Disclaimer: I cannot guarentee that all of the results are correct, since these are not the results of my own testing. Also, the results were obtained in different systems under different conditions, so they should rather give you a rough idea of the cooling performance of different coolers.
Also, using a different motherboard may result in slightly different temperature readings, since the sensor might sit at a different location.
