A Rotron Spinnaker 24V blower will just cool a 8877 at continuous 
full tilt, and it's easy to wind the speed up and down if you want 
to control noise levels. In the UK these are an attractive price 
compared with mains powered fans.

There's an article at describing how to estimate 
what to expect from a blower given cage size and speed.
