OCWC Silver Polyblocks...
 

Has anyone tried the newest version of the polyblocks?

The main fear is a battery effect and rapid oxidation of the silver metal.

Perhaps, something to cure the oxidation process is an old method for cleaning silverware: Baking soda (sodium bicarbonate) dissolved in water and aluminium foil.

OMG Chip sent me some temp specs of his silver blocks!!

WHOA. I want to get 2 for the DH3 write up in a week or so, but we are dealing with pure silver so the stuff isn't NEAR as cheap as Copper.

There is NO greater battery affect then with Cu. So using some water Wetter will Null that out.

I forgot about that process....Its called a sacrificial anode. You use another metal that is higher on the oxidation table to use with the silver. This way the aluminium is oxidised instead of the silver.

Pretty cool stuff! They use this on boats and in other applications as well.

Try dropping a piece of zinc in the reservoir...

thanks for the replies,

Joe, i'll be waiting for that update the silver polyblock. If it is what that pic you posted is like, i'll be in the market for one.

can someone please tell me how the water is channeled through the polyblocks. From just looking at the pictures, the poly block looks like it just has a large section taken out so the the water will just "pool" on top of the metal plate.

thanks in advance,

The water "Pools" but its constantly moving, and moving pretty praidly. it swirls.

it removes an incredible amount of heat ooff the plate. Thats why most new water block designs ( most of which havent been released fo rpublic view yet) are all using the Pool type design. Chips seem to perform just as good at half the weight!

I just ordered my new "silver" poly block last night.

I wish I had a tiny little boat to take a ride through the polyblock & tell ya all about it, but in it's absence.... over the course of a year+ testing of over 50 waterblock designs, the swirling pool is the most efficient in any given material.

While conventional design practices dictate that a forced path covering the most exposed surface and distance within a waterblock SHOULD be the most efficient especially if the inner surfaces are roughened to disrupt laminar flow, practical application and experimentation have shown that "it just ain't so"

The most efficient waterblock designs I have tested use the swirling pool design and have the lowest metal:water ratio possible while maintaining sufficient thickness and rigidity on the contact surface to keep from warping and losing or diminishing contact with the cpu.

In this video http://www.overclock-watercool.com/waterblock[1].asf you can see that the water doesn't pool. It forms a quickly spinning whirlpool that impinges upon the internal surfaces repeatedly before being gradually sucked out by the waterflow.

only sterling silver will oxidize/tarnish, pure silver will not do this under normal conditions, though it is best to keep it out of direct water contact

Umm Water cooling - Silver.... <in Homer voice> "DOH"....

I just ordered my silver polyblock. I have a question though; I can't find water-wetter in my area (SW VA). Is just using anti-freeze ok?

I believe OCWC has Water wetter up on the site now. and lower priced then some other sites that are selling the same stuff, just re-marked into other packaging.

Thanks Joe, I ordered me up some.

what about silver plating the copper bottom of a poly block? it would keep the price down but bring up the thermal conductivity

I'll give it a try sometime in the next couple weeks.

come on fellas, the heat is passing THROUGH the material.

For a comparison of cold plate materials and thicknesses see:

Hey Chip/twocpu, I didn't know where else to put this. I have sent you repeated e-mails and I haven't gotten a response. Are you not receiving them, or is there some other problem? I apologize if this is in the wrong area.

Just sent you an email... haven't seen any from you that I can find under cheapdog

Thanks, I got the e-mail. Something must be wrong w/ either netaddress or hotmail. I appreciate the help.
