    Effects of CPU cache size on total system performance?

    Is CPU power draw/wattage linear with CPU usage?

    Unfortunately, semiconductors are not necessarily ohmic, so they don't follow Ohm's law.

    Is CPU power draw/wattage linear with CPU usage?

    I don't really get what you're trying to say. Watts are watts, energy per time unit. 100W power draw by the CPU equates to more from the wall socket only because of inherent losses from inefficient voltage conversion. Watt = unit of power Amp = unit of electrical current Volt = unit of...

    What about using fuelfilters in a waterloop

    I figured- I haven't held one of those in my hand in a while, but I think that type might even have some kind of steel framework inside of it for the paper element.

    Machining my own blocks?

    So you have access to a CNC mill? Tooling will be your biggest expense if you don't have tools already available to cut the features you want (which may be the case, if you want micro-channels or something of the sort). As far as diagrams go, what kind of block are you wanting to make...

    Two Different Pumps, Same Loop

    It's been discussed before, try searching for parallel pumps or pump redundancy... Running them together inline is probably not a good idea. Replacing your 60gph pump with a larger one would be a better move. I can't suggest that you do so with the VA 1300 though, because I've gone through...

    What about using fuelfilters in a waterloop

    Fuel filters are also meant to be exposed to fuel, and not water. It's possible that there are metal parts in there that could rust or otherwise corrode, negating any benefit and probably worsening your problem.

    What about using fuelfilters in a waterloop

    You may want to reconsider the way you address peoples' ideas here. If you don't know why, refer to the rules.

    Overclocking Guide Intel and Asus?

    Then you missed this part? (9) No SHOUTING (Posting in all capital letters) It’s hard to read and just plain rude and annoying. Also, wait longer than 3 hours (like 24 hours) to bump your thread - this isn't live tech support. Thanks

    tline will rise the temp?

    No. A small res could possibly hurt performance by letting air mix in with the water. This won't happen with a t-line.

    Some pics of my rig for you to enjoy.

    I'm thinking in relative terms. At whatever flowrate you're thinking of, the blocks will always pose much more of a restriction.

    Custom Radiator Air Duct (watercooling)

    Ran it without a duct... but only with one fan and no shroud, so no valid comparison. Sheet metal, I think I cut it from pre-fab HVAC ducting.

    Some pics of my rig for you to enjoy.

    The tubing is undoubtedly a negligible restriction compared to the blocks. You need to consider & compare the flow resistance presented by each block before thinking about what difference 6" of large-bore tubing will make.

    Custom Radiator Air Duct (watercooling)

    That's similar to how mine's set up. A heatercore sits in my drive bays facing forward, wo 120mm fans sit on top of the case, and a duct connects them. Air goes in the front of the radiator and out the top of the case...

    Painting a heatsink

    Go ahead, just don't paint the part that contacts the CPU. In theory it'll lower your cooling performance slightly, but a thin layer can't be too bad in reality.

    Unique potential WC project - opinions please!

    Water being incompressible by external application of pressure is unrelated to density change by thermal expansion. Solids exhibit both of these characteristics as well; you can't very easily compress a block of 100% dense aluminum, however it will still change in dimensions, and hence volume &...

    Unique potential WC project - opinions please!

    Natural convection occurs by the same mechanism as ice floating in water - difference in densities of materials. It doesn't have to do with compressibility, and does affect fluids like water.

    what is "phase changing?"

    Your point, so eloquently stated I might add, has been taken. How about you relax, and either 1. don't post if you don't want to offer any further information, or 2. post your arguments in a civil manner. Thanks.

    calculating optimal mass flow rate?

    You're going to end up with such a rough approximation that I would venture to say it's not worth your effort to determine such selection criteria. The principle behind any decent block is some kind of extreme turbulence-inducing feature. I may be wrong, but I can't imagine that modeling this...

    calculating optimal mass flow rate?

    1- There is no vertical head if your loops is continuous, only frictional losses. 2- You're forgetting about the bulk of the restriction in the loop- the waterblock

    Radiator cleaning

    Actually, thewhiteguy did not ask a question, he stated his thoughts. Anyway, the answer to the question and the reasoning for the suggestion is because the acid in vinegar will dissolve copper oxide- that's why it's used for cleaning tarnished copper/brass items. How much good alone that...

    Radiator cleaning

    Vinegar is already extremely diluted, hence why you can safely ingest it. I'd actually be more inclined to find something stronger.

    My direct-die cooling system

    Unfortunately, those numbers on their own are meaningless in this discussion. Sure, water conducts heat better than air. But, you're comparing apples to oranges... As stated before, there are many other materials properties (density, heat capacity, viscosity...) as well as SYSTEM properties...

    My direct-die cooling system

    It's not obvious, because there are many factors that come into play in any heat transfer system. Think back, probably when most of you were playing with Legos (so was I, don't get offended). CPUs WERE cooled with no heatsink, sometimes without any kind of forced convection. Yes, there...

    Why not? I'm unfamiliar with the internals of typical evaporators for CPU cooling, do you have any pics of what you're referring to?

    Radiator cleaning

    There are many materials besides metals that are involved in metal manufacturing processes. Soldering/brazing flux and cutting oils are two examples which might apply here.
