Yup. Just bend the bracket with a couple pliers to get the magnet off.

I retract my statement about the size of the fan, this thing rips! No need for the larger sized fan at all!

All my materials are in, going to put this together tonight. Just thinking about the washer being used. Curious is the washer needed, it is said to be used to shield the field from the fan motor. Won't the magnetic field pass through the washer and still make it to the fan? With the magnets I bought, the field can pass through my finger and attract each other, very strong magnets.

Has anyone tried not using the washer?

Anyone wondering the quality of these fans, I have two that I have been using in my entertainment center for 4+ years with no issues.
One is on 24/7 to exhaust air from around my DVR and the other comes on automatically with my PS3.

I would buy these fans again in a heartbeat.

You definitely need the washer or some ferrous material to shield the motor. If you have disk magnets you could use a flat bar. Or you can space the magnets above the motor some distance using a plastic spacer of some sort. That's how Stir Starters makes theirs. If you're using two individual magnets, be sure you have one with the N pole up and the other with the S pole up.

I bought one of these awesome thermaltake fans from Amazon (free shipping with prime) and was able to convert it into a stir plate with just a single trip to the hardware store.

For all those who are curious, I couldn't get my hands on a hard drive, but Lowes had a pack of magnets for $2.50 that work just fine. I've doubled them up on each side, but it would also work to just use one on each side.

I glued the washer to the back of the fan, but as of now, I am just letting the magnets sit freely on the washer. They're strong enough to hold themselves in place. (I was too afraid to glue them because if they were out of place it would be hell to remove and re-attach them.)

I just took the back grill off completely instead of bothering to cut the wire.

Here's a video of my awesome 'shamelessly cheap' stir plate in action: http://www.youtube.com/watch?v=LN0Xi...ature=youtu.be

As you can see, I don't have a frame or box so for the time I'm using two books. This fan moves really fast, It's way more than I need for a 1L flask.

This took less than 3 hours including ordering, trips to the hardware store, etc. Thanks for the great idea.

This laptop cooling pad may also be an option. Same price point as the Thermaltake. Likely significantly lower quality, but might be a good option to adapt to stir plate duties.

I'm planning to switch my stir plate from the current monstrosity of a project box to something compact like this.
