My car has always had a little over heating problem. It would never dangerously overheat (hottest it would get is about 215) I am going to be taking it on longer drives on a more frequent basis in the next month so I decided to replace the clutch fan with a mechanical flex-a-lite fan. The temp is great now (stays at a steady 190) but after about 2k rpm all you can hear from the car is a ridiculously loud fan. Has anyone else put a mechanical fan in their car and had this problem? and any ideas how to lower the sound?

 

You should have replaced the clutch. The goo inside the clutch looses its grip when it gets older and allows too much slippage.
