Hello. Just wanted to say how fantastic this program is. It helped me pinpoint issue with my cMP NorthBridge heatsink which I will be attempting to repair on my own before I have the CPU tray replaced. I have contacted the creator as I had some questions and I had excellent customer service. The app has a "light" version available in the App Store that does not have the manual fan control and automated reporting functionality but still is a great troubleshooting tool.
