Everything is well explained in the original thread, in regards to setups etc. The reason the temps are so much better is because the ambient temps today are >10 F lower than when I did the rest of the testing. Underscores some critical elements--when talking about the top tier of heatsinks, were are talking differences of 3-5c under controlled circumstances. Other factors like ambient temps, case air flow can easily overwhelm these differences.

ps. I live in Boston--no AC. Day before yesterday during the main testing it was a sweltering 90f (32c). I typically do my testing all thru the afternoon, or all thru the middle of the night, to have consistent ambient temps. This afternoon, its only 80f (27c).
