Well the duty cycle depends on the diode and the power.
Also that is an awesome hardware store. I don't have anything like that around me.

I'm pretty sure even with a 445 running @ 1.5A you can run it continuously with that fan.... though I'm not sure how much air those fans move. You should get a good 15-20 minutes out of it assuming that fan doesn't move a lot of air... Pretty much more than you ever will need.

With that and a 445, infinite.

Just make sure you use some good thermal paste and you machine it well.
