How should I attack this fan?

[shilala]

The model number of this fan is odd. The closest I can come to the specs on the fan are here.
The differences are that this fan is 12V-475mA-5.7W.
There is a note on the fan (10-14.5VDC)
I'm hoping to use it in my htpc, throttling it down with my fan controller.
Any thoughts? Any alarms going off?

Attack your fan with extreme prejudice!

Stick a pencil in it when it's going top speed.

I hope you're not going to attack it enough to set off any alarms :Q

dip it in water while running

I've got to get it running before I can stick anything in it. I have a spare just in case.
These fans are monstrous. I'm scared of them.
My worry is whether I'll be able to throttle them down far enough without burning them up.

Ooh an attack thread!

I found the neatest way bar none to take care of those little devils is with Nitrogen. Set your regulator to about 900 PSIG. Make sure your fittings and valve can take this kind of pressure or you may wind up like the guy that thought LA was LAX but bleeding.

The escaping gas will propel the blades at great speeds often exceeding 120,000 RPM. This generates tremendous centrifugal force and causes the blades to fracture at the attachment point on the hub. CAUTION: too little speed is bad as the bearing will displace and the entire hub with blades still attached will likely rip out and take off with enough force to cause serious injury to living and non living objects. Blast it hard and make the blades fly out. These can do damage too but not on the scale as the hub and blades.

The start up wattage is probably even higher that the posted amount. Hang onto your power supply.

5.7W is nothing - a 92mm Tornado pulls 12W

i'd say a large hammer would work quite nicely

I soldered a tail on it and it doesn't like to start under the fan controller's power. If I give it a spin it'll get going.
If I run the controller all the way up it'll start it easily.
I have the - lead right, but I think I have the other two leads switched.
I'll swap them and see what happens...
Nothing happened.
I'm back at step one.
It doesn't seem like it'll be a problem. I'll start looking at how I'm going to control it.
I think I'm going to make a desk fan out of the other one.
