Ever had a video card or processor, or power supply fail because of a
fan that stopped working? Plastic fan blades create static charge,
this attracts dust, the dust slows down the fan, and makes it spin off
axis, like an imbalanced car tire. Eventually, the fan fails because
its bearing fails or the coils overheat.. So for want of a metal
blade, you get a dead computer component likely worth 100x the price
of the fan.

Get off your arse and clean it once a year for crying out loud and all
the other dust bunnies inside as well. You probably expect never to
have to ever clean a dslr sensor either.

Problem is a metal bladed fan you be much heavier and put more strain
on the mechanics shortening fan life and it'd be louder.
It's also more difficult to cut & bend metal blades to the most
efficient
shape for the maximum airflow. I guess you could coat plastic blades
with anti-static stuff.
But I think the big problem is safety, child safety in particular.
You have to assume that the little buggers are going to stick things
where they shouldn;t
and metal blades are far more dangerous from that POV.

Metal blades need not be heavier. It can be made much thinner than
plastic because it is stiffer.

Sure about that?

No, my now fairly old D300 is no real problem.

I easily removed any dust from my sensor on my D200, with a puff from an
ear syringe. After many years of service my D300 has never had a dust
spot issue. I never take off a lens when the camera is on. Every time
the camera is turned on the camera rids itself of dust spots.

I did not expect accurate information from Rich, did you?

I guess he missed his chance to get in on the ground floor.

The real problem is not the material of the fan blade, but people
refusing to repair and maintain old stuffs on behalf of costs.

The only people who think the D200/300 don't have major dust issues
are those who have never owned Olympus or Panasonic. Nikons get dust
on them days after their first use, if you change a lens.
