Riverjamie lol welcome to the joy of owning a bmw and e39.
This is what you are in for me thinks if your aux fan resistors has gone to get a them front end dis assembly is required.
The fan in the e39 is on a 50a circuit which means that the stock wiring for the e28 aux fan will be insufficient as it is on a 25a circuit.
Sorry had to put this last dis assembly pic of the front end in as the guys just love my blue bmw work shoes first question that lower hose will not get anywhere near as hot as the upper for awhile.

I have 2001 530i bmw i plan to convert my clutch fan to elect fan the vendor told me that the elec fan will come in as push type but i can change it to pull type which one is better i also plan to leave the aux fan located in front of condenser because the fan is still working when a c is on what do you think.
I wanted to be able to have the fan run on a high and low speed so i planned to use the resistor set that came with the electric fan.
This fits your.
I replaced the resistors on the fan and the temp control sensor on the radiator.
