so, given that the hypothesis is that top down coolers cool the motherboard/ VRM components more effectively, why no temperature readings of those components? Although to make it a robust comparison with tower coolers this would have to be done in a case with a rear fan at constant speed, given that this also contributes to cooling those components.
There's enough anecdotal evidence out there that top down coolers don't cool the MB any better and in some cases actually heat it up (afterall, it's not cool air that's being blown onto them). Given that and the fact that top down coolers are almost always inferior in cooling the CPU than tower coolers, I think this would be a good "hypothesis" to test properly.

I thought the heatsink test procedure on SPCR was open bench?
If so there isn't a normal airflow and every case+casefans combination changes those temps.
yep

It has also been argued that the platform should be enclosed to simulate in-system conditions. If so, other considerations have to be made. What type of enclosure? One with the power supply at the bottom or top? Where should the fan placements and ventilation points be located and what size? Should we add a system fan, and if so, which one, and set at what speed? Going this route may lead to realistic results, but for only one case layout. Also, any extra variables we introduce would benefit some heatsinks while being a detriment to others. For a fair test of heatsink efficiency, we need to eliminate as many performance-affecting variables as possible. For isolating the heatsink, our original, open system setup seems optimal.
