Do I risk destroying stuff by doing this?

uxout over 13 yearsIn theory, sure, especially depending on the ambient humidity and just how dusty the damned thing is. I wouldn't worry about it if you're just using compressed air though.

David Richerby almost 9 years@qroberts The static electricity is caused by the cleaning you did with the vacuum before you brought it to your computer. The nozzle becomes charged by being rubbed backwards and forwards over your carpet and from bits of dirt and rubbish rubbing against it as they whizz into the cleaner. Then, when you bring the nozzle close to your electronic gear, *zap*.
