I'm pretty sure that doesn't matter. I ran prime 95 for a half hour. No amount of variance from "average" versus "maximum" would account for these variances after a half hour running full blast.The reason for the different temperatures may be found in the individual software's settings. Check your settings and if there's an option for showing either Minimum, Average or Maximum temperature, go with either average or maximum. And make sure that it's set for the same in each program.
