I am using an Intel Core 2 Quad Q9650 running at 3GHz, normally using about 90% of the capacity of all four cores on a Rampage Extreme mobo. I have been monitoring the temperature for some time and have noticed that in the last fortnight there have been about 4 or 5 occasions when the 'CPU' temperature as shown on AI Suite has changed from about 55C, plus or minus 2C to an almost steady 67C. Reducing the load on the CPU so that each core only uses 5% of capacity made no difference to the 'CPU' temperature.
However, this only happens during the night time. I have now been logging the cpu temperatures for several days using Speedfan and in the early hours of this morning the 'CPU' temperature again moved up to 67C.
These are the stats from the Speedfan log from midnight until 06:25, just before the 'CPU' temperature shot up.
CPU Core 0 Core 1 Core 2 Core 3
Avge 56.8 65.2 58.4 58.4 59.6
Max 59 68 60 62 62
Min 52 59 54 52 54
These are the stats from 06:25 until I dropped the CPU load to 5%.
CPU Core 0 Core 1 Core 2 Core 3
Avge 67.5 61.1 54.6 53.6 55.3
Max 68 65 58 58 60
Min 67 55 50 48 50
These are the stats from 06:50 until I switched the computer off a few minutes later, as this is the only way to get the 'CPU' temperature down.
CPU Core 0 Core 1 Core 2 Core 3
Avge 65.5 40.8 38.6 37.3 38.4
Max 65.5 42 42 43 43
Min 65.5 40 37 36 38
It is obvious that the 'CPU' temperature is not the average, maximum or minimum of the four core temperatures so does anyone know what it is measuring.
Does it mean that my CPU is about to fail?
Any help will be appreciated as I have no idea if I need to do anything about it.
I have briefly used PC Probe II and it shows the MB temp as between 29 and 31C, SB is between 45 and 48C, NB varies between 50 and 57C, and Power between 31 and 44C. The lower temperatures are, unsurprisingly, when the cpu has very little load.
