Vapor Phase Cooling Question!!

Ghaleon4

HEY GUYS!!! I haven't written anything in awhile...missed y'all!

I am SERIOUSLY looking into using the Asetek VapoChill Lightspeed Vapor cooling system on a computer that I hope to build in the next year. (Of course AMD hasn't released it yet, but it will be a Quad-Core AMD system...along with Quad-Core/SLI Nvidia BFG OC 8800GTX's).

What I'm dying to learn about, is whether I can cool multiple components using Phase Cooling with a single compressor unit...and if so...would it be difficult to do it with the Asetek solution I mentioned above? Or...if there's something completely different that I should look into? I've looked around, and haven't even found any commercially available evaporator blocks even designed for a GPU. In the end, I want the entire system including CPU, GPU, and perhaps memory/motherboard Chipset, to be Vapor Phase Cooled. Any ideas??

(And I'm NOT handy enough to build something on my own from scratch...)
Thanks guys!

CPU only.

Thrax!! Howdy!!

Are two of these Asetek units required in order to cool two cpu's I wonder?
Thanks!

For anyone who's curious, I've been told from other sources that typically, if you want to run a dual-proc system...it's typically required that you have two seperate cooling units, and it's likely that water-cooling may be the preferred solution for such a system.

Howdy G4,

If you want four cores, it's probably cheaper, faster, and easier to go for a single quad-core Intel processor. That way you only have to cool one chip.

It may change, but right now, Intel is spanking the pants off AMD with its Core 2 series chips.

We'll see what happens later this month with AMD's mega-release. If nothing else I bet the AMD quads will be comprable performance, but with less heat & better per watt performance (altho deep down I hope they rock the socks off the Core 2 in all possible ways)

The way to cool a system with multiple CPUs and GPUs is to liquid cool. Use a low temp coolant (I like Envirocool) and cool the liquid with a small chiller. Finding a cheap small chiller is the hard part.

I would be cautious trying to cool a current quad core cpu (overclocked) using a stock VapoLS. The heatload is too high (easily over 250Watts, check here, for instance a kentsfield at 3.8GHz and 1.5Vcore puts out 267W according to the site).

mas0n

WOW, that is some serious heat. I dunno how reliable the source is, but it's rumored that the AMD Quad will have a 95W TDP at stock.

Now that would be impressive.

Mas0n:
Man, if that's the case, I can't WAAAIIIT for AMD's release here in a few weeks. (Of course, I dunno why...it's not like I'll be building this system anytime this month, rofl). I guess I Just can't wait to see some benchies, and reviews!
Of course, I think I've pretty much decided that my platform will be a Vapochilled Quad-Core AMD on an NForce chipset, with the GPU/Chipset/Memory water-cooled. mwa-haha! Not to mention the BGF (Do I wanna do this, because of the performance, or just to show off the neat cooling technologies???)

lsevald

Thanks for the link Mas0n But I would wait for next gen phase (or get one custom made), the current models were initially designed for single core cpu's, and probably were optimized for <200W (probably closer to 150W in reality, if you consider acceptable noise levels).

The AMD TDP sounds nice, and its 27% better than kentsfields 130W (CPU speed not considered), which is great But if we compare a good kentsfield OC at say 4GHz and 1.55V (which probably is closer to what you will shoot for with kentsfield and phase), it will end up putting out a tad over 300W (according to the eXtreme PSU calc). If we for the sake of the argument translates this over to the 27% "better" AMD core, the AMD core at a comparable OC will output something like 220W, which still is borderline/too much. And the biggest problem isn't bad temps, but the phase change units actually breaking down.

Yeah, I would have to agree with lasse about production phase and any quad core cpu significantly overclocked right now. You would probably be better off getting a custom built single stage system that is using heavier duty components and optimized for dealing with 250-300 watts of heat. There are several people building custom phase that should hold up under this kind of load. But I don't think anyone's production line phase units can handle those heat loads 24/7/365. And like edcentric said, another option is to go the chiller route, which would probably be easier to do if you want to cool processor and 1-2 vid cards to subambient. But it will take a pretty hefty chiller to deal with that much heatload being dumped into it from an overclocked quad plus 2 overclocked 8800's.

My plan was to do what you are proposing with my wife's comp.
Asetek VapoChill LS on a quad kentsfield. Every forum i checked or posted on said what everyone above stated. QX6700 or QX6600 produce too much heat when trying for a decent overclock.

My new plan, eventually, will be to use the LS with a E6600. Less heat, more overclocking possibilities. Can't say what it will do for any future AMD proc's though.
