I put this in, from a 1.9 which kicks in at 88c I think.
The fan switch is as simple as fitting one of these

It has an opening closing temp setting of 88/80 vs the stock 90/85. Over on BF there is a lot of talk of fitting an 80c thermostat aswell but I don't think this is necessary - some people suggest it is detrimental but tbh I don't have a clue either way
I don't have an aux fan though so I think I would need this this http://store.bimmerworld.com/bimmerworld-e36-3-series-electric-fan-conversion-kit-p1450.aspx
