Canon 70-200mm F4 IS noisy IS?

Just got my refurbished 70-200mm F4 IS and I am loving it so far. I know I didn't buy it for the IS quality, but in a quite room, it is pretty noisy. It makes an initial click noise when I half press the shutter and then it sounds like gears spinning inside. I've had IS system in the kit lenses and Sigmas and they aren't this loud. I guess I was expecting more from an L lens. Is this lens supposed to have loud IS? or did I get a defective one. Seeing as this is a refurb and has been thoroughly tested, I guess this might be normal?

It's normal.

It sounds exactly like this, http://www.youtube.com​/watch?v=YjZE838TKl8

Sounds fine.

its normal

It's normal, mine sounds the same way.

There's nothing better than a noisy IS!! At least you know it's working

Haha, I understand, but that initial click clack screech sound that starts up the IS motor is what gets me. The actual IS running isn't that loud. I just thought it might be a problem because my kit 18-55mm and 55-250mm are pretty silent on the IS startup. My Sigma 17-70's OS is pretty much completely silent so I don't know why an L quality lens is so noisy on the IS front. But since everyone says it's normal, I'll believe it.

LOL, I know exactly what you're talking about. When I first got the 70-200 f4L IS I too was worried about the IS noise. It is a lot noisier then the other lenses you listed.

If you do a search you'll find that this question pops up like once every other month. Nothing to worry about, just wear some ear plugs so you don't go deaf

This lens has the noisiest IS I've come across - It's normal!

If you look at how it works, it is understandable, that it makes noise:
