*Specs may change by the OEM, be sure to check their website.
You can use other similar fans as long as they meet or exceed the minimum airflow and they do not exceed the current draw and other specs of your stock fan.
You can connect an exhaust fan that does not draw more current than your stock fan. You will find that info linked above. To do this you will need an IEC 60320 C14 Male to NEMA 5-15R Female 10A adapter like this:

DO NOT USE AN ADAPTER LIKE THIS TO RUN AN EXTERNAL AIR COMPRESSOR FROM THE COMPRESSOR JACK ON THE LASER. THIS IS FOR ADAPTING THE EXHAUST FAN TO ACCEPT AN AFTERMARKET INLINE FAN.
