You have an interesting problem. I hope you figure it out. I have
never used SS relays, but I can't image they cause spikes and other
anomolies that would kill a simple AC motor. Is the relay rated for
inductive loads?

I can't be bothered to study SSRs so I just speculate... Could it be
that the ones you use just deliver one polarity of AC instead of both,
like a rectifier? Resulting in a DC component which the fans do not
like...
