Well I guess I can show you my new block :)

[Cova]

I think I might need to get you to make me one of those for the system I'm planning on entering into the next Fragapalooza case-mod contest. Send me an ICQ some time if your interested and we can chat about materials/pricing/shipping/etc. ICQ# is 1577971

And in a few months perhaps get you to make one or two more when I upgrade my main workstation - I'm not sure yet whether it will end up as a single Athlon64 or a Dual Opteron though, depends what boards and chips end up costing me.

"Luck"? Seems to find those most often who work both hard & smart.

"Success comes to those who hustle wisely." Don't remember who said that but I think that applies more to you than lucky does.

You deserve man. Congrats

Be interesting to see how much differance it does make. What grade of copper is your block made of you're using now?

[morphling1]

Cova what about msm I don't have icq installed.

Thanks for those word, Blackeagle. It's electrolitic copper, I don't know exactly how pure it is, I'll ask next time I'm there buying material.
I'm also very interested in what difference will occur, not much I believe but there should be some.

[Blackeagle]

That silver block combined with a 13x multi. should offer you a fair boost to your already amazing O/C.

[BillA]

come on fellows, run some calcs
postulate the thermal 'resistance' due to x thickness of Cu;
then calculate the difference due to the decreased resistance of Ag

account for all of the real deltaT between the CPU and the coolant;
of interest is ONLY that amount between the face of the bp at the TIM joint and the bp surface in contact with the coolant

morphling1 may well measure 'something'; but there are so many other variables a great deal larger than the change, that no conclusion could be possible

BTW, I have 6 Ag wbs; no silver bullets

but silver is a good looker for sure

[morphling1]

Bill is right. Heat conductivity plays smaller part in overall heat transfer on this block forced convection is more imporatant, and in that small part the difference is less then 10% so overall much lover than 10% improvement
But at least it won't tarnish

[Cova]

I assume ya typo'd and meant msn - I don't have that, just ICQ

Oh well, we'll do it the hard way, just e-mail me. rob at baumstark dot ca.

As for the whole silver thing, I'd love to have a silver one but I think it would cost more than I want to pay. It's almost worth it just for the no-tarnish though. Also makes me wonder why we haven't seen gold-plated HS/WB bottoms yet. They do it to the ends of virtually every audio/video cable it can't be too hard/expensive for a thin layer. And with the properties of gold it should both prevent tarnishing, and perhaps be soft enough that with a high-pressure hold-down you wouldn't need any thermal-grease. I think gold also conducts heat better than silver too (I'm quite possibly wrong on that though) which wouldn't normally make any difference at all at that thickness, but if it was soft enough to BE the TIM then it would make a damn good TIM.

Edit:
I'll try and hang around in pro-chat when I can today too, though I'm stuck with the java client for now and my work firewall likes to disconnect me randomly.

[Skulemate]

With a molecular layer of gold on the waterblock, you'd never notice any difference in cooling. Sure it wouldn't corrode, but that's basically it.

[N8]

I vapor plate (vacuum deposition) metals all the time. Aluminum, copper, silver, gold, nickel, chromium, etc. The thickness is typically less than 1 micron. Copper and gold do not stick very well (as in they are easily rubbed off of most vapor plated surfaces.) I have been tempted to coat a heatsink base with copper, gold, or silver and use this thin coating as the TIM, since it is a soft, flexible coating. The only problem is that I have been worried about it flaking off over time and then shorting out something. There are ways to prevent this, but it is a lack of time issue. The other thing is that you HAVE to have both surfaces absolutely flat (since the TIM would be 1 micron thick or less), AND mate together flat during the clamping process (no tilting or twisting.)

One of these days......maybe when we get a sputter deposition machine. I would be able to get better, and thicker layers.

BTW, silver does tarnish over time.

[Blackeagle]

milled the silver block yet? Pix & update?

[-J-]

wouldnt the gold be less efective than copper transferring heat??

[chewyboy]

I hope you dont mind a bit of *cough* *cough* imitation of your block. my 1/16" bit went bye bye so for the first one making sure the slots were in the right place and everything i just made the channels 1/8", the one that i will actually use will have the channels corrected.

[morphling1]

Blackeagle, no silver update yet, I hurt my right hand today, won't even talk about, it was so stupid. So I can't realy work much.

-J- yep gold would be worse then copper.

chewboy, no problem

[lukasz70]

-J- yep gold would be worse then copper

isnt gold the best material for heat dissipation? thats why the Mclaren F1 has a real gold (not plated) heat shield, and thats why DD now has a 24k gold plated rad http://shop.store.yahoo.com/pcpowerz...ngolxtrem.html

[dima y]

I think the rad is plated with gold for some bling bling more then anything else

[lukasz70]

thats true, that what i though as well, but it really seems like a waste it costs $100 !!! :shrug:

the mclarenF1 thing is true though

[Blackeagle]

Sorry to hear you are hurt Morphling, I hope it's not to serious.

[Blackeagle]

How about a update Morphling1? Have you made the silver star version yet? Do you note any perfomance changes?

Pixs?


What type plexi do you use polycarbonate or acrylic? Thickness used?

[LiquidRulez]

Yeah morphling.....we want updates man!
Youve got us all drooling over this silver block, so we want to see it happen.

I think he have been busy with healing his hand and make my and others wb's.

[Blackeagle]

Brezjnev,

Welcome to Pro Cooling !

I think we all want to hear more on Morphling1's block, I know I do. It's not just the silver block but any data from anyone on how well his block is doing. Considering his outstanding O/C of that XP1700 I'm thinking it had to be more than just the chip. His O/C is 200+ more than any others are getting with water that I've seen. And I notice that the White Water has yet to score any such O/C's, and there are over a hundred now out to customers.

Have you received your block yet? Share info with us?

edit: And I'm sure you are very correct that he is very busy. I imagine many are sold on his design due to it's plexi top, micro channels and his High O/C with it. And if the one sent to BillA tests out high performing he'll have even more orders.

[morphling1]

Here I am
Update (damn I don't have a digi cam) I started working on silver block today, I had to make few copper ones, before I thoroughly clean my machine, and prepare for silver, don't wanna lose to much cut offs, so I also made so holder for vacuum cleaner to collect them Block will be finished tomorrow. Silver is realy fun to machine very similar to AL maybe even dryer so nothing sticks to the tool.
Breznjev block was sent on Tuesday he should get it soon. N8 block was sent last week but he still hasn't got it, it takes a little longer to get to US. So he will also know very soon how block perform, he also have dtek spiral so it will be good reference for comparison.
As for the tops I use 15mm polycarbonate... something I forgot blocks

[bigben2k]

Similar minds think alike... I'm going for 1/2" polycarb top.

[Blackeagle]

Look forward to hearing more in a few days. Interesting that silver machines so well.

Have you given thought to a name for your block. To fine to remain nameless.

[morphling1]

Ah boring me it's MK4 the succesor to my other blocks 1,2,3
