Just get a 315MHz transmitter module and send it the IR signal. It will work
just fine without any type of adapter. The superregenerative receiver used
in the fans cannot switch on/off at the 38-40kHz rate of the IR so it will
just output the baseband signal as if it had been transmitted that way which
may even be the case if the transmitter switching rate is also low.
Transmitter data rates tend to be less than 10Kbps.
