Silver Cooling

Indeed, it would sound like it improperly calibrated. Have you done a two-point calibration with it lately?

The only liquids that conduct electricity reasonably are liquid metals and water which contains dissolved ions. An electric current passes through an liquid with dissolved ions since ions are charged particles when they move from one electrode to the other. As someone said earlier the only ions in pure water are H3O+ and OH- and those are in very low concentrations so pure water does not conduct very well.

Can you please explain how the pH meter works. To me it looks like it measures the resistance of the water which will measure how ionised the water is, not it's pH as only the H3O+ ion should be measured for pH. Go down to the local swimming pool centre and buy some pH indicator, as the chemical on the indicator reacts to H3O+ and OH- ions it should give a more accurate pH reading.

good to decent PH meters use a glass or membrane cell to measure the pH and it is pretty accurate across a wide range of ion cncentrations.

liquid pH indicator, on the other hand, is usually mildly acidic and in an unbufferend solution very close to neutral pH, the acidity of the indicator can noticably influence results.
 
why do u all think silver would be a waste yea its more than copper blocks but silver isnt worth alot go to your local pawn shops they will sell u scrap silver real cheap all u gotta do is melt it down and make your owne blocks i have around 2 ls of pure german silver from my pawn shop i might have paid $100 for it all thats enough to make 4 blocks so $25 and a few hours of my time for a silver block yea it sounds good to me

You know, you're quite right!

It really is easy to obtain commercial quantities of guaranteed 99.99% purity from the local pawn shop.

Danger Den should head down to their local store right away!

heh........it sometimes makes you head hurt, doesn't it?

besides the raw materials cost, there is always the issue of having a design that works well and the machining equipment to build a block with.
 
Indeed, I could make a copper block for probably $10 worth of materials... but that doesn't factor in the time or effort it takes to design and manufacture said block. I'm quite happy paying DD/Swiftech/Aqua/Etc. 5x as much as raw materials to do that for me ;)
 
Also, for those interested:

"German Silver" is actually the name given to a nickel/copper/zinc alloy that is very silvery in color, and is often used in cheap jewellery

Anyone paying $100 for 2lbs of "Pure German Silver" was getting ripped off in a major way. There is actually zero silver content in "German Silver".

2lbs of the stuff would probably have a actual market price of around the $10 mark.
 
silve scrap is 7 bucks a ounce any of u who r gonna try and fight me on this are gonna loose ive been scrapping metals for over 2 years now dam i even scrap p1 and old p3 chips 25-35 a pound old edo ram has silver in it tell me i cant sell it or buy 2 lbs of silver for $100 please so i can laugh @ you

Silver scrap (being contaminated with impurities) is being sold for $7/oz? After which you still have to melt in down into your desired shape? You're right. I don't think you'll find many people who would argue with you about it.

Me? I'd prefer to just buy guaranteed >99.99% purity silver at the base market metal price, which is presently at $6.80/oz, and receive it all professionally smelted conveniently in bar form and pre-cut to the desired shape instead (for an additional fee).

Once you get the silver purity level much below 99% purity for almost all types of impurities that silver gets mixed with, (and for some types of impurities as high as 99.5%) then you may as well be using copper for thermal conductivity purposes, and paying 1/10th as much for it.

Scrap silver, while useful for jewellery purposes where someone wearing the silver isn't going to notice, or really care, if the silver is only 90-99% pure is a hugely different scenario in which the ONLY reason for ever bothering to going to the expense of using silver over copper in waterblocks is its higher thermal conductivity, and if you cannot guarantee the quality of the silver, then you may as well save your $$.
 
Hmm.. So are you saying that those blocks that Aqua Computer sells for $150-200 USD made of .925 Sterling Silver is a waste of time? IOW, there is nothing but the bling factor?

Yes. .925 Sterling silver has the same or lower thermal conductivity than C110 Copper, which is what most copper-based waterblocks get made out of. Sterling Silver is primarily a silver/copper alloy, but it is the fact that it is alloyed that ruins the thermal conductivity. In almost every single case where the purity of the primary metal is lower than 99%, an alloy of two metals will yield a thermal conductivity significantly lower than the primary metal, and if the primary metal purity is less than 90%, then the conductivity is almost assured to be lower than the lower of the two metals being alloyed.

If the silver isn't at least 99% pure, then it's pretty much only for bling.
 
Layeth The Smack Down, Cathar.

Bling like that in computer systems is just as ridiculous as it is on Escalades. [giant gas guzzling SUV which we pay human lives for]
