Your fan is likely not needed. These radios are designed to work with everything the way it was.

As far as a SS replacement 5Y3, it would run cooler, but it would also raise the odds of shorting out the input filter because of the instantaneous, unloaded B+ voltage. Ideally, the original tube allows all the other tubes to warm up so that most or all of the load is present by the time full B+ is available.
