At first I thought the same and replaced a better fan, which made no
difference (human feel the noise is reduced to half when it is reduced to
one tenth). I then added a couple of diodes along the 12 V line to the fan
to reduce the voltage and turn the fan slower. This didn't make a difference
either.  I then bought another 5.25" disk second hand (66 MB at US$150) which
is reputed to be the least noisy. The noise has been reduced to half, but
it was still roaring! 
I then bought a 3.5" disk of the same specification at the same price. The
noise has been reduced quite substantially now. But I must say it is still
noisier than ordinary 104 MB SCSI drives.

The megafile30's original drive was a seagate thing and got heated very
easily. People sometimes sticks a very think fan on the drive mechanism
directly,but the casing of megafile30 does not allow this. 

A warining: a 3.5" drive cannot be replaced on the 5.25" mounting.
