Max temp

2011-08-11 23:28:06

Posted by: Fedor V. Kukhta

Core Temp Utility says, that max operating temperature of T5450 is 85 °C.
In a real laptop (Acer Aspire 7720G) under burn test the temperature rises to 80-81 degrees, after which the fan speed reaches a maximum and processor begins to reduce its frequency.
Heatpipes and fan works good, thermal compound applied.
When the processor was replaced with T2370, frequency decrease occurred much later - at 92-95 degrees.
