They are flattened, Neil, It's hard to see it from that photo, but they are. Every Ninja's heapipes are flattened similarly. Where they differ is in both the bottom copper base and the upper 2nd Al HS. And yes, I agree with cmthomson, that AL heatsink doesn't really do much; it can't.NeilBlanchard wrote:I marked up the photo you posted and I pointed to the round heatpipes that do not appear to be flattened. They are the upper set when it is installed on the CPU, and it would appear that very little heat could be transfered to them. Especially, since there is no solder at all on the Rev Cu, which is more than a little surprising, IMO.
Anyway, the NinjaCU is still a good performer, even tho it doesn't match the old sample. W/ Nexus 120/7V only the TRU120E and the old Ninja clearly beat it. My main issue with it is that the clips don't seem reliable given the weight, esp. given the other stories here of tension sag over time with the light standard Ninjas,
In comparison, the Rev B sample isn't even in the same ballpark. That's the one which really has problems. 24C rise at 12V and 31C at 5V?!
