Hey, Dondan!
I think your semipassive scheme isn't feasible because
A) air always chooses path with lowest resistance. That means air will flow through the open spaces which are plenty in there, not through the heatsink.
B) You can force air to move through the heatsink by some kind of ducts...
I'm sorry that I have to contradict you but Dondan in the referenced post said he used a Scythe SY1012SL12M fan with this cooler.
If there was a cooler that could cool a cpu passively I think there would not be the need for a special cooler Dondan is developing now.
Did somebody try a PH-TC12LS CPU Cooler? It's exactly 48 height and has a gap between the heat transfer plate and the fins. I just wonder if there's enough space to squeeze a fan there?
I think that is a 40d but I am not sure. That is not my camera. An colleague's of mine. Most of my photos were taken with a IPhone 4, and some with a Panasonic FZ2000. You are right, the lens in the photo is a 70-200L, and it was mine a couple of years ago. I sold it to my work mate while doing...
You've got almost 10 degrees already. And you can't know exactly what the temperature on the C7 would be with the CPU no throttling. And there also are different fan speeds? The result is not relevant. I think that you at least are touching your goal if not have reached it already.
Yes, 94. There is no mistake. That is why I eventually ended up using GPU and CPU sensor combined as a source for PSU control, because of the 75 degrees threshold in Asus MB fan control. I've stuck the sensor toughly in between the heatsink and that little black thingie in the very middle...
