Hmm. I was thinking of the Raven 1 and 2. Raven 3 . . .
I think I would roll up some towels or something, make some soft tubes to lay the case on. That would leave space for the left grill to breathe.
And yes, leave the bezels on. Leave everything on that is on the case when it is standing upright. Remember, the purpose of the exercise is to compare the cooling power of the heatsink in two positions.
I recall an unanswered question: wicking. When the lowest part of a heatpipe is the bottom of the U, then gravity pulls the liquid phase of the working fluid down to the part of the heatpipe that is closest to the cpu. It is then vaporized and ascends the arms of the U to where it will surrender its heat to the fin stack, precipitate as liquid, and fall back to the bottom.
When your case is upright, the heatpipes are more like a C with extended arms. Gravity pulls the liquid phase down to pool in the lower arm of each heatpipe. In order for the liquid working fluid to reach the hot part of the heatsink, it must travel there like hot wax going up a wick - this is why candles work, BTW.
If wicking doesn't work properly in the heatpipe(s), the liquid phase will stay in the lower arm of the C until heat from the cpu travels down the arm by conduction and then vaporizes it. Only then will it expand to go through the heatpipe to release its heat and precipitate and fall.
Other users with earlier D14's said they were happy using it with its airflow pointed upward, using i7 9xx's and i7 8xx's. From that I gathered that wicking was working, and orientation didn't matter much. But that was then. Maybe now it's not working so well.
It just dawned on me that one could mount a D14 in your case, oriented sideways, with the heatpipes oriented horizontally as in a normal case. In that situation you would mount push and pull fans sideways as well, with the fans on the bottom and the top with the inter-tower space running from the bottom to the top fan. It would be weird, and only doable with ziptie screws (see my sig), but it would be a different orientation.
Well anyways, in that case, which is better? Having the case standing normally with the heat pipes facing sideways or putting the case on it's side. http://www.tomshardware.com/forum/19...al-orientation <-- States that it doesn't matter due to the wick.
