    Which metal has better conductivity ?

    Copper or Silver ?

    And what are the practical problems of using pure silver blocks in a watercooling system ?

    Other than cost obviously.

    silver is better then copper
    and as far as im aware there isn't any apart from the usual but thats sorted with a bit of WW

    Doesn't the silver cascade only perform 0.5-1 degrees C better then then the copper version?

    dunno think its more then that he got like an extra 50 mhz out of his CPU but hey im all for the

    Bling Bling my friend :D

    Yeh the WOW factor is definately one of its major selling points

    Find out the specific heat capacity and the heat conduction speed of both and there's your answer.

    Even though both are unreactive (compared to most metals) i still dont trust a multi metal system, you're just asking for trouble.

    I read somewhere that it was only 0.5c, so its more for the Bling!

    Carbon is far better than either, and even better in its diamond form...

    Someone posted recently about a new alloy using diamond :cooldude:

    /off to search...

    EDIT

    /GRRR... cant find it, I know it is here somewhere...

    Re: Re: Copper or Silver ?


    What multi-metal system ?

    All blocks = silver.

    Rads are not copper anyway ... so its the same as a Cu system right ?

    Specific heat capacity doesn't have an effect on the rate of conductivity of the material. This is defined purely by its thermal conductivity.

    What the specific heat capacity of the material determines is the rate at which equilibrium temperature gradients are reached within the block, however, it is also important to remember that specific heat capacityis given as units per gram of material while the difference in density of some materials, especially copper and aluminium varies greatly and must also be taken into account, as it is volumes of material rather than weights which remain constant when comparing similar blocks of different materials. In the case of aluminium vs copper, copper is much slower to respond to sudden changes of thermal load, resulting in a smoother temperature reading even during varying use.

    Rads use copper piping.

    8-Ball, i know that specific heat capacity doesnt affect the rate of thermal conductivity. :p :rolleyes: and that you have to work in per unit volume cause of density considerations. I just couldnt be arsed to say it in the first place :p

    Oooo Cu-C alloys :rock:

    The SS Cascade gets between .5 and 1c, it depends on how high the O/C is in part. A higher heat output form the CPU helps to increase amount of heat removed when compared to the copper Cascade.

    And I really do wish I could afford a SS Cascade, but then I'd also feel compelled to buy a larger more powerfull pump and a huge rad as well.

    Cost? $400+ USD, ...............I don't think so.

    I was considering getting a silver block made, then I realised that I would have to design one as well ... so I guess it aint gonna happen. :sigh:
