Unfortunately you can't funnel air to accelerate airflow as wayne thinks.
The air velocity you can reach is limited to your forward speed unless you've got a fan or vortex sucking air out the other end.
Ok, I have an idea where to put the pyro probe.
As for a fan mounted to draw air across the IC, that seems feasible, it'll have to be a little thing to fit where it will do any good. Jake2far mentioned and alcohol and water sprayer to cool things off. What's the story there? Is it just spraying over the IC to improve heat transfer?
