That mobo 2 sensor could also be your voltage regulator(s). They run hot. Direct a 120mm fan around the CPU socket and see if it drops any. It should also change with CPU load...
One problem with passive CPU coolers (or watercooling) is that the components surrounding the socket, most importantly the voltage regulation circuit, don't get the benefit of air movement created by the heatsink fan. While they are designed to run fairly hot, some airflow is generally recommended/required to keep them reasonable. Could also be a bogus reading entirely. :) Greg > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:hardware- > [EMAIL PROTECTED] On Behalf Of Brian Weeden > Sent: Monday, September 01, 2008 12:18 PM > To: [email protected] > Subject: Re: [H] Memory issues (Solved) > (*snip*) > > Here are my temps at idle according to Speed Fan: > > Mobo1 - 102F > Mobo 2 - 194F > Mobo 3 - 106F > HD0 - 86F (as reported by the RAID controller) > Core - 48F > > At those temps the machine is rock solid stable.
