Static gap design...

Whats the best design? I was experimenting with 1/4-20 bolts, a 6.8 pf 
capacitor and a 7 turn air core coil in the typical tesla arrangement 
powered by a 2500 VAC MOT. Even when cooled by 2 120mm fans turning at an 
insanely high RPM it would glow red hot within seconds. What am I doing 
wrong? Will a higher voltage help it run cooler? or do I just need more 
airflow? Also, can I see the gap "quench" with my own eyes? I notice when I 
add the capacitor and coil to the circuit it gets much brighter and VERY 
loud, so I'm guessing it is doing its job. Any ideas or tips?
