The Omni VII has a big heat sink

But no Fan

  So looking through my spare computer stuff found a fan from a old power supply.

also found a piece of Aluminum angle drill  few holes mounted

 the fan.

Next drill two holes on top plate of  the heat sink and mounted the assembly.

the back of the radio in my case was wired for 12 volts from a RCA jack on the radio.

Ten Tec at one time had a kit to make this change.
