I am not a turbo guy so I hope I don't get blasted for posting on this forum

The fan switch is set to come on at 240. Way too high in my opinion. I wired a manual switch so I can control the fan myself. You can find the instructions on the DIY section on this site. There is also a BMW thermo switch upgrade that turns on the fan at around 210. I also blocked off the bottom of my cooler to trap the air from escaping. That and the fan helped lower the temps about 15-20 degrees.
