Rudee,
It isn't a matter of a numbers game. How can one accurately compare heatsinks if you cannot even accurately read the temps?.
For the individual user, accuracy may or may not be important. But at the same time, comparisons of temp, of which heatsink is best, should really be put off until a proper and more accurate way of comparing temp is devised. And not to mention all the temp comparisons where people come in claiming CPU temps of under 40C(including you Rudee, who claimed a 42C temp on a 1.2ghz t-bird. When people post/compare socket A temps, since they are inaccurate, it only leads to confusion.
Not to mention, I have posted this numerous times, do not compare socket A temps. If you're using an updated bios, it gives you a good "rough" idea of what your core temp would be. If your cpu runs fine, and the temp is within "reasonable" limits, then don't worry about it, and don't try to compare temps. When people, yourself included, stop posting both ridiculous temp readings and temp readings in general, then I will stop telling people not to trust the readings.
