Sapphire Vapor-X technology in a vertical mobo case?

[waldoh]

Does anyone know or have real numbers on whether the Sapphire Vapor-X technology will function properly in a case like the Raven 01 (90 degree mobo flip)?

Just reg'd to answer this. I have this setup, Raven RV03/Sapphire Vapor X 7950 and it runs absolutely perfectly and very cool, card at 1150/1400 too.

I saw this question, but had no first hand experience. I was under the understanding that vapor chambers worked exceptionally well with Silverstone's 90° tech. Good to hear from someone who can confirm it. Thanks for taking the time to reg. :thumbsup:

Very nice to hear this works well - and welcome both Waldoh and Andrew

I am pretty sure it will not make any measurable difference. From

Vapor-X heat transfer model
Vapor Chamber Technology is based on the same principles as heatpipe technology. A liquid coolant is vaporised at a hot surface, the resulting vapor is condensed at a cold surface then the liquid is returned to the hot surface. The recirculation process is controlled by a wick system.

Heatpipes return the liquid by either gravity or capillary force, and it is clearly the latter in the Vapor-X, so direction should not matter.

Has anyone ever punctured a vapor chamber, to release the liquid just to see how it would work as a dry heatsink? I wonder what amount the liquid contributes, seeing how copper is very good at conducting heat already, surely it can't be too much worse?

I think there was a thread on that in the Cases and Cooling forum. It is not a good idea, the liquid is there for a reason.
