Intel "stock" Watercooling Solution by Sanyo Denki @ Toms
 

Interesting article on a fully sealed watercooling system by Sanyo Denki at Tom's
http://www.tomshardware.com/cpu/20041015/index.html

A possible response to Apple's moves towards water cooling?

no, when the market is percieved as large enough these products (will) appear
but a C/W of 0.37 indicates some ways to go
our H2O-120 kit has a C/W of 0.23 with 3dBA less noise - but it is not a single module, and much more than $99

I would hold judgemnet on this device untill someone else tests it.

Tom's methodologies always seem (IMHO) to be lacking.

Something's gotta give though. Web reviewers are reporting that the Prescott 3.6s run so hot that they constantly throttle down to performance ~ 2.6GHz northwoods in CPU-taxing apps (scientific stuff for example). Intel oems are going to have to find something cooler than the retail hs but not any louder if they are going to deliver the performance consumers want and meet OSHA/EU workplace noise level limits. Water starts to make sense at this point doesnt it?

Dunno. What does it cost intel per sink for their current stock ones? A few dollars? It must be cheaper to go to a design like the Thermalright XP120 and a 120mm fan than to do a water cooling system of any sort.

A C/W of 0.37 is much better then 0.51 even if it isn't optimal it is an improvement from stock HS...
At least it isn't worse...
What is the C/W on that heatsink is? I can't find any comment about that on thermalright's website

Overclockers.com rates the 120 at .16 with a high speed fan and .28 with a much lower speed fan...

Cool unit, but does this mean intel has given up on making a cooler chip???

a CW of 0.16 is great but your fan will scream at 59 dBA :evilaugh:

I think the thought of mind with this product is good enough to work and not the best.

I wouldnt take that C/W as gospel, really. After looking at it, it seems pretty dubious. As their articles say 'Not comparable with others'.

(P4 diode? come on....)

From thread

"How do you compare this concept with the recent posts on low-end/low-noise/integration?

Many times in this forum the advantages/disadvantages of aluminum vs. copper have been discussed, but is this more frequent use of aluminum (Apple G5 also) in such setups the beginning of a trend?

Will it make a dent on copper WC systems manufacturers, or it will be like a "stock" cooler vs. a "heavy-duty" cooler relationship?"

Stock vs heavy duty
Aluminium is lighter, cheaper and easier/faster to machine than copper, and will always be the first choice in 'cheap' cooling.

59DBa doesn't mean the same thing as it usually does when it's measuraed at 8", Madhacker. The 0.16C/W is merely the results on a P4. It's the CPU case temperature, not the die temperature. I think it's accurate (for what it's measuring) although meaningless. I don't think that WC has a place in mainstream desktop computers, as something like an SLK 800 is good enough and cheap, and will be good enough for some time to come.

Also, "machine time" is not all that relevent, when what they do is cut up plates and solder them to the base.

I would not compare JoeC's C/Ws to anyone elses for several reasons

I suspect the Sanyo #s could be fairly accurate, there are industry (Intel) procedures - and for a few even hardware

their advantage is the ability to intregrate, and the capital to mass produce - a very fancy fan/bracket there

joemac, for sure - they have a specific price/performance point
and probably an OEM case its going into
I wonder how it 'got out' ?

Probably the same way as Apple's G5.

which means there is another OEM WCing box to hit the street
?
whose ?

Wild guess: Sony or Dell

hmmm
if I had such a product Dell would be a good target

On the other hand Apple approach towards WC seems (to me) to be a more consistent one (long-term?- if these words still have meaning in IT)) compared to the Sanyo Denki, which rely solely on Intel plans (not known for their accuracy).

So the question is: what kind of "move" is this?

what makes you say "on Intel plans"
I think the article used a Prescott as an example, and speculated about Intel
did Intel provide that module ?

maybe toshiba or fujitsu? They've been dabbling with wcing for a while. The japanese PC market switched to sff long before us users; maybe water becomes required sooner in the lil cases..

Isn't the emerging BTX form factor a move (by Intel) towards better cooling while keeping the noise down?

can't picture this in a small case, its considerably larger than 120mm - thats the entire backside of one of those cases

Got this link from another forum:http://sanyodb.colle.co.jp/pdf/sanacemc_li_e.pdf

I'm not saying its their design, but I think Intel had a part in creating this thing.

Based on the short tube lengths, (assuming thats a final product) I would think this is designed to be front mounted in a BTX system.

My guess is also Dell.
