What material is the substrate of the circuit board? The goal, I thought, was "smaller, faster, cooler". There are electronics mfg out there that have made a switch to ceramic based substrates to help with thermal management.

water cooling beats this i think, its not too expensive, and allows you to relocate the radiator to anywhere else, instead of right where your CPU fan probably is, or slots.

The Chinese would find a way to make it burn up...

I'm usually an early adopter, but not on this one when it eventually does come out.

I would need to poor over the numbers on this one, and also see some real world results. Sure a graphics cad like this may technically be possible, but at what price and what risk?

Even a few comrades in my line of work are almost wondering if the results so far might have been underclocked? and as a few other of the posters here have infered upon... It also really depends upon the build of the entire computer cabinet as well.

Plus also consider the following... Reguarding use in the real world... It's one thing to run a computer at a location that's cool enough to almost simulate a top of a mountain condition... But under full load for an extended period on a ninety degree day with full humidity.

If it could be made to work then great; it might just be worth the investment and also making room for it.

You plannin on using your desktop outside? Outside temperature and weather factors have no bearing on a computer that is going to be used inside. Unless you don't have AC of course.

Eerrr; no. Not operatng a desktop outside. Although my 10k++ Origin clocks along quite well even while outside.

But for anyone that would be operating a desktop PC **indoors** with this graphics card, then... On a nice summer day indoors with the windows open - one very well might experience some issues.

Makes me almost miss the days in (indoors again) winter where a Pentium 4 used to heat a 20x20 room nicely

I think I may want to swap my summer days for yours. Mine are usually in the 90's with the occasional 100 degree days thrown in from time to time. No open windows for me :D

Sure, if you don't mind losing four slots on your mobo and case

GET READY TO COMBAT THE HEAT OF THIS MONSTER HAHAHA

Now if only I had the money that I just know this will cost (probably akin to 500 bucks), LOL!

I wouldn't be surprised if that added more than $100 to the cost.

Uhmmmm can it keep my drinks cool? lol

You know there are some active coolers that are really quite even at full load and with the proper case with noise absorption material the passive wouldn't be worth it.

Whoa! That a big momma..
I guess if you are going to have a fanless system (and good luck with that), you don't really need a case, just a bunch of meshed panels. I would assume there are cases like that.
I have no idea how you would passively cool the CPU or the power supply, tho.

There are high quality fanless power supplies, and I do believe MPC did an article on a passive cooler good for 100w TDP.

Seasonic has a couple of solidly constructed fanless models in the 400-460 Watt range, as well as hybrids. A fanless GPU is great, however, they still require sufficient airflow through the chassis to operate reliably.

The Corrupted One

I could see this being great if you stuck a silent tiny little fan on it for extra cooling (I don't trust passive cooling.

avatar

Whoa, that's a big momma!

I think some cases like the SilverStone has collapsable base that can hold the video card.

I love the idea of silent PC, and heatsinks are a great choice. But imagine big HEAVY heat sinks on your GPU and your CPU like this. Your mobo would need to be reinforced against such strain, no?

avatar

You could just get a case with a horizontal motherboard mount, or a case where the rear I/O panel is actually on top like the Raven. Thus the weight is supported by the screws that hold it in place.

avatar

Strangelove_424

Yeah, this would be awesome in a Raven or FT02. Not just for the mobo weight, but Silverstone's vertical cases tend to be quiet, and are impeccable for air cooling. The passive cooler here would do great with the AP fans pointed directly at it, and I think you could easily get it to function below 10db when not gaming.

avatar

Chronologist

Actually, this wouldn't be too good in a Vertical oriented motherboard set up. Once rotated, the heat fins become perpendicular to the natural air flow inside an RV or a FT. So instead of getting a clean airflow through all the fins, you have to make do with an inefficient vacuum effect through the interior of the cooler, and the AP fans blowing at the single bottommost fin. Vertical cooling is superior to horizontal cooling, but only if all of your equipment is orientated to utilize vertical cooling. Unfortunately for Silverstone (and me, I had both white and black RV02's and am getting an FT03 Mini) the majority of the market design their heatsinks for maximum efficiency with standard motherboard orientation.

In a regular ATX case where the motherboard is on the right side, isn't the GPU supported by the screw(s) in the back anyway, assuming you don't use a tool-less mechanism?

Pretty slick idea - would love to dispense with the fan noise but not sure this is the solution though. I'll take a "wait and see" until I see some reviews.

Yeah not so sure how well that will work since the heat has to go somewhere and by the looks of it seems as if it goes right back into the case instead of out the back. That is a lot of heat to be transferring back into the case. I suppose if you have efficient air flow through the case then it might work. The air flow through my case is about on par with a turbojet engine so it may work for me. lol!

If it is more expensive than a water cooled unit than personally I'm not for this but then again I'd love a phase-change cooler if anyone wants to donate. :-)
