Hardware fails. Jaspers are not the perfect chipset. For every person that had one fail, there are more that haven't. No particular model of the 360 is going to be silent.[/QUOTE]
I don't think the OP was asking about the hardware but rather, if the new chipset has improved reliability vs past models. It's a fair question, considering how 360s have a very high failure rate.
OP, we got a Jasper 360 about a month and so far, it's been problem free but Jasper units haven't been out in the wild too long (I think it's only been a few months) so it's hard to say.
The fan and drives are still loud though they're much quieter than our old Falcon model (which was almost the same as our Xenon model). But noise really isn't an issue if you install a disc on to the HD. It eliminates drive noise so all you hear is the fan (which you really can't hear during games, unless you sit really close) and it also significantly reduces load times. Also, it runs a lot cooler... so that should help with reliability.
