Baking GCN - The card with no fans

[joshhedge]

I wasn't using the specific heat of water.

I was using the heat of vaporization of water as I was planning on having only the vaporization of the water as the primary heat dissipation method out of the system.

I see, but where are you planning on the water vapour going? Will you be condensing it back into the system? Either way there will have to be heat transfer to the surroundings. As a chemical engineering student, I don't believe vaporisation to be the most efficient form of heat transfer for this though. You're best off having the radiator next to a window, or an area with good air circulation and keeping the system in the liquid state.

Because BTX was an attempt to make ever-hotter CPUs work, instead of being an overall improvement. You have to get the somewhat rare inverted cases, to do it w/ ATX.

Or you could just turn your computer upside down. Just flip the DVD/BluRay drive over. You're in business.

I don't know why GFX cards have been facing downward for so long. It's stupid in every metric: GPU cooling, fan longevity and circuitry protection.

What are you talking about? Having the GPU on the top would just make it share hot air with the CPU. GPUs should have their heatsink on the left side (opposite the CPU) with the fan against the side of the case for fresh air. ITX has been getting it right for years. :biggrin:

These cards are viable, you just need reasonable airflow. For extra insurance, a slow spinning 120mm side fan really helps, unlike blowers which essentially show zero benefit from side fans.

Even a 500RPM variant will dramatically reduce temperatures while adding essentially nothing to the noise floor.

As for case orientation, the Raven cases do it right. There's no air sandwiched between parts as each has a direct path of air which is evicted straight out of the case. The only improvement I can think of is to put the PSU flat on the bottom of the case with a dust filter, just like traditional cases do it.

But, that means you need even more fans for a job that one fan should be capable of (cooling CPU+GPU). One big fan could handle it all, if the CPU and GPU shared airflow space.

I would have been good to have more temperature testing, and some info on the case airflow setup. Maybe SPCR needs to review the card?

Oh man, the Raven 4 is just gorgeous. And like you said the only con I've found is the PSU on the top, everything else is just fantastic.

I AGREE a slow moving fan will fix this card for low cash. this fan

http://www.newegg.com/Product/Produc...82E16835200067

on a 4 pin mobo fan jack can run at 600 rpm.
you won't hear it and your gpu will be quiet.
it can be attached in various ways. you can even get fan grills for it.

well under 20 bucks to cool it.

if you get some nylon screws and nuts to secure the grills it is about 22 dollars

those screws listed are long so you can add extra nuts to act as levelers should allow for an easy jury rig.
