It's fairly well established that the thermal sensor on the CPU is considered inaccurate when testing the performance between different cooling solutions.
But has anyone considered finding out how inaccurate that method is? For example, comparing [H]'s method of using a 'thermocouple milled into a CPU' with the built in sensor on the same i7 920. The extra work in doing this is as simple as just opening a program like CoreTemp while testing.
I'm also wondering if the built in sensor is still accurate enough to give the same rankings of each CPU cooler that the thermocouple results give.
The reason I ask this is because I'm trying to get an idea of the difference between watercooling and aircooling solutions. But since the methods of performance testing are completely different (watercooling uses the temperature delta between water and air temperature), I can't have any comparison with the two.
