I'm sorry to see that my (quite bold) statements are countered with a sense of hostility. Maybe I'm not putting my thoughts into words decently. I have the idea that all heatsinks are tested with: 1) no ambient (relative to the cpu-heatsink) airflow impedance 2) 20°C ambient temperature 3) horizont...

I disagree that the results aren't useful. The heatsinks' relative cooling capabilities are not going to change unless you choose the wrong ones to use in the wrong way -- ie a topdown squeezed too tightly in a narrow case with no room above the fan. My motivation to make my previous post came from...

Another problem with this methodology is that the heatsinks are tested in the open air. But since that's a different way than most of people will be using their heatsink (in a case, mounted vertically), this creates unrealistic conditions, which can alter the results in ways that are irrelevant to m...
