I agree with you that i't unlikely that it's a fundamental hardware problem (like you're getting no air flow) if Linux still reports sane temperatures. But it seems quite reasonable that somehow temperture reading broke for your hardware when you upgraded. Two easy ways to settle the issue would be either to get a thermocouple thermometer, put the thermocouple in the case, and see exactly what happens with the case temperature. Another easy way to settle it is to get the voltages being returned for the temperature sensors as opposed to the reported temperature. If the voltages are the same under the two OS's, then it's definitly a reporting error. :-) Take care, Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
