Are they? Well, that suggests something could be wrong with your case ventilation-- perhaps a stuck (or even reversed) fan. I know, it's not as interesting as the possibility that different versions of FreeBSD present different CPU load, but if you aren't controlling for major factors like the case being opened or closed, or using different coolers, then there's little point in worrying about whether your load-testing of the software is accurate.
