do not overclock an 5970 if it is air cooled, unless you have a room airconditioned, the have a tendency to overheat, and never put 2 5970 next to each other unless you watercool them, putting 2 5970 next to each other will overheat them really bad, leading to very poor performance.
On the other hand the 5970 is a wonderful card for overclocking when water cooling, it will overclock very nicely.
In regards the fan speed you probably have a bad bios, flashing it will fix it, but be extremely careful it is a risky process.
It it were the fan it would make a huge noise and spin very slowly, the noise on a bad fan is variable, and wobble a lot, a good fan will only rotate and the noise level will be constant.
