I'm still considering the thermalright shaman as an possible alternative, but I just wished the cooling fin orientation was for external exhaust rather then internal exhaust
Yeah fin orientation is why I chose the accelero S1. They have a new model out now but it looks very similar. I think the vertical layout of the FT02 makes it challenging as well. Heat pipe don't perform well when the hot part of the heat pipe is above the cooling part. The fluid inside likes to be assisted by gravity to flow back down to the hot section. With the Accelero S1 inside a FT02 only 2 of the heatpipes are oriented optimally. The other 2 are oriented poorly. I felt them by hand and only the top 2 heat pipes (the proper oriented ones) were hot to the touch. The bottom 2 didn't seem to be conducting even 50% as much heat as the top 2.
I also looked at the Shaman but the surface area seems to be pretty low. There are 8 heatpipes compared to 4 though. Who knows... I do know that wide fin spacing is important for passive coolers. If the fins are too close they inhibit airflow.
I had also purchased a Thermalright HR-03 cooler from a OCN member but he scammed me and never delivered the parts. Yeah you know who you are, jerk...Edited by Epitope - 1/10/12 at 5:55am
