Stock cpu cooler. What do you use it for?

emergencies...

like for instance h80i dying on me (which mine did)

:(

Sent mine to the knacker's yard for scrapping

This.  And it has come up for me as well.

Best use for the stock I have ever seen. 

My friends use them for their weed plants so I give them to them.

I built myself a tiny computer with an old laptop mobo, but I'd lost the tiny cpu cooler. So I did some mods to the cpu cooler and it fit like a glove.

Paper weight, and a Frisbee when the time calls for it
