I just completed my first CPU Cool Down Test. It takes just over 10 minutes and is about as exciting as watching paint dry but I think it will give users some useful information about how their sensors are working. I'm sure Intel is going to be real happy with this test.
This test uses Prime95 small FFTs for consistency. I was running 4GHz at 1.40 volts with my Tuniq on low speed to create a nice temperature spread from full load to idle.
During testing I noticed that when using the Clock Modulation feature that as a CPU throttled down, my Kill-a-Watt meter would show less and less power consumption. In theory, every step down in power consumption should translate into a lower core temperature. A person should see the Distance to TJMax increase at each and every step going down in the chart.
Here's how my test looks on my E8400 that doesn't have sticking sensor issues at normal room temperatures:
I think a processor with sticking sensors when running this test is going to get about half way through it when it will be very obvious that the sensor has stopped moving. If the power decreases to the CPU and the CPU keeps reporting the same Distance to TJMax then that is going to be an easy way to see that one of your temperature sensors is stuck.
Hopefully within the next 24 hours I'll have a version ready for download.
Anyone out there with some stuck sensors that need testing?
