Does the xbox 360 Jasper chip work

Yes, I have an xbox 360 with a jasper chip (yes I am sure it is a jasper) and my 360 gets only slightly warm after running halo 3 for 6 hours straight. It stays much cooler then my laptop or wii and and is the coolest (as in temerature) electronic divice I own. My xbox 360 works very well I have not had lag, freezing, or the rrod.
