Fan and ac to dc adapter

hey all, im using a computer fan to cool things down but the one I currently have wont be able to move enough air in the summer to keep things comfy so i was wondering if i could use this fan with my old 12v ac to dc adapter? appreciate any advice. ive included the links to the stuff i have in the post.

the fan doesn't state the draw but the 12v adaptor puts out 500 ma & I have never seen a pc fan draw even 1/2 that so you should be good.
