sorry for the resucrection, but:
nissota: I haven't gotten around to finishing my review. The SPAL controller still rocks - No overheating issues and that is with an OE replacement rad. Granted, no fan controller will prevent your car from overheating if the rad or fans are inefficient (sp). IE, lacking in thermal conductivity or actual air movement. What the controller does is manage temperature change and variation, and the SPAL controller does a very good job at that. If i was lacking in either of the above items, then running the fans all the time wouldn't help at all. hope that clears up your question.
