Nice 'review' I guess you could say.

ThanX

Notice the spread between full load temps from 90C to 64C. The in die diode does not lie. If this was a socket thermistor based review the temperature differences would be so compressed the HSFs would all be grouped together with just a few C difference.

I don't particularly trust it cause they didn't measure the ambient at the hsf. The just used the room temperature. Since temperature varies rather drasticly throughout a given space, I think that it is rather necessary to measure the temp about an inch away from the hsf.

They did take measures to control it...but temperature is difficult to control at a spot other than the measuring point of whatever thermistor you're using. It's not something you can control, so you should remove it as a variable at all by measuring it. And it WILL vary, as that is just something temperature does.

Wait a minute. The tests were done in a controled 35C constant temperature environment. The temps were both measured and controled. For the average user with a 25C ambient don't you think a 10C increase for the case temp is about right? I really think they were on the low side. Just look at some of the case temps on the forum when new folks ask for cooling help.

In any event, the in die diode is far more accurate than any other method of measurement as it reads the temp in the core of the chip. Notice the wide range of temps for the various HSFs? This is reality. No compression from measuring via a secondary heat path.

So, would you guys buy off this test,? ...as I'm gonna buy something today:)
..., and would you still go with the SK6, Glaciator, or the winner of the test the Dynatron DC 1206BM-0

It's sad that there were no big name coolers in the test. If there were, I would say yes as this test shows a greater spread between various HSFs than any secondary heat path based test. A Glaciator or SK6 would be good choices if you are going to buy today.
